The specialists of "Radar MMS" know how to put intelligence into a rocket, a bridge support and much more.

The exhibition exposition of the unique Russian enterprise “Radar Mms” at the military-technical forum “Army-2015” and the International Naval Salon-2015 aroused a wide interest of specialists and ordinary visitors. Anyone could see not only unmanned aerial vehicles, precision guidance systems weapons etc., but also IL-114 flights with the Kasatka search and sighting system installed on board. The Executive Director of NPP Radar MMS, Candidate of Technical Sciences Ivan Antsev told the Military-Industrial Courier about what surfactant technology is and how UAVs are used in Russia.

- Ivan Georgievich, familiarize our readers with the products that were presented at the last military exhibitions?

- First, our company has introduced a homing system for various types of precision weapons. I want to note that GOS is the calling card of our company, serial production, which we are constantly improving.

In addition to the homing heads, Radar Mms leads several more directions. In particular, unmanned aerial vehicles were presented at the exhibition. We also demonstrated magnetometric systems, the Kassatka search and sighting system and its elements, and various radar devices, including the millimeter range. Specialists could familiarize themselves with the helicopter landing support systems, which are being created on the basis of the millimeter-range radar stations Visibility-2000 and Mini-Radar.

We showed our sensors, including precision, temperature, humidity, pressure. Meteorological complexes based on these products were presented. And I want to emphasize, this is serial production.

In my opinion, the most important part of the “Radar MMS” exposition was products using the effect of surface acoustic waves. For example - the identification sensor. The main difference between these SAW sensors from conventional semiconductor - range. Our products can passively receive information at a distance of up to 50 meters, which does not allow for the implementation of samples that use semiconductor solutions.

In addition to identification, we showed surfactant sensors of physical parameters: temperature, humidity, pressure, etc., as well as a device capable of capturing microdisplacements. Such a sensor capable of signaling the state of the construction of various structures is undoubtedly necessary in construction, including on special objects.

Finally, “Radar MMS” presented such a promising project as a medical invasive sensor that is implanted in a human body, for example, on a prosthesis, and provides control of its engraftment. Currently this is a big problem in surgery. After all, when a prosthesis is already inserted, it is impossible, guided only by the study of external factors, to understand whether there is an inflammatory process or not. With the help of our sensor, such control has become a reality.

- The “flying laboratory” of the Il-114 with the Kasatka search and sighting system on board caused great interest not only among specialists, but also among ordinary visitors. Tell us about this product.

- Indeed, at the exhibition our company presented the “flying laboratory” of the Il-114 with elements of the Kasatka search and sighting system. By the way, this aircraft is an active participant in the flight programs of major international forums. “Killer Whale” is an air-based complex. It consists of radar equipment, optoelectronic devices, the work of which is united by an information management system that performs integration, processing and geo-referencing of information.

- The creation and use of unmanned aerial vehicles has become one of the priority areas not only in Russia, but also in the world. So, of course, I would like to know that “Radar-MMS” has already been done in this direction?

- We believe that there is a future for unmanned aerial vehicles. And no matter what kind of UAV it is: a multicopter, an airplane, a helicopter ... “Radar mms” headed for the development of a UAV for a long time - back in the 2003 year. And I want to emphasize that we have achieved some success in this direction.

At present, the parametric range of our UAVs is very wide. These are machines with take-off weight from 8 to 500 kilograms. This summer at exhibitions we present two devices. One is 37 and the second is 500 kilograms.

The scope of our UAVs is quite diverse - civilian work, rescue operations, assistance to law enforcement agencies in their activities, etc. And of course - the military sphere.

Our products have already attracted the attention of such departments as the Ministry of Internal Affairs, the Ministry of Emergency Situations, the Ministry of Transport and the Federal Road Agency. Radar MMS has samples that are interesting for oil and gas enterprises.

It is noteworthy that in this way, the modified BPW-37 flew near St. Petersburg in the area of ​​garbage dumps, where they measured the level of CO2, the emission rates of harmful substances. According to the results of the work and the data obtained by the experts, a report was drawn up and conclusions were prepared.

We supplied AVIS unmanned aircraft to the police. They are used to monitor the traffic situation.

And we use BPV-37 for several years in a row to provide rescue in case of need. This is especially true in spring and autumn, when the ice is thin enough. We find a flock of people on the ice and transfer their coordinates to the Ministry of Emergency Situations.

I want to note that the BPV-37 is the most popular drone helicopter at the moment. Airplanes are of less interest to our customers. They have a number of advantages, but on the other hand, such UAVs have a serious drawback - the requirements for sites for takeoff and landing. In any case, we need some kind of no, but the glide path, we must take care not to interfere with the forest. The helicopter has no such restrictions.

By the way, the preparation of the operator on the BPV-37 takes only one to two weeks. It is desirable that the student had a technical education. But we can prepare people without it - it just takes a little more time.

- Head units with guidance systems for precision weapons are, as you said, the hallmark of the enterprise.

- The main products of Radar MMS are intelligent radio-electronic and combined control and guidance systems for high-precision weapons. Our company develops and serially produces guidance systems for universal, all-weather and cruise missiles of land, sea and air-based, functioning at any time of the day.

The highly intelligent homing systems, developed by JSC "NPP Radar MMS", were the first in the world to use the aperture synthesizing mode, which is effective when working on ground targets.

The developed radar homing systems ARGS-54E, ARGS-35E, ARGS-59E, ARGS-14E for 3М-54E, 3М-54Е1, X-35E cruise missiles, NNXX-35E, X-59E, XNUMX-XNUMXE, XNUMX-XNUMXE, X-XNUMXE radar systems Club-N, Club-S, Club-M, Uran-E and Bal-E missile complexes.

I want to note that our products are in demand among foreign customers not only as part of ready-made products. Currently, a number of countries have signed contracts for equipping the enterprise with advanced systems and modernizing the existing ships of their naval forces.

- You mentioned the so-called surfactant technology. Let's explain to readers what it is?

- Surfactant - surface acoustic wave that propagates through the sound duct. As a rule, the piezoelectric effect is used to excite the surfactant. The most widespread are quartz, lithium niobate, langasite. For products using surfactant technology, one can obtain a reflection of this wave from certain nanostructures formed on the duct, and accordingly - information about the physical quantity.

The know-how of our company is the creation of these very nanostructures on the sound ducts. Moreover, the structure must be of a certain form, that is, we create the topology of the device.

Such materials with already applied "drawings" are used primarily to create passive wireless sensors. An electromagnetic wave that arrives at the antenna is already converted into an acoustic, essentially mechanical wave, which propagates along the surface and is reflected from nanostructures.

Depending on the change in the external environment — increase or decrease in temperature, deformation, etc. — a wave traveling over the surface undergoes changes, from which we calculate the final value of the physical parameter.

We know the parameters of the original wave, we understand what affects it and how, and we also know all the mathematical dependencies. The most difficult thing in creating a sensor is its topological structure and technology of its formation. These are the most complicated calculations, modeling of all processes and, most importantly, the sensor must be unique in terms of its identification number in the measurement system, which means that everyone must have their own unique structure.

Interestingly, in the world surfactant technology is engaged in a relatively small number of enterprises. The whole problem, as I said, is very complicated calculations of the structure topology. The school surfactant was formed mainly in the Russian Federation. Now two schools of SAW technologies are developing in the world - ours and the American one.

The question may arise: how did we come to the surfactants? I will answer: from the radar. In radar units, many microwave devices with surfactant-based elements are in filters, resonators, delay lines, highly stable generators. And our specificity is the diversification of work in the field of the final product.

At the same time, the surfactant technology is essentially a piezoelectric. When surface acoustic waves are excited, a piezoelectric effect is used, when an electromagnetic wave, entering the antenna, through the piezoelectric transducer turns into an acoustic wave and propagates along the surface.

And we began work on surfactant technology relatively recently - in 2008 year.

- What are the products based on surfactant technology you produce?

- Already, we have serially supplied identification systems for various purposes. This may be inventory accounting and identification of people at the facility. The main advantage of SAW sensors over conventional semiconductor - the range at which we provide identification.

Our product in passive mode can identify an object, as I said, at a distance of 50 meters. For a semiconductor sensor, the limit is five meters.

In addition, the SAW sensor is highly protected. For example, quartz is resistant to external mechanical, temperature, radiation effects.

Our work was interesting in the field of agriculture - accounting and control of animals. Our surfactant sensors were the only ones sufficiently resistant to the aggressive environment of livestock farms. The question may arise: what is there that threatening? Everything is very simple: methane is released from waste. It destroys standard semiconductor labels very quickly. If I may say so, it just burns them out. Once a year and a half it is necessary to change the failed sensors, and they are placed in the animal's ear. So, you need to skip the whole herd to remove the old and put new ones. Not such a simple procedure. And when the sensors fail, control of the animals is instantly lost.

Huge potential of surfactant sensors in the construction of roads, bridges and tunnels. There are certain places where you need to frequently monitor their condition. Our sensor is built in for this, it does not require any wires or power supplies. We concreted it and forgot.

Later, when it is necessary to obtain the necessary data, a car with special equipment passes nearby and irradiates the sensor. And literally in seconds we get all the information. If readings are required more often, equipment is placed near the object. Information is removed when the customer needs.

What is the problem of the classic wired sensors used now? Take, for example, an object such as a bridge. He, as they say, "plays", the structures are shifted, albeit slightly. And the wires that are inside, over time frayed and fail. Replacing a classic sensor, even on a bridge support, is expensive and difficult. Looking for climbers, specialists who can correctly install and orient the sensor. And there are a huge number of bridges in our country.

Radar MMS measuring systems based on SAW technologies are used in helicopter engineering. Sensors are installed on the propeller blades, where it is necessary to take status indicators at certain points. Previously, to solve this problem was very difficult. The rotational speed of the screw is colossal, again you need to hold the wires to the sensors, and you can place them only inside the blade.

We offered a simpler option. Put the SAW sensor in the desired point of the blade, and no wires. The screw turns, and at the right time the device removes readings from the sensors using electromagnetic radiation.

Together with the helicopter builders, we are working to create a weight measurement sensor under the landing gear. We call this “high-precision weight measurement systems.” They are very important not only for helicopters, but also for aircraft construction.

In this case, it will already be a slightly different sensor, not passive, but active. Currently, we have a range of similar sensors that provide weight measurement in a wide range - from 0 to 300 tons with an error of only 0,02 percent.

- How difficult is it to produce surfactants? Do you need special equipment and where do you buy it, especially recently, when anti-Russian sanctions apply?

- Indeed, surfactant technologies require sophisticated ultra-precise equipment, but we found it in Russia and Belarus. The first thing that is needed is “clean” tight areas. Our company has one of the best acoustoelectronic zones where there are 7 and 4 classes. Currently, Radar Mms provides a topological standard for the production of products up to 0,35 microns. That is, our "drawing" on SAW-devices comes to 0,35 micron!

To achieve these indicators, a laser image generator was launched. It provides drawing on a crystal of "drawing" with the highest accuracy. The generator itself is located in the 4 class of hermozone. People work in masks, in gloves and at the same time they are in such an ultra-clean room, where one speck of dust falls on several cubes of air.

As for equipment for the manufacture of surfactants, it is partly Belarusian and, of course, domestic. Yes, we take something from abroad, in particular microscopes, but this is a small and not the most important part of production.

    Very informative material. There are many interesting things, only two questions arose. Systems will age quickly enough. It is in the military field. Nanotechnologies are no longer replacing "old" materials, they are running. How promising are developments now?
    And the second question. I do not want to offend our Belarusian friends, but are we not stepping on the "old rake"? The integration of production in the civilian sphere is excellent. And in the military? Are we going to deal with import substitution again?

      the answer is simple - if you want to be friends - be friends. if you want to be friends a la "American friends" - it is quite likely that missile defense and other similar nasty things will appear in the region of Vitebsk, Mogilev, Gomel.
      More and more often there are statements in the style of the Polish gentry from the deaf "zassenkau" (farmsteads). Is this already a tendency among worn-out snot or just sent Cossacks?

        Our trouble is that we approach the issue of friendship in our understanding, with the so-called. "Russian soul".

        We do not understand the Anglo-Saxon, or rather Protestant ideology, where the liberal self and everything else are at the core.

        They (USA) never talked about friendship - they talked about cooperation.
        But in connection with their Manifest Destiny, this is cooperation, well, how is cooperation in such a common occurrence among children, when one leader, aged 14-16, gathers a group of 7-10 year olds around him.

    I have deep and well-founded doubts that the sensors mounted on the propeller blades give accurate readings. I would say that they do not give objective data. Why? Because the ionizing effect of highly dynamic air flows is not taken into account. This means that in the so-called surface acoustic wave there will be a parameter of not only external electric. magnetic effects, depending on the complex of properties of air movement relative to the surface of the outflow, but also the complex of internal phenomena caused by directional EMF due to high centrifugal forces. Therefore, accuracy can be spoken of as desire, but not objective achievement.

      Well, there are sensors designed for biased data. Or the termination of data output is the function of the sensor. Another question, you can point out a dead end for competitors, on which spears were broken and time was buried. Let them storm ...

        There is a fundamental concept that the more comprehensive data the more accurate the probability that we are approaching objectivity. Then the gentleman below is in vain ironic. I seriously justify that working with big data is system knowledge that is at the level of interdisciplinary sciences. Therefore, I recall that the fractals of Maldenbrot are the most primitive structures, which are firstly planar, and not comprehensive. And secondly, they are static, and therefore this is only part of the solutions. The construction of the analysis structure at the same time in all coordinate axes is apparently not easy.

      At a minimum, you need to start with the fact that the modern idea of ​​a person about a wheel as a device with an infinite contact surface is absolutely true

      And more - fractals, more fractals .. and Maldenbrot
