Developer: ROFAR technology allows replacing all the antennas on the ship with one locator

129
Using phased-array radio-optical antenna arrays (ROFAR) on a ship will reduce the weight and size characteristics of radio-electronic equipment by 5-7, RIA News report of the adviser to the deputy general director of the Concern Radioelectronic Technologies, Vladimir Mikheev.


Radiophotonics instead of electronics

The representative of KRET noted that “radio-phased phased antenna arrays will significantly expand the capabilities of modern communications and radars — their resolution will increase tenfold.”

“The carriers of this technology will necessarily be naval platforms, in particular, ship radar stations. Modern warships are literally hung with various locators and antennas, each of which operates in its own range. One locator with ROFAR technology due to its broadband can replace them all. We have an integrated assessment - we plan to reduce the weight and size characteristics of the equipment by 5-7 times ",
told Mikheev.

In the future, ROFAR technology can be used on submarines.

“It is possible that we will be able to look under the water, for hydroacoustics, for use on submarines, this technology is also being considered,” said the adviser.

        "Director General of KRET Nikolay Kolesov:

        - The scientific and technical project “Development of an Active Phased Array Based on Radio Photonics” (ROFAR) includes the creation of a new specialized laboratory and the development of a universal technology that will form the basis of new generation radar and electronic warfare systems. Nanophotonics is a promising scientific field, which will soon determine the vector of development of dual-use technology in developed countries. The latest technologies will allow us already in 2020 to create efficient and advanced transceivers, radar stations, electronic reconnaissance systems and electronic countermeasures, which will replace the existing line.

        The laboratory will create all conditions for conducting scientific research, including a cleanroom regime where the concentration of dust, microorganisms and chemical vapors is minimized.

        One of the main areas of research in the field of radio photonics will be the development and manufacture of a new generation of active phased antenna array (AFAR), which will reduce the weight of the equipment by 1,5–3 times, increase its reliability and efficiency by 2–3 times, as well as by dozens times increase scanning speed and resolution.

        Today, AFAR technologies are already widely used in the creation of airborne radar stations (radar stations) of modern fighters. At present, a radar station has been created for the MiG-35 Zhuk-AE fighter FGA and FGA35 with AFAR. It makes it possible to simultaneously track a large number of targets through electronic beam position control. The station is capable of detecting and capturing the enemy on water, land and in the air, recognizing its class, type and size, solving navigation problems and aiming high-precision weapons. "......

          .. Photonics is essentially an analog of electronics, using instead of electrons, quanta of the electromagnetic field - photons. These most widespread particles in the Universe, unlike electrons, have no mass and charge. That is why photonic systems are not subject to external electromagnetic fields, have a much greater transmission range and signal bandwidth.
          As a field of science, photonics began in 1960 with the invention of the first important technical device using photons - the laser. The very term "photonics" itself began to be widely used in the 1980s in connection with the beginning of the widespread use of fiber-optic transmission. By the way, in our country, the first development of such fiber-optic cables was undertaken by the OKB of the cable industry, now part of KRET.

          the mass of the emitter / receiver itself, as a radar unit, does not decrease, but increases.

          This is clear, since a dielectric (discrete or not not the essence) dome lens is added to the PMD

          and here cost analysis carried out during the development of a prototype waveguide CR shows that the cost of manufacturing a radar with GLA FAR-CL is relatively similar to the scanning system with a tetrahedral headlamp lower by 30%, and in the antenna part the gain can reach 50%.

          And of course, the 1 radar can replace several, since the lens, being a scattering one, allows you to increase the scanning sector of a flat antenna array due to the additional refraction of the rays, since each part of the CR acts as a prism, changing their direction ..

          which will give a gain in the mass of antenna posts.
          instead of 4 it will be possible 2




          Americans with the SPY-3 MFR went a bit wrong:

          And SPY-4 is the same in principle. Maybe they will switch to SPY-5 at ROFAR?

            A dome lens will only worsen performance in terms of accuracy and selection for noise and interference (from all directions to one headlamp).
            The slanted hexagon, plus the upper horizontal (7 PAR panels) - this is the ideal antenna system, with a high scanning speed and the maintenance of a large number of objects (your or someone else’s shell is also an object for correction or counteraction).

              What to do with radar fairing?
              On ANY LA?

              On beech trees?


              They poor fools do not know about this? (fairing is not KL)

              KU antenna reduction, placed under the fairing, is at least 0,5 dB, and the beam positioning error is up to 0,25 °, the reflection coefficient increases, the level of the side lobes (SBS) increases by 1 dB at the initial level of 20 dB and by 4 dB at the initial level - 30 dB.


              Cost Analysis [S chwartzman L., S tangel JJ The dome antenna // The Microwave Journal. 1975.], conducted during the development of a prototype waveguide CR, shows what are the costs of manufacturing a radar with GLA FAR-KL about similar in scanning capabilities to a quadrangular HEADLIGHT system 30% lower, and in the antenna part the gain can reach 50%.

              Slanted hexagon, plus upper horizontal (7 HEADLIGHT panels)

              These are convex (conformal) phased antennas (research began back in the late 1950s). Convex headlamps (VFAR) include flat headlamps and those built on their basis multifaceted headlamps as special cases.
              Here it is necessary to change the entire device (it is necessary not only to radiate, but also to accept / select)
              And the best will be a spaced conformal, exactly corresponding to the forms of the aircraft.

                What you “invented” has long been known: quasiconformal phased arrays

                Only for ground-based air defense systems, it is theoretically all the same, but better, like for a ship: hemisphere
                if you take into account the radar (hemispherical quasiconformal phased antenna array (KFAR))

                The faces of the truncated semi-icosahedron (emitters 2) are made in the form of pentagons and hexagons. An optimal embodiment is the antenna array (1) of sixteen emitters 2, identical in design: either in the form of six pentagons and ten hexagons with a hexagon in the center of the hemisphere, or in the form of five pentagons and eleven hexagons with a pentagon in the center of the hemisphere.

            It is impossible not to understand. that ROFAR technology or any other has a set of restrictions on the input data and on their processing. Working with big data is also associated with large energy costs for ensuring the operation of the system. Who understands what the problem is, no need to explain to him. At the current pace of development, everyone will very quickly align their positions with respect to each other. Breakthrough ideas are needed, first of all, at the fundamental level of solving the mathematical problems of receiving and processing big data, this time. These systems should work independently of energy costs — these are two. The adversary should not know that he is on the gun. which means that only one-way communication should be ensured, which means that the depth or density of the energy of e must be expanded. magnetic impulse. In addition, circuitry solutions should be transformed into bulk ones, and not on boards built in a linear principle. In general, I think that few people understood what was said.

          Neither a photon nor a fracture lens will help anything ..

Try to do something yourself with a head, find money for it and then find someone to sell it to. tired of narrow-minded. This is not trade, not IT, it is much more complicated and much more expensive both in terms of dough and in terms of working goals. In our country, now there is no problem in the dough, there is a problem in the brain - the brain market is just very small - those who go with the brains to work where they pay well or organize something themselves and who do not have it, they go to business and so on, maintenance, etc., etc. that is, having higher education, they are engaged in work at the level of a vocational school graduate or technical school. Why do not go to state-owned corporations and etc. enterprises - I already wrote a few brains above - just there go those who are interested in science and research more than their salaries, but that’s not all for everyone. The obvious thing is that their millions of stupid university graduates will come out of the Royal Sugar Loomonosov units and so on and so forth - but they will come out and they will receive all their fame and achievements in science at the expense of the state. Learn to work with the state, learn to milk it in the good sense of the word - yes it’s not easy, but it’s for this purpose only and it was created for you for your growth and development.

            There was a time, and it has already gone when university graduates were unloading wagons, V. Putin once said something like that, for the sake of words ... Not everyone was able to go into commerce, it's just not real. The Samara Polytechnic University at that time graduated several thousand engineers a year, imagine that if everyone became businessmen! The lack of demand for our industry in specialists, its collapse did their job, people retrained as much as possible or went to loaders, because the specialties of economists and lawyers are still priority. The industry has not developed and is still skidding, the defense industry does not count, there are also those bends, they are being driven by different figures in order to fill their pocket for the sake of their ambitions. My friend works as a simple adjuster of CNC machines, has a higher education, who will let him grow professionally if the bosses put his sorrow in the leadership in management ??? In our region, even in the region, it was previously possible to rewind a 250 kW electric motor, and now to do this you need to go to Moscow! And I live in the southern Urals, Orenburg region. Does this mean something to you ??? The industry is stagnant, nothing is developing except for some islands of the defense industry and all right! And if the industry does not develop, then the corresponding specialists are not needed, except for sellers of real estate, etc. When TNK came to the oil industry, we closed entire repair shops, turned lathes into the streets for sale, but got rid of unnecessary ballast. In the city, some shops are entire neighborhoods. Regarding your reasoning about the brain: whoever takes me into a state corporation as a simple engineer, you are closing the factories with one movement of your hand, without straining. Who needs my brains, but nobody, the whole principle of work sit silently do not be clever. In our electric workshop, with a higher education, I am alone, all other lawyers, etc. the bosses are the chief power engineer and the shop manager. What professional level can we talk about at all ?! And do not say that in search of a better share, you need to go somewhere else. The family and the apartment are not lying on the road.
            And again, no one is going to privately develop complex, high-tech production, no one needs this, and therefore no one needs specialists. They will invite me from abroad, but I’ll spread rot on my own, especially since education is in full prostration, undergraduates graduate from universities, and everything goes from school. Yesterday I just taught my boss how to format texts in Word, but they are afraid to talk about Excel in general. And yes, GDP and Dimka will not do anything similar, they have declarations, slogans and no more. God forbid that Putin does not "cross himself" and the country is not completely surrendered, he will become a liberal ... Sorry, maybe all this is not the topic, but nonetheless ... hi

      I would say, decades ago, back in the 90s, the whole theory and element base already existed to create “optoelectronic” (EHF range and above into optics) phased arrays. The only problem was the lack of sufficiently powerful and high-speed PCs to control these antennas, and without them all interest would be lost.
      The most interesting thing is that in mass production this technology is much cheaper and more profitable than traditional headlights, but it requires expensive technological equipment and scientific investments in production technology.

      Near-scientific, near-war and production management has a very strong braking effect, while politicians, it happens, also put sticks in wheels.

            "... In pulsed radio engineering there is an interesting pattern: the shorter the pulse, the wider its spectrum, the more frequencies it contains. The ultrashort pulse has frequencies from tens of hertz to gigahertz (10 <SUP> 9 </SUP> Hz). Its spectrum is indistinguishable from ordinary noise, from which, however, a transmitter signal can be distinguished.
            If the radio pulses are made very short, on the order of 500 picoseconds (1 ps = 10 <SUP> -12 </SUP> s), the electromagnetic wave as such will no longer be. Only a short burst (a) remains of it. To send a message in digital form, the “comb” of such pulses is modulated by increasing or decreasing the distance between them (b).

        No.
        Advantages:
        an increase in the scanning sector with a minimum decrease in gain (KU).

        (The decrease in the gain of the antenna placed under the fairing is at least 0,5 dB, and the error in the positioning of the beam is up to 0,25 °, the reflection coefficient increases, the level of side lobes (UBL) increases by 1 dB at the initial level of 20 dB and by 4 dB at the initial level - 30 dB.)
        For ROFAR fundamental is the limitation of the width of the working strip. It is caused, on the one hand, by an increase in the angular frequency sensitivity of the spacecraft relative to the flat headlamp proportionally to the CLCS due to an increase in the scanning angle by quasi-optical methods. On the other hand, for discrete CRs, this limitation is determined by the broadband of channels and emitters on the inner and outer sides of the lens.


        According to the data / Multifunctional cloth antenna arrays / D.I. Voskresensky et al. // Antennas. - 2006. - No. 9 /, the width of the working frequency band may exceed 10%.


        as defined by the United States Federal Communications Commission (FCC) (2002), ultra-wideband It is proposed to consider signals with a relative bandwidth of at least 20-25%

      In the first two letters "RO". So this is a common AFAR with all its problems, namely, it is difficult to pack the grating elements (and this is the antenna + amplifier + phase shifter) at short distances (for the 3 cm range, this is less than 1,5 cm) The complexity of the heat sink, since the efficiency of semiconductor emitters is still low. And the difficulty is to bring the signal from one master microwave generator to all the elements of the array. (for coherence)

      This is the most powerful "RO" and solves only the last problem. The microwave signal of the generator modulates the optical carrier, and is fed through the optical fibers (rot as you want) to the elements of the array, where the light is detected, turning again into microwave.

      The idea is old, successful, and it seems not ours. I don’t remember exactly where I first saw it.

        You are absolutely right that the idea is old and that means that it is not progressive. Rather, it can improve, but this is not a breakthrough technology. If we talk about real progress, then this can only be a technology for the single-vector reception of a radiating pulse from a moving or not moving object in the range of its individual email. magnetic radiation. And for this, a new elemental base is needed, which will expand the potential of the pulse energy density. There are no such shifts. In addition, fractal lattices have even more advantages than those shown in the photo, and which are built according to special mathematical techniques that rely on little-known number functions. In general, it is difficult to believe in the said advantages.

In other words, through processors it will never be possible not only to determine the development paths of the physicals themselves. events, but also coordinate them according to the level of dynamics and potential. Therefore, everything is carried out through mathematical methods that need to be solved only through the introduction of fundamental discoveries.

          This is not just replacing a waveguide with a fiber. Accepted microwave oscillation is transferred by each radiator at an intermediate frequency and after amplification with the help of a multi-channel light modulator (dynamic transparency), it is converted into fluctuations in the optical range.
          Further processing is carried out in the optical range using a system containing a laser, a collimator, lenses, apertures, optical filters, transparencies, etc.
          In this system, instantaneous analog processing of spatio-temporal information takes place. As a result, an optical image of the radar situation in the space in front of the receiving AR is formed at the system output in real time.
          Using optoelectronic devices, this image can be converted into signals for subsequent processing in a computer.

      Dome lenses can be continuous or discrete.
      To the first include homogeneous dielectric lenses, in which the thickness determines the introduced phase delay, or lenses with a fixed thickness with a relative dielectric constant, depending on the elevation angle.
      The second type represented by waveguide and coaxial-dipole structures. In this case, emitting openings or dipole elements are located on the inner and outer sides of the CR, and phase-shifting sections are located inside the shell. They can be either fixed or controllable, which significantly increases the cost of the structure, but at the same time expands the possibilities of scanning the beam.


      Demonstrator (full-featured radar): The dome lens consists of 8511 channels, made in the form of a hemisphere on a cylindrical pedestal, the diameter of the base is 1,93 m and the height is 1,3 m.

          applicable for long distances and ONLY the resulting / control signal, but no matter how energy from the central radio frequency source.

          Tk. Efficiency of an optical energy transmission line is about 50-70% (it is understandable for laser efficiency)

          Energy transfer through an optical fiber is possible only with a low-voltage transmission line with a voltage of the order of the semiconductor band gap, i.e., of the order of 1 eV.
          Modern optical fibers are capable of transmitting significant light fluxes of more than 100 W and have very small attenuation coefficients of the order of 0,1 dB / m


          And it can be (as you wrote above) acceptable for PFAR (1n large central radio frequency source (magnetron, klystron or TWT) and many emitting / receiving elements): BMEWS, BRLS-8B Zaslon, SCANFAR, (development AN / SPG- 59), and so on.
          Again the issue in efficiency

          For AFAR, which has a bunch (from 1000 to 3000) of PMD that combine a radiating element (or a group of radiating elements) and active devices (amplifying, generating or converting) is not relevant.

          They heat themselves (and they need to be cooled). And the power dissipation in the MMIC will not disappear.
          GaAs MMIC chips should work at low temperatures anyway.

          But the main limitation is the range of angles at which the beam can be deflected = not solve, without the principle that I described above or similar.

Other planets, images, the study of non-existent "black holes", the search for ephemeral "dark" matter - this is certainly good and interesting. Only practicality in this is somehow not enough. You can certainly argue and say that space technology and so on. But the annoyance, basically what is used in space, on the earth is not applicable (I'm not talking about heaters and stuff). Although I do not argue, science should develop in all directions. But this should not be profanity (an example of this is “dark matter” and the boson).

    Absolutely right! Even more than that, the radio-electronic equipment (EW complexes, FAR), which is already being produced for the needs of the army, is so perfect that rumors are circulating in British political circles about Russia’s cooperation with extraterrestrials. In full seriousness.

      Well, the ex-Minister of Defense of Canada, Paul Hellier, in 2014 seriously stated that the United States has been cooperating for several decades with two alien races. And in all, from 2 to 12 such races are engaged in our Earth. Can any of them be with us now?

    The abbreviation is new, it is not very clear what it means. And how they plan to create a WIDE AFAR - it is also not entirely clear. The receiving and emitting modules in such antennas are tuned to certain frequencies. Most likely, some nonlinear elements were used in the resonators. And signal processing has become more powerful. As a result, indeed, 3-4 antenna fields will cover the entire hemisphere. For ships - obvious savings, and weight, and money. Well, the lack of details is so secret ...

        No need to fantasize. To efficiently radiate, you need to have an antenna half a wave, a quarter wave, a wave. 1 Hz - a wavelength of 300000 km. Where did such a radiator fit?
        The article after the holiday, the man has not yet departed. Radio photonics is simply signal processing at light frequencies up to the antenna. Moreover, the antenna does not work at all at the light frequencies on these elements.
        Yes, the locator is stationary, scanning is carried out electronically and quickly.
        But I would still leave my locators additionally, because if you disable this locator, then everything will go blind.

            Do not write nonsense. A bunch of emitters gives the right power, but each emitter should work with good efficiency. There is such a thing as coordination with the emitter, which still needs to be done so that the radiation element does not overheat, that is, everything in the ether should fly away, and not the active element, but will burn.

    This will mean that the combat capability of a warship will depend on only one radar !!!! Amerikosy have already implemented all this in their much-praised IDJIS, which was easily extinguished by a container with a Khibiny system suspended under the wing of an old 24 SU.
    How not to twist, but the separation of the monitoring and guidance radar systems by frequency is a guarantee of protection against both electronic warfare systems and the elementary burning out of a "fucking radio tube".

        You don’t need to “read newspapers at dinner. The dog’s heart. The SS that worked according to the destroyer used the airborne system in active mode. And judging by some leaked rumors in the suppression mode, although if we compare the power of the destroyer’s power plant and it looks a bit fantastic for an airplane (suppression), but the fact that the control system was able to “blind” their system for a short time (if the memory doesn’t change their IDES) and at that moment they turned off the lights of their ship, the Bastion complex - this fact. Along the way, our control system collected the necessary telemetry, since this one was upgraded to the possibility of electronic reconnaissance.

          We’ve already disassembled a hundred times that it’s easier to blind the locator, because it emits a pulse and waits for a very small reflected signal. And the EW clogs its receiver with a direct, strong signal. The main thing is to guess by frequencies or send broadband radiation. So Khibiny, if properly configured, depends on the program, they will put out everything once or twice.

    The new technology will combine modern electronic equipment, such as microwave emitters and receivers, with optical elements - photodetectors, laser modules, etc. One of the main areas of research is the creation of a new generation of phased array antennas (AFAR) based on the principles of radio photonics.

    At present, radars with AFAR are used on various modern military equipment of Russian production, for example, on Mig-35 fighters, in S-400 air defense systems. Adding photon technologies to similar high-tech radars will dramatically expand their capabilities.

    In fact, in the Soviet Union radar stations based on phased array antennas were already operated. In particular, the air defense ring around Moscow consisted of them. True, they were 9 times higher than a 2,5-storey building. The effectiveness and reliability of these radars was simply amazing. But during the years of perestroika, they were decommissioned and disassembled. True, I'm not sure that is all. But those on which he was personally dismantled ...

    On the official website of KRET, this miracle of technology is announced a little more modestly. Namely, that KRET plans to conduct full-scale over the next 4-5 years laboratory research of this technology. Those. to serial samples of antennas is still very far away. In addition, such antennas have long been dealt with with varying degrees of success all over the world, and there was not and is not any special Russian technology that "has no analogues in the world".
    With promises to replace with one similar antenna all other antennas on ships, the situation is also not entirely simple. because ships always needed multi-band antennas to solve various tasks (navigation, detection and tracking of air and surface targets, weapon control, etc.).
    Therefore, there is a proposal not to throw caps in the air, but to wait when the promises of KRET are embodied in real products that are serially delivered for the RF Armed Forces. And life shows that from promises to their fulfillment there is a rather long way, which, moreover, sometimes runs into a dead end. And if in the promises there are references to nanotechnologies, which in the Russian Federation have been assigned to Chubais, then caution in forecasts requires even greater

The theory of analysis based on mathematical foundations is the ability to create not just new, but also optimal and rational devices and generally solutions.
