Digital battlefield

72



The main direction of development of military equipment in the twenty-first century was the transition to the massive use of electronic devices and information technology. Such solutions are being introduced throughout the entire line of weapons and at all levels of the organization of the armed forces, from infantry infantry equipment to a global satellite constellation.

Digital battlefield


At the moment, the appearance of entire areas of military activity, which had been forming for centuries, is changing. For example, topographic orienteering and astronomical navigation have been replaced by the use of satellite systems GPS, GLONNAS or Galileo. These systems consist of a space and ground segment, connected by radio. The space segment is represented by several dozens of high-orbit satellites emitters, and the ground segment is represented by special receivers equipped with computing devices. The dimensions of modern receivers allow you to mount them in a computer case, a portable radio station, binoculars, or a laser pointer. The use of additional correction signals WAGE (Wide Area GPS Enhancement) allows up to several inches to improve the accuracy of object positioning. Interference immunity is ensured by the use of receiving antennas with a controlled CRPA radiation pattern.



The point-to-point radio communication invented at the beginning of the last century is increasingly being replaced by a zone subscriber-base station-subscriber radio, with the base stations located at the network nodes covering the space with cells in the form of reliable reception. This made it possible to switch to the use of a radio signal in the ultra-high frequency range, propagating within the line of sight, but at the same time allowing to transmit many times more information per unit of time than the radio signal in the UHF or HF range. A promising radio technology is CDMA - broadband transmission with coding of individual channels in the total bandwidth. It features a noise-like signal spectrum, support for hundreds of dedicated data / voice channels, or combining multiple channels for streaming video in the frequency range from 1 to 5 GHz (microwave).



For the reception and transmission of messages to zones under the control of the enemy, space communications are used, consisting of a group of low-orbit satellites and wearable radio stations. The low altitude of the orbits of satellites above the Earth’s surface contributes to the low signal power and the small size of radio stations, which practically coincide in size with commercial cellular phones. The passage of the orbits of satellites through the poles of the Earth makes it possible to achieve coverage with a confident connection of the entire earth surface. In addition to the omnidirectional whip antennas, the subscriber units also use remote, highly directional phased array antennas, which improve the conditions of the reception and transmission by an order of magnitude, reduce the radiation power and eliminate the danger of detecting a communication session with the help of radio intelligence.



Low signal power in one subscriber channel (CDMA2000 - 0,25 wadding) allows you to install base stations and repeaters on board unmanned aerial vehicles (UAVs), each of which occupies a position in one of the nodes of the radio network at an altitude of 6 km and provides reliable reception of a direct signal in zone diameter xnumx km. It becomes possible to maintain the redundancy of the number of node devices, thereby ensuring the stability of the radio network in the event of exposure to them by means of electronic warfare (EW), including missiles with homing on the radiation source. The same reservation method is used in satellite constellations of space navigation and communication systems.

Digital coding of a radio signal allows to combine voice, image and data in one channel, the latter being the most capacious source of information. The introduction of streaming encryption into subscriber devices devalued the possibility of decrypting information - using microwave communications, the amount of transmitted data becomes so great (including streaming video), and the encryption algorithms are so cryptographic that the data decryption speed will differ significantly from their speed encryption, thereby devaluing the information received.



Subscriber terminal devices have also changed significantly - their main difference was the presence of a video camera / thermal imager and a display. The size of the cameras has decreased to a few millimeters, in the short term it is expected to decrease to a few tenths of a millimeter. Cameras used in Vision Synthetic Aperture Systems switch to a multi-lens faceted design, such as the Swiss CurvACE, which provides all-round visibility and electronic image magnification without the use of optical-mechanical devices.



Displays of military-purpose subscriber devices are being developed in the direction of the shock-resistance of their panels, to the extent of giving them the flexibility of a wearable terminal of the automated command and control system FBCB2. Further miniaturization of displays and the approach of the screen directly to the pupils of the eyes with the separation of the picture into two components allows for the implementation of a three-dimensional image technology. Such devices in the form of augmented reality projection glasses with translucent lenses and built-in video camera, telephone headset and touch cursor are currently offered by many manufacturers, ranging from Microsoft to Vuzix.



At the same time, automated troop command and control systems (ACCS) develop in the direction of reducing the reaction time between detecting the enemy and exerting fire on him, as well as providing in real time the collection and dissemination of information about the tactical situation in all levels of command and control of troops and crews of combat vehicles. Progress in communications, navigation, on-board fire control systems (LMS) and wearable computers has allowed ACCS to be specialized in solving the tasks of the level of the headquarters of military units, units and formations. The stability of systems in combat is ensured by the network nature of information processing and storage, for example, the online tactical environment is automatically formed at three levels at once - in the wearable computers of the unit commander, his subordinates and the commander of the higher unit.



In addition to the onboard MSA, the capabilities of armament of military equipment are expanded by guided munitions. They contain head guidance systems (GOS) based on thermal or visible target signature, which have become an integral part of air-to-air and surface-to-air missiles, including ammunition for portable anti-aircraft missile systems (MANPADS). The use of the seeker for guiding missiles at air targets is facilitated by the good contrast of targets against the sky. The development of target identification algorithms against the background of the underlying surface also made it possible to switch to the use of the seeker in the design of missiles included in the set of anti-tank missile systems (ATGM), as well as in the design of guided artillery shells and aviation bombs.



However, GOS have a congenital deficiency - they are sensitive to the degree of transparency of the atmosphere in the visible and thermal ranges of the spectrum of optical radiation. With a large dustiness and / or smoke from the air over the battlefield, the target's range of capture by its visible / thermal signature drops sharply. The use of laser illumination of the target is fraught with the risk of the enemy using the means of optoelectronic and fire effects on radiation sources.



A more promising solution is the inertial guidance system (SRI), which is independent of the degree of transparency of the atmosphere and complete noise immunity. ISN is a set of three accelerometers located in three mutually perpendicular planes, and a processor-calculator. Each accelerometer consists of an annular fiber-optic resonator with mirrors, between which the oncoming laser beams propagate. Interacting with each other, the rays form an interference pattern, from which you can determine the magnitude of the acceleration. The processor-calculator determines the change in body position in space in accordance with the direction, magnitude and duration of the acceleration along each of the three spatial axes.



At the SPI, developed at Caltech, laser accelerometers and a processor-calculator are integrated in a single silicon microchip. Optical depressions are drawn on its surface — depressions with a length of twenty, a width of one and a depth of several tenths of a micron. Two rails pass along each depression, which form a light guide for a laser beam, ending with a radiation intensity sensor. On one of the rails installed measuring mass. When the mass under the action of acceleration deviates, then it bends the rail, thereby reducing the intensity of radiation. Analyzing this figure with the help of a processor, an accelerometer can register the mass transfer by several femtometers (proton diameter), which is a thousand times more accurate than the known laser accelerometers can do.



Inertial systems consisting of one microchip and therefore small in size, weight, and cost are intended for use in rocket-propelled grenades, developed by MBDA as an individual weapons infantrymen. Tiger grenades (weight 450 grams), Sniper (weight 1 kg) and Enforcer (weight 5 kg) with an accuracy of a few centimeters can hit targets with both direct fire (at a distance of several hundred meters) and hinged fire (at a distance of several kilometers) . The flight of grenades to the target is carried out along the most optimal ballistic trajectory using the terminal targeting algorithm.

The accumulated experience in the development of modern communication and navigation systems made it possible to begin the transition to an integrated technology of fire engagement of the armed forces. The US program PCAS (Persistent Close Air Support), implemented by Raytheon by order of the DARPA agency, is designed to make a breakthrough in the tactics of general arms combat. The program is scheduled for completion in 2014 year.



The new technology includes the following components:
- digital map in three-dimensional image;
- satellite positioning devices for equipping infantrymen and all types of military equipment;
- zone microwave communication with integrated data, voice and image transmission;
- guided munitions with ISN and GOS;
- projection glasses with built-in video cameras / thermal imagers, acoustic headsets in the form of ear vibrators (providing two-way sound transmission through the bone tissue, regardless of the level of external noise), touch cursors and inductive data transfer connectors in the IST of a wearable weapon;
- MSA wearable weapons;
- an automated troop control system in real time with functions of coordinating the actions of combatants, as well as collecting and transmitting information about the tactical situation by level of control.

All combatants are supplied with their own digital map copies recorded on solid-state media. Three-dimensional map image, incl. with data on the tactical situation, is projected on the translucent lenses of glasses with the combination of control points of the map and visible objects on real terrain. Manual target selection is accompanied by automatic determination of its coordinates, which makes it possible to produce an accurate direct fire shot or transfer the coordinates and type of the target to the OMS of the combat equipment providing fire support.



MSA wearable weapons made on the basis of a pocket computer with a ballistic computer. In one case with a computer, a microwave modem, a satellite positioning device, a solid-state storage medium and a port for connecting projection glasses are located.



Targeting wearable weapons in one of the following ways:
- small arms are induced by combining the line of sight of the target with a projection of a digital map, after which a ballistic calculation of the elevation angle of the trunk and the lead angle is made (in the case of a shot at a moving target), the calculation results are projected onto the lenses in the form of a refined line of sight;
- a rocket launcher is induced by the method of transferring an inductive connector from an infantry's MSA to an SPE, grenades arrow coordinates and targets (to ensure the grenade’s flight along a ballistic trajectory between these two points) with indication of elevation and lead angles;
- anti-tank / anti-aircraft missile is induced by transmitting an infantryman (located at the front position) to the rocket’s ISN (located at the closed position) coordinates of the launcher and target to ensure the rocket’s flight along the ballistic trajectory through the optical rocket’s ISN cable (using the fiber optic cable).

The implementation of the function of a ballistic calculator of all types of portable weapons in a single infantry OMS allows you to abandon the installation of electron-optical sights on each weapon, thereby significantly reducing the weight and cost of weapons.



First of all, the technology of the digital battlefield allows for a new way to organize the interaction of infantry units and army aviation in the form of UAV drums with guided bombs on the external load. The commanders of infantry units will be able to simultaneously perform the role of gunners and operators of weapons of UAVs, patrolling in the air at low speed outside the combat zone. The absence of a pilot cockpit, armor protection and gun armament, as well as the use of bombs instead of missiles on board a UAV, allows you to multiply the payload. After the transfer of the coordinates and type of targets from the SLA of the infantryman to the SLA of the UAV, the aircraft automatically switches to a set of speed and altitude, and then drops bombs from the tailing without entering the enemy’s air defense zone. Bombs fly in a ballistic trajectory under the control of the SPV. If it is necessary to hit mobile targets, bombs with an additionally installed homing unit are used.



In the final version, the technology of the digital battlefield completely names the nature of the operations of the ground forces in the tactical unit-brigade link, leaving behind the infantry only the functions of reconnaissance and guidance of artillery and aircraft strikes, which serve as platforms carrying high-precision weapons. When carrying out combat operations in an urban environment, guided rocket-propelled grenades will be used as the main infantry strike means. As a result tank the troops will get rid of the tasks of assault guns and will be able to concentrate on maneuvering operations in the depths of the enemy’s defense. The main factor in achieving victory will be the fire, rather than a quantitative advantage in manpower and equipment.

    Well, promising areas, how to deal with all this?

    Perhaps there is an effective method using new physical principles in weapons.
    For example, to block any radio communication creating a strong ionization of air in the atmosphere in the required location of the EARTH.

      Powerful generators of electromagnetic pulses were created by our designers. This makes it possible to display the electronics, computers, communications and control equipment of the adversary on the TVD. The electromagnetic pulse of the generator is comparable to electronic. magnetic impulse when using nuclear weapons!

      Yes, everything is simpler ... To land all the satellites, or to make them a sieve, to burn the exact electronics with equipment and planes with electromagnetic bombs, and then you can roll them out onto the T-62, BTR-70 mig-17 and melee laughing somewhere like that ... Total business then. wassat

    That is why the role of electronic warfare systems is growing in the modern theater of military operations. The electronic warfare service has long been in need of modernization. What is now in service is no longer included in any framework.

    All these digital technologies look beautiful if on the battlefield, on the one hand, an army such as the US Army is fighting, and on the other, Afghan partisans are Taliban with grandfather's wines.
    As soon as it comes to the confrontation of armies close in strength, then all these technologies will "fall" in a matter of minutes and the aforementioned grandfather's vintar, a well-sharpened Finnish and a Molotov cocktail will be among the most reliable and popular means of armed struggle on the battlefield.
    I affirm this as a person who devoted about forty years of his life to these very digital technologies.
    And you will not need any super-wise electronic warfare means for this to happen. It will be enough to detonate a couple of three electromagnetic bombs for the EMPs they generate to disable all "kibenimatics" and not only it.
    Then. I hear, see, manage ... with the help of flags, bonfires and the great Russian mat

      So far, not a single case has been recorded of the use of ammunition in combat that creates an electromagnetic pulse of high power, despite the fact that the line of their existing models begins with a hand grenade with an ordinary explosive and ends with a special high-explosive nuclear warhead.

      This is due to the fact that protection against EMP is very simple - shielding electronic equipment with a thin layer of metal, for example, foil, not to mention the armor of military vehicles. A fuse is built in between the equipment and the antenna, which in the case of an electromagnetic pulse is destroyed and breaks the galvanic connection between the antenna and the equipment.

      After replacing or automatically switching to a new fuse, the antenna-hardware complex will continue its work.

      Electronic equipment that does not have an antenna output, for example, inertial guidance systems for shells / missiles / bombs, will not even notice the use of EMR weapons.

        There are no child prodigies. Tales of EMP are just fairy tales. Do not forget that all the radio parts, fenced in by the warriors, are delivered in ceramic or metal-ceramic cases, then it is shielded by a cover plate, and then it is shielded by a case. I think, in the vicinity of the epicenter, still part of the radio can be substantially damaged. The satellite constellation will definitely cease to live, but not from the EMP, but everything else is unlikely.

          In addition, how will we deliver? We’ll deliver a rocket and blow up a bomb in the atmosphere? This is a nuclear war, gentlemen’s war, no EMP is especially interesting to anyone ...

            Wunderwaffles, as you definitely said, do not exist, but no one says that EMI shells are such, besides you need to know how to use them too (I launched one HE and all the electronics within a radius of 10 km died, let's be realistic - this is not at all a fact).
            But isolation from EMR is completely nifig (I’m sorry) in reality it’s not so simple, there will be at least a small gap in the protection, a small gap or heterogeneity - and write everything has disappeared, this topic is relevant for all devices now (this is known to everyone who soldered the amp itself) For example, one of the bottlenecks is the connector sockets, if one module can be perfectly insulated, the wires all the more, then the connection of the modules is still a lot of fun.
            And with the antennas it’s not so simple, the fuse needs to be changed very quickly on the one hand (efficiency, restoration of command, etc.), on the other hand, those who hit the EMP with projectiles can wait, make a second volley in a minute, for example, and what is behind the fuse again to climb? (let’s leave out the details of what might happen to the shooters after the first salvo). And technically, protection against EMR of the receiving part (where the antenna ended and the receiver with the processing unit started) is not the easiest thing and the fuse is not so simple there and it only gives a chance that the most expensive part of the equipment will not burn, but how quickly it will have to be changed and how often with more or less regular shelling?
            In general, there are still too many questions, one can say there is no panacea, you will put on a bunch of convenient electronics and it doesn’t matter how it fails - this is a pancake war and what will the soldier who relied on it in everything, with the other without modern means of data transfer and their processing, the conduct of hostilities in the current conditions is simply stupid, too much military advantages

              Now the problem of concentration of all electronic components of infantryman’s equipment in one communicator is the size of a smartphone, protected by a metal case and equipped with only one galvanic output - an antenna.

              The antenna output is equipped with an automatic fuse against power overload. After the decay of EMI radiation, the fuse will restore the communicator to the antenna.

              The information output of the communicator can be made in the form of a fiber optic device and projection glasses.

                Hmm .... Very logical, there are a few more questions that have emerged from your explanations of the technical details:
                1. Communication with an individual soldier is carried out due to a narrowly directed microwave beam propagating - in a straight line and for the implementation of such a scheme, UAVs are necessary respectively, there is a question of overcoming physical obstacles by this beam, for example, when acting in mountains or urban conditions, respectively, indoors, caves, equipment and etc.
                2. To implement the all-round operation of this antenna device, the soldier is "equipped" with a remote antenna device at the level of his head (well, I thought about it myself), what are its approximate dimensions and weight (of course, when using modern PAR elements, it should not be large and heavy ) and if it has a different method and place of attachment, unsubscribe
                3. There is still a question regarding the duration of non-recharging operation of the whole device. Though presumably. Not all military operations take 2-3 days.
                4. Are there any assumptions on the implementation of the system and the controls for these devices (this question naturally follows from the 2-3rd)
                Thank you very much in advance for your reply.

                  1. Quite right, when using a gigahertz radio signal according to the "top-down" scheme, there may be dead zones at the foot of a mountain / hill with a steep slope of more than 45 degrees and a repeater UAV on the other side of the mountain / hill. The solution is to move the repeater UAV to one side of the mountain / hill with the infantry.

                  It is also possible the occurrence of dead zones in rooms with ceilings. The solution is the location of a temporary ground-based mini-repeater at the entrance to the room.

                  Generally speaking, artillery / air support is not required when storming enclosed spaces (grenades, rocket-propelled grenades and small arms are used), so the lack of online communication with support forces is not critical.

                  Online communication with support forces is used on an open battlefield to draw close to an enemy entrenched in defensive structures, up to a throw distance of a hand grenade (30-40 meters). Such a peculiar method of comparing the chances of attackers and defenders.

                  2. Absolutely, the infantryman’s radio transmitter headlamp should be located at the level of his head - in the form of a lattice located on the surface of a helmet made of high molecular weight polyethylene. The grill can be made in the form of a printed circuit board.

                  3. The operating time of the microwave transmitter in reception mode can be increased to 7-10 days in the case of using a fuel cell with ethanol. On the other hand, the capacity of lithium-ion batteries is also constantly growing.

                  We must take into account the fact that the rank and file of the infantry squad in an attack will mainly be used to provoke the enemy to open his firing points. Their radio transmitters will work mainly to receive the tactical situation and the commands of the squad leader. The latter (by virtue of his qualifications) will be the gunner of the support forces to destroy the identified targets, using his radio transmitter to transmit commands (voice) and coordinates (in the form of data). Therefore, it has spare power supplies by reducing personal ammunition.

                  4. The infantryman’s communicator control can be implemented by connecting the communicator and projection glasses with a complex cable containing:
                  - a pair of optical fibers for transmitting a computer image and infrared radiation (to illuminate the pupils of the eyes) to the prism projectors of glasses;
                  - an optical fiber for transmitting reflected infrared radiation to the communicator to determine the position of the gaze, i.e. the cursor in the field of view of the glasses;
                  - an optical fiber with a micromirror at the end that responds to a finger pressing the bow of glasses in order of subject selection of a target or an on-screen menu item after moving the cursor;
                  - a pair of optical fibers that transmit thermal images of the area from micro-lenses located on both sides of the eyepiece of the glasses to the communicator.

                      In fact, the American DARPA has already outstripped the solution described above and made projection contact lenses instead of glasses. How information is brought to them is not disclosed.

                      So we, if you want, if you don’t want, will have to catch up. Russian firms have already bought plants for the production of 65 nm processors abroad. You see, in a couple of years, 22 nm processors will be sold to us. This will be enough to develop a compact infantry communicator and projection glasses.

                      The main thing is that the software is domestic, without bookmarks. Our programmers are qualified, it is up to the will of the state.

                        Do you think that a Russian conscript infantryman with a "DOOM" education will be able to apply this?

                        It is such a recruit who has shot in Word of Tank and will be able to apply the technology he is familiar with, which consists in pointing the cursor at the target and pressing the "confirm" button.

                        By the way, I have a suspicion that the US Army contract soldiers are not far from our conscripts, since DARPA is so invested in digital battlefield technology.

                      The lenses seem to me unreliable, the service life is calculated for months, they tend to cause irritation and require special storage, they are easily lost, there is also a nuance that I did not really like the control is carried out using a high-frequency transmitter, according to the principle it resembles as if you put small steel shavings on the table, and then move a magnet from the back of the table, maybe in those 5 years since this technology first appeared, they were able to establish feedback, but the very method of "application" seems to me somewhat problematic for the military

                  Thank you very much for your response. A few more clarifications:
                  1. I am afraid that when storming the premises or being in them, it is nevertheless necessary to keep in touch with the headquarters, in case of a change in the situation, the subunit may remain in the dark if the connection is interrupted, in addition, if it is necessary to return target designation due to some kind of "closed" points, problems can arise, and the placement of repeaters or additional UAVs can unmask the detachment. An interesting option would be for such cases to give the commander a more "standard" radio in an emergency (with certain modifications, of course)
                  3. If the operation lasts several months in isolation from the main forces, then you will have to pervert with the power supply system, I saw options with flexible solar panels of increased survivability (efficiency does not drop so much with bullet breakdowns and other damage) and the question is interesting about fuel cells but how much they will weigh. Another interesting topic is that power is mounted in the main processing unit for the sake of increasing reliability, how long one infantryman will need to carry them and how to replace them (so that they do not cover them yet)
                  4. Controls require quite a lot of complex small-sized elements and good optical fiber as far as the voiced systems are really implemented, taking into account that there are no adjustment and control systems in glasses (except for electronic circuits, which may not burn out if something happens) and how much this system in principle will be reliable (it only depends on the sophistication of the system) and tenacious

                    1. You are right - in enclosed spaces, communication devices such as VHF and HF are not excluded. The transmitters of these ranges themselves (provided that a microwave / VHF or microwave / HF adapter is installed on an additional antenna input) can become repeaters between infantry communicators and a higher command communication center.

                    It all depends on the radio permeability of the walls and ceilings of enclosed spaces - if there are no walls or are light partitions, then a ground-based microwave repeater installed outside the premises during the assault can also provide communication.

                    When storming factory floors and workshops, it makes sense to storm their roof before the storm to organize direct radio visibility from the UAV.

                    During sabotage and reconnaissance operations behind enemy lines, a wearable satellite communications terminal can be used to communicate with the command, which simultaneously (using a microwave adapter) acts as a trunk base station for communicators of special squad fighters.

                    Naturally, the simplest option is also possible — a non-relay mode of communication (intercom or two-way) between infantry communicators of the same unit within line of sight.

                    3. The technology of the digital battlefield is primarily oriented to the use in linear infantry units, which have the ability to take a break of at least a few hours between operations. At this time, it is possible to recharge the batteries of the communicators from the BTR / BMP generator.

                    The size and weight of fuel cells for alcohol coincides with similar characteristics of lithium-ion batteries an order of magnitude smaller capacity.

                    It is advisable to place the built-in lithium-ion battery in the infantryman’s communicator’s case for 48 hours in reception mode, as well as include a portable fuel cell (also shielded) in the infantry’s equipment, from which it will be possible to recharge the internal battery from time to time using the appropriate connector.

                    Solar panels are welcome for reconnaissance and sabotage groups.

                    4. According to common sense, information communication between a communicator and projection glasses is possible using a single fiber, the bandwidth of which is divided into optical ranges:
                    - visible for projection of a computer image on the lenses of glasses;
                    - infrared to illuminate the pupils of the eyes / transmit reflected light to the communicator (in pulsed mode);
                    - thermal for transferring terrain images from micro lenses to the communicator.

                    The communicator can be controlled by voice or hand gestures taken by the thermal imager.

                    With this approach, a set of LEDs that modulate radiation in the corresponding spectral ranges and an array with detecting sensors will be required. LEDs and sensors are located in the communicator case, prism projectors and micro lenses are in the case of glasses.

                    Fiber optics must be protected against mechanical stress with a power braid. Glasses should be made only of high-strength composites and polymers, allowing them to fall on concrete from a height of human growth. The metal case of the communicator (the most expensive element of ammunition) must withstand even greater loads.

                    The external HEADLIGHT of the communicator can be located on the surface of the infantryman's helmet on the model of the domed HEADLIGHT of the radio locator developed within the framework of the ROC "Morpheus" (see my comment from 11:48). The antenna is connected to the communicator with a shielded cable. The antenna input of the communicator is protected from EMP by means of an avalanche-flyby diode.

                    Everything seems to be reliable and compact.

              Another question about the EMR protection system in the form of an automatic fuse between the antenna part and the receiver, it’s curious how it is implemented, it’s just interesting, if possible without too in-depth description, antenna receiving and transmitting devices, the theory of circuits and signals, as well as electrical equipment and the work on these topics is not connected with me, so my knowledge can only be attributed to fairly general on this topic.

                  Faced with such. Look at the reaction time in your link, it's a few microseconds. Usually this is not enough, even with a power of several GW. And when an electromagnetic bomb is detonated, the power of the pickups is ten times stronger than when lightning strikes. I am sure that any standard protection device is just carbonized. In general, of course, you need to test and watch, much depends on the front of the impulse, too.
                  In Belarus a few years ago, it was possible to see the effect of EMR in the first experiments with vircator and its effect on the computer. The radius then was small, several tens of meters. Comp beautifully exploded and smoked. In Russia, these works seemed to be carried out in the Tomsk Energy and the results were good. What condition is difficult to say now, especially after Serdyukov.

                    The key parameter of an EMI weapon is its range of action.

                    If the desired power level of the electromagnetic pulse is stored only at a distance of several tens of meters, then it is more efficient to use a warhead with a directed flow of ready-to-use striking elements, since it always gives a 100% result in hitting a target, unlike an EMP, where everything depends on the degree of screening of the target’s electronics.

                    And with an increase in the distance, the pulse power decreases quadratically and the performance of simple fuses is sufficient.

                    It is possible that there are more advanced solutions to breaking the galvanic connection between the antenna and the receiver, but unfortunately they are not known to me.

                      Well, how can I say, the pulse energy, the radiation time, the penetrating depth for, for example, reinforced concrete, granite, soil, etc., also I think are of no small importance, in the end this weapon is one of many types used and its essence is to limit or deprive the enemy of information and technical advantage in conditions including when direct destruction of the target is complicated or impossible.
                      So that while communications are being created and developed, weapons are being created and developed against them, and different things.

    Sergey, the fact of the matter is that between the main rivals i.e. Russia with its allies on the one hand, and the United States with its allies on the other, no other war is expected except nuclear,
    And even if some kind of war begins between them as limited i.e. without the use of nuclear weapons, then very soon it will turn into unlimited using everything that can be used, including nuclear weapons.
    And in the conditions of nuclear weapons, the main striking factor for any control systems, including ASUV of the battlefield, will be not only and not so much the shock wave, radiation and infection, as well as the thermal effect, but the electromagnetic radiation generated by the use of nuclear weapons and special ammunition, in which the bulk of the explosion energy is converted into electromagnetic radiation energy.
    There are already a number of other means that create powerful EMR without explosion. Who are interested, google in the sections concerning Directed Energy Weapon.
    As for all the above gimmicks and tricks like protective circuits at the input of electronic equipment, these little tricks were known back in the 70s and 80s, when the first domestic ACCS of the "Maneuver" type were created, modifications of the elements of which are now known as fundamentally new ACCS elements " Constellation". (No wonder they say that new is well forgotten old)
    So, back in those years, and with that almost unlimited funding for the development of such ACCS, their developers came to the conclusion that ACCS data are unlikely to work stably under the conditions of massive use of electronic warfare means, and especially in the case of creating EMP. After all, the exchange of data in ACCS is carried out mainly via radio communication channels, and to suppress them, no special efforts are required. And then what's the point of all these protective chains and "footers"? By the way, the ACCS data have never worked steadily even without the influence of electronic warfare equipment, even in peacetime. The reasons for such instability and insufficient training of "exploiters" and the low level of reliability of domestic special computers, and rather frail element base (microcircuits, transistors, etc.) and much more
    The fact that EMP has not yet been used in local wars is also understandable, because it's a double edged sword. One hits the opponent with the other on his own. But I don’t really want to, because it can be more. Now, when survival in a big war is at stake, then everything will go into play.

      Subscriber radio transmitters protect against the effects of electronic warfare by using phased array antennas with a controlled radiation pattern - only to the base station. In other directions, including to sources of interference, a zero sensitivity of the antenna is formed.

      This is achieved by combining a radio transmitter (modem) with a computer (processor) and a navigator (inertial system), the joint work of which supports the orientation of the radiation pattern to a given point in space, regardless of the position of the radio transmitter.

        the meaning of the interference is in a more powerful signal at the frequency of the enemy transmitter in the area where the enemy is supposed to be located. No antennas will help here. If the communication frequencies "go over" then you can jam the entire range. In any case, it is easier to make a jammer more powerful than individual communication means.

          Interference plays a role if the base station is equipped with an omnidirectional antenna.

          If a controlled phase array is used as an antenna, then a zero sensitivity ("eyesore") in the direction of the space segment where the source of interference is located is formed in its radiation pattern by software.

          A radio signal in the gigahertz frequency range propagates exclusively in a straight line, similar to light, therefore software shielding of a powerful radio signal source (interference) helps to "see" weaker radio signal sources (subscriber radio stations) in space.

          The problem can arise only in one case - when the source of interference, the subscriber station and the base station are on a straight line. In the case of airborne deployment of a base station (on board an UAV) and ground-based deployment of subscriber stations and an interference source, this is physically unattainable.

            Damn, the Internet is shutting down ... If I understand correctly, the source of interference cannot clog the base transmitter with a phased array? - so it is not necessary - to send the interference to the base station, it is enough to clog the area where the subscriber stations are located. So what if the base station "squinted" towards the source of interference, if the level of the interference signal in the area of ​​subscriber stations, at the frequency of the subscriber stations' emission, exceeds the power of subscriber stations. Perhaps they will be able to work for reception, but not for transmission.

            Well, let's say they "pull" individual subscriber antennas with a phased array and access through the side lobes will become impossible, but along with the idea of ​​placing many emitters next to such a transmitter, the idea remains - to hang several "chandeliers" above it so that they "mirror" the radiation of the base station to it ... That is, the same electronic warfare UAVs over the place of the alleged location of the enemy

              The base station on board the UAV is in the air at an altitude of 6 km in the depths of its territory (from 1 to 6 km), is protected by an air defense / missile defense system and fighter cover.

              The enemy's attempt to hang in the air at the same point (above / below / next to the base station) their "electronic warfare chandeliers" will end in their destruction online.

                I understand that the described scenario is similar to the actions of a reconnaissance group or spotters on our territory. In this case, the chandeliers are hung in the alignment of the radio channel diagonally above our territory. But tell me, another idea is that what if you use the microwave oven not to burn their equipment, but to ionize the atmosphere in the cone of the radio channel?

                  The scenario is described as typical for providing communications for its units that do not cross the front line:
                  - air suspension of the base station on board the UAV over its territory at an altitude of 6 km;
                  - in the case of defense, the suspension point is 6 km from the front line deep into its rear;
                  - in the event of an offensive, the suspension point is close to the front line up to 1 km deep into its rear.

                  The reason for the airborne location of the base station is simple - the GHz radio frequency signal propagates in a straight line and is strongly shielded by any vertical obstacles, including the walls of buildings and tree trunks. Therefore, to ensure guaranteed communication, the radiation of the base station should be directed from top to bottom at an angle of at least 45 degrees.

                  At the same time, a number of other problems of any radio communication are solved:
                  - protection from sources of interference (when using the PAR);
                  - providing radio communications regardless of the terrain (up to a height of mountains of 6 km);
                  - a large area of ​​radio coverage using one base station (circle with a diameter of 12 km).

                  To ionize the air in the cone of a radio channel at a distance of 6 km or more, a transmitter-ionizer with a power of three or more orders of magnitude higher than an interference transmitter will be required. Even if it can be technically released, the ionized region in the airspace will be very sensitive to wind drift and / or to the horizontal movement of the UAV with the base station on board.

                    it is clear that the chandeliers are still real, and the wind drift of the atmosphere is not critical (just in case, I will note that there is a narrower part in the cone, and it is not at all necessary to "boil" excess air masses), although, in general, I agree - the idea damp

      No way, therefore, the control system of promising ATGMs consists of two guidance systems - inertial and thermal imaging.

      The inertial system ensures that the missile flies from the starting point (from a closed position) to the target area (the coordinates of which were transmitted by the advanced gunner), the thermal imaging system allows the missile to self-aim at the target at the end of the flight.

    Already, the war is becoming very expensive, even for the United States. Therefore, there is no need to talk about the mass distribution of such technologies. Moreover, a really simple electromagnetic bomb can remove all this expensive electronics within a radius of 20 km. By the way, even the ignition coils on the machines fail, the batteries and the power cable are torn to pieces.

      Electronic components (inertial system, radio modem, projection system), in connection with their miniaturization to the size of the processor chip, are reduced by one or two orders of magnitude.

      For example, the computing power and memory capacity of a handheld computer with a built-in modem and touch screen (i.e. smartphone) exceeded the performance of a desktop computer 5 years ago, and the price decreased tenfold.

          They screen electronics and electrics (the latter should not have galvanic connections with external devices at all). Antennas are connected to the electronics through fuses operating on the power of electromagnetic radiation. After their automatic operation, communication is restored within a few seconds.

          If you use domestic electronics and software, then complete verification of products / programs will not be required (only selective by military acceptance), and certification will be carried out only by the whole production (at start-up) and specialists (when hiring).

Some of which have already been commissioned, but even the richest army in the world is still leading the process of systematizing them and introducing these systems into a single complex (I mean they’ve worked out, there are already existing ones, but it seems to me that they are still in field trials).

          A relay UAV barracks in the air strictly above its territory and is covered by an air defense / missile defense system *. Therefore, any enemy projectile / missile will be intercepted on approach to the UAV.

          It should be noted that this is still a fantasy, because when all this normally works then specific means of counteraction will appear.
          And so - the directed shrapnel until the moment of the projectile defeat is quite, and there is no noticeable success among the bourgeois in interceptors.
          Here about the wunderwafl put to the Syrian rival, which could not knock out the BMP here I read, but about the super interceptors - I'm sorry, the anti-plumbing dome does not count.

      The communication channel is a radio beam, directed strictly from the infantryman to its relay UAV, and from there to the shock UAV in its rear.
      The question is how do fools know the coordinates of an infantryman and an UAV? bully

        In fact, quite simple. Any directional antenna has side lobes, i.e. radiates to the side. They are of course less than the main beam in power by 10-15 dB, but this is usually enough to detect this, unless of course a special encoding such as WCDMA is used.

          The radiation power of an omnidirectional antenna of a CDMA radio transmitter is 0,25 watts. The radiation power of the main beam pattern of the PAR (with a beam angle of several degrees) is less by one or two orders of magnitude.

          What will be the radiation power of the side lobes of the PAR, including when effectively suppressed?

            To provide several degrees in the highest frequency range of CDMA 2100 MHz, and this wavelength is approximately 15 cm, it is necessary to have an effective antenna area of ​​several meters (about ten). Count for interest. And the PHAR is not a panacea, the physics for it is almost the same as for the mirror. In addition, the cost of the most primitive PAR is much more expensive than a UAV. For example, in the S-300 air defense system, the cost of the phased array is approximately 50% of the SNR. So there, the beam width is exactly 1 degree in power loss of 0,5, in the range of 3cm. Estimate the size!

                Read carefully. This is a technical solution for a communications satellite. AFAR Ka-band (30 GHz 15 times higher than CDMA frequency) based on multilayer printing technology. Transverse antenna sizes of 50x50 emitters are 25x25 cm2. The PAR gain was 32,7 dB, the maximum forside radiation level - minus 13 dB(I talked about this above), the width of the main lobe at the level of minus 3 dB - 4,3x3,6 deg (much more)

                  I agree, you understand this better. I could not find on the Internet an example of a compact headlamp specifically for radio communications in the gigahertz range.

                  However, it is clear that such antennas are or can be created on the existing element base, since the requirements for the formation of a radio beam are much lower than that of radar antennas.

                  In the case of the temporary absence of such antennas in the arsenal of infantrymen on the battlefield, elementary traps for EW shells / missiles can be used - the simplest emitters with an increased power level compared to the signal strength of subscriber radio stations.

                  Therefore, an attempt to shell individual infantrymen with EW shells / missiles will end only with the overexpenditure of these expensive ammunition, which self-aim in traps - emitters.

                  The headlamp located on the left of the photo is designed to operate in the X-band of a radio communication with a frequency of 7 to 10,7 GHz, i.e. belonging to the same centimeter range of radio waves as the upper limit of the proposed microwave communication.

                  The diameter of the PAA PCB is 8 inches or 203 mm. If the antenna is made in the form of a hemisphere, it can be entirely placed on the surface of the infantryman's helmet, following the example of the domed HEADLIGHT of the 29YA6 radar, developed within the framework of the Morpheus ROC

                    Cool. We had one such warrant officer, the doctors prescribed UHF to him, and he decided to warm himself up near the included radio altimeter. A month later, an autopsy showed that death came from the fact that the liver was cooked.
                    But seriously, really spherical headlights can significantly reduce the dimensions of the antennas. But while they are too expensive, their area of ​​application is satellites and aviation.

                      The radiation power of the antenna of the subscriber radio transmitter of the CDMA standard in the gigahertz range, as it was said, will be less than 0,25 watts. With the same success it is possible to "weld" the brain by radiation of a 1 watt GSM cell phone antenna.

                      In addition, the inner surface of the dome antenna is covered with a metal screen, so the radiation will under any circumstances be directed away from the infantryman, in contrast to the known antenna designs of wearable radio transmitters and cell phones.

                      To reduce the cost of the dome antenna for its manufacture, you can use flexible printed circuit boards based on polyimide metallized from the inside. The board is embedded in a Kevlar helmet and connected to it with polymer glue. Then, a shock-absorbing structure with fastening straps for the infantryman’s head is glued inside the helmet.

                        The UAV repeater is suspended in the air at an altitude of 6 km, the distance from the front line is from 1 to 6 km, the distance of the position of the enemy anti-aircraft guns from the front line is about 10 km. Those. an ordinary anti-aircraft projectile must fly a distance of about 15-20 km to get to the calculated point of meeting with the UAV.

                        Such a distance in the forces to overcome only 152/155-mm projectile in a period of not less than 30 seconds. The projectile flight path is easily calculated in fractions of a second according to the data of the artillery shells and mines radar. UAV barrage speed is about 30 m / s, i.e. during the flight of the projectile, he will leave the calculated meeting point at a distance of at least 900 meters.

                        In addition, the same radar will allow you to calculate the location of the anti-aircraft gun, which will be hit back during the flight of the anti-aircraft projectile. In the best case, the enemy will exchange one UAV for one anti-aircraft gun (most likely, a self-propelled gun).

                        Instead of a failed UAV, the communication in its coverage area will immediately be taken by neighboring UAVs located at the vertices of the same radio network cell (with mutual overlapping of the zones). After some time, the place of the outgoing UAV will be taken by another device, which has risen into the air from a ground reserve.

    The modern digital battlefield is almost 100 percent under the control of the element base developer, that is, the US government. At the same time, the work of "Voevoda" in astronavigation provides an accuracy of 300-500 meters (for a nuclear warhead). Is it bad?

    Understand that a reliable intelligence and command system has always been the most important in any war, and in modern warfare, without automated digital information processing on the battlefield, you can only die heroically. However, now there are a lot of deliters and comers in power who are trying to warm their hands. The thing is that big money is allocated for R&D and it is spent almost without control. Moreover, like any scientific work, OCD can have a negative result. So there is an incomprehensible advertisement, fantastic projects that are not grounded in anything. The main thing is to throw more dust in your eyes and get the appropriate funding. At the same time, real highly effective technical solutions are simply wrapped up, they are not profitable for officials, since they do not allow them to siphon money from the budget, which through various structures and contractors ends up in the pockets of the "necessary" people.
