Concern "Vega" has finished testing the prototype ROFAR

The Russian concern "Vega" of the holding "Ruselectronics" has finished testing a prototype of an active phased antenna array based on radio-photonics - ROFAR. This was announced by the general director of the concern Vyacheslav Mikheev.

According to Mikheev, the new technology will reduce the size of airborne radars of aircraft and ships, as well as increase the accuracy and detection range of stealth targets. At the same time, it is specified that when using ROFAR, not a point will be reflected on the radar screen, but an image of the target, which is unattainable using traditional radar.

The active antenna array with a high-speed scanning system created within the framework of the project is built on the basis of distributed radio-photon transceiver modules, in which the original domestic component base is used

- said Mikheev.

Based on the results of testing the demonstrator created by the concern, we obtained results that allow us to talk about the prospect of using ROFAR as part of the latest marine, aviation and space technology, including radar surveillance complexes

- he added.

The general director of the concern also emphasized that the new technology allows integrating the pre-transmitter into the skin of an aircraft, ship or satellite, thereby increasing the radar field of view.

And why did they not add that all the filling is completely Russian, primarily microelectronics, and the entire electronic base? ??

You need to read the articles carefully:

There is a long way from application to deed. Domestic element base during this period of time cannot provide cardinal breakthrough technological solutions. It remains to be seen which modules are nevertheless designed on our microcircuits.

Of course they lie! 90 nm technical process mastering! And the bourgeois have already mastered the 7 nm technical process and are working closely with 4 nm

[vargo]

It's none of my business, but I would recommend that you update your information on Russia's capabilities to make its own microelectronics. Most of the claims against the country often arise only because little is said about achievements, and they are little sought after.
On my own I will add that yes, 7nm and 4nm are cool, but you also need to understand where they are needed and where not

[ltc35]

You may be right. I really hope for it. And since by the nature of my work I communicate with developers and know about problems from the inside, I can also talk about the possibilities of the domestic industry.

[Irokez]

On Mikron there seems to be a line from AMD at 90 or 65 nm, and it seems for a dozen years already. And the processors I7 or Razen in the military, no one will poke there other narrow tasks and reliability is needed as well as security.

[Cottodraton]

Military equipment is conservative and, as a rule, works on the most ancient technological processes, due to its greater resistance to the external environment. Five years ago I read a reprint of some foreign article. At that time, 90nm was not used in the military sphere ... therefore it is not critical

[Zaurbek]

"Ancient" sizes are also a different concept. For us 90nm, for Americans 24, for example
BUT yesterday GDP said that electronics will be revived.

[Cottodraton]

The ancients from the word "absolutely", that is, even up to nanometers

[vVvAD]

Only here is a mystery, how domestic components on a similar technical process have several times faster performance.
With our approach to electronics design and programming, even such a lag in the component base written above is fully compensated. But when we reduce the gap in the component base ...
By the way, we are going head to head in the development of quantum computers. Add the first paragraph to that, and it’s not funny at all - to the Americans.

[Dmitry Simakin]

You are right of course. There would be if it was really about electronics. But did you not pay attention to the fact that we are talking about radio-photonics? The fact is that the electron has completely exhausted itself, it is too inertial. Radio engineering goes over to the photon, which replaces the retired electron. And it’s not about optoelectronics, not about laser ranging. This is still scanning space with radio waves, but inside the systems for receiving, amplifying and optimally processing the received (and even radiated) radio signals, the radio signal is converted by optical methods immediately on the antenna. This allows us to radically expand the frequency range of the used sounding signals, the dynamic range of the receiving devices, the radar resolution, the speed of all its elements, and much more. Including completely new qualities of radio engineering systems ...
As for the foreign element base, it practically does not exist in radio-photonics. In contrast to the domestic one, which has passed not only preliminary preliminary design studies, but is already in technological pre-series development ...

PS A very long time ago (at the end of the 60s, or the beginning of the 70s - I don't remember exactly) in the magazine "Radio" (it was like that), as a teenager, I came across an article by one very clever engineer about laser information storage devices (CDs) - they were then only at the stage of experiments were ....... The essence of the article was remembered for a lifetime: "we are hopelessly behind (from the West) in the field of radio and microelectronics (!), but if we develop laser (and in these technologies we was a serious hit!) information accumulators, then we can (after skipping a certain stage) get ahead of the competitors and turn from "catching up" into LEADERS! .....

This is still a prototype (a working model, a prototype, or a rough implementation of a future system). Don't put it on the plane.
Much will depend on the cost of this radar. An example is AFAR. Although there may be another reason - overheating.

[Voltsky]

isn't that logical ?!
The CAR is already being installed on a number of NATO ships, and is slowly being tested.
Here your Rostec is also moving quietly, the future is closer than we think :)

[Kasym]

For some reason, they write little about the negative aspects of AFAR. With that overheating, they are forced to reduce the power of the AFAR to 30%, and this is already another "calico". It takes a very limited time to work "to the fullest", while reducing the speed. The Chinese are experimenting with air cooling. I somehow "dug" on this topic.
There is no doubt about it that work with ROFAR is going on in a stationary position. And how will it be at high speed, altitude, humidity, etc.? So there are enough questions and time is needed.

[Kasym]

The F-22 was taken out of production - why didn't they "optimize and eliminate childhood diseases of such a high-tech project"?
Submarine "Seawolf", helicopter "Comanche", etc.
I'm just asking myself a question - why didn't they launch a radar with AFAR in the Russian Federation? In addition to being very expensive (1 transceiver module for 1 USD), it gets very hot. It is even in Wiki - there will be time to read, informative. Moreover, retired American pilots complain of oncology - most likely it is from AFAR radiation.

This is not true.
There was the following. After slotted antennas, Western countries have chosen AFAR technology. We chose PFAR.
Each technology has its own small advantages. True, PFAR is half the price. And this is already a very big advantage!
That is, there is no lag. Quite the opposite. We have the following technologies: PFAR, developed by AFAR for MIG 35 and SU 57, and now there is also ROFAR.
And the west has only AFAR.

who turns it around?) I don't pray to anyone, I just try to reason objectively. The f-35 is truly an advanced aircraft in which the Yankees have implemented all their best and latest developments. Yes, at first it was raw, but gradually it is brought to the required condition.
Russian aircraft, even the latest ones, still do not have a radar with afar, and since the Russian industry has not yet been able to master it, it is suggested that the headlights are no worse, and even better. It's just that these stupid Yankees and Europeans, and now the Chinese are simply not in the subject, so they put afar in their newest planes, oh, fools

[Hagalaz]

Why are you chuckling about what you don't know? Below you have already written that the MIG-31 has been flying with AFAR for a long time. And for the Su-57 there is, it works.

[VO3A]

The F-35 has never been an advanced aircraft! Yes, individual elements, individual systems of this aircraft are really advanced, for example, the engine, the radar ... But the aircraft as a whole is the result of an unfortunate compromise, the victim of a multi-purpose approach and unification ...
He is an element of an advanced system - yes! But only pi_ndos have such a system! The Israelis are developing a truncated version for their small region, and no one else has such an information system in which the F35 can successfully demonstrate its capabilities ... All other countries buy an aircraft to work in the American system ... Without this system, the F35 is ineffective, this is an expensive and costly and not a universal aircraft. Yes, and judging by the results of combat use, it is not needed in such large quantities, but as a weapon carrier in the second line it is inferior to the 4th generation aircraft, which the States are starting to make again instead of this narrow reconnaissance, as it turned out ...

And how is the F35A / C / B worse than the F16, Hornet and Harier, respectively? + A10

F-35 is more expensive, often breaks down, capricious aircraft in terms of restrictions and requires systematic expensive maintenance. It was created as an aircraft for all occasions, to replace all the machines you listed above, but instead of doing your own highly specialized business, but good, like the machines of the previous one generation, it is used for all missions, but the performance of its duties is frankly at an average level. It is not a cheap and unpretentious workhorse like the F-16, the attack aircraft to replace the A-10 from it is so-so, clearly not an interceptor like Tomcat, dubious abilities for air superiority following the example of the F-15.

[voyaka uh]

It breaks less often than the F-16, in our practice. Easier to spot problems:
built-in diagnostic / prognostic system.
The inter-flight F-35 service requires more technicians working in parallel.
Israeli pilots are happy with it. The departing F-16s are not bored.

The F-35, on the other hand, easily finds passages in the air defense and enters the target without any

The point is that Israel chooses exclusively American technology, aircraft. Choice without choice, best of worst. The F-18 Super Hornet is a carrier-based aircraft for an aircraft carrier, and it's not very clever to use it on land airfields. The F-15 Silent Eagle was tested and was not accepted into service when Israel selected its aircraft. So sending Israeli pilots to the United States is just a formality. Decisions are made by politicians.

In Russia, some kind of heightened reaction to the F35. Just like a red rag for a bull.
In all flight parameters, it is at least not worse, and more often than F-16, A-10, F / A-18, AV-8B, in stealth and computing power it surpasses by a head. At a unit price, it is cheaper or the same as for the latest modifications of the F16 / 15/18, slightly more expensive than the Su 30, MiG 35 and cheaper than the Su 35. But for some reason it is super expensive and disastrous.
Even adequate people in the segment on the F35 blows the roof.

[3danimal]

Such an ideological attitude. And whoever disagrees with the "party line" broadcast in the media and "correct" (often yellowing) sites is an unpatriot, a propagandist and, in general, a spy

[Grazdanin]

Another set of stereotypes. Reliability was answered. The price of the F-16V Block 70/72 is higher than that of the F35A. Interceptors exist only in the Russian army (maybe someone else has remained in the cis), the F15 was not included in the JSF program, the A10 has not been engaged in "ground attack" for a long time.

[3danimal]

The price of the F-16V Block 70/72 is higher than that of the F35A

AFAR ZHUK-AM for Mig-35 at the request of the customer.

During the work of the international exhibition, it also became known that the Fazotron-NIIR corporation is completing the production of the first radar station with an active phased antenna array (AFAR) for MiG-29 fighters.


"Some MiG-29 customers want to see this station on an aircraft, the Russian military also intend to equip a MiG-35 fighter with it. As soon as the radar is tested, there will be funding and a contract. It is assumed that the whole process will be completed within about two years - we will manufacture about four samples, we will put on the plane and carry out tests, "- said a TASS source at the exhibition. According to him, a foreign operator of the MiG-29 will probably act as the launch customer. The new radar station with AFAR for the MiG-29/35 fighters was named "Zhuk-AM".

AFAR Squirrel for Su-57.

In the Scientific Research Institute of Instrument Engineering named after V.V. Tikhomirova (NIIP, part of the Almaz-Antey VKO concern) Izvestia was told that during flight tests the N036 radar confirmed the declared parameters. This radar will ensure the superiority of the Russian aircraft over any enemy, including the American fifth generation fighters: F-22 and F-35.

I have given you specific data on the AFAR tests above. You deny everything. It is not in my imagination that there are domestic AFAR, it is in your imagination that they do not exist.

Are there production planes with them? Is there a serial Squirrel?

The squirrel passed state tests as part of the Su-57. The first production samples of which are currently being built under a contract with the RF Ministry of Defense. So the serial AFAR Belka, which has passed state tests, is available and will soon enter service with the Russian Aerospace Forces as part of the Su-57.

What, are they really "under construction", have they seen it again? Already in August, all are not built in any way .. about the plan of 12 pcs / year

[Orange bigg]

For your information, what is a screwdriver assembly.
Screwdriver assembly is a SKD or SKD assembly (from the English Semi Knocked Down - "semi-disassembled", also ironically "screwdriver assembly") - a technology for assembling cars, in which the assembly site from the manufacturer is supplied with components completely ready for assembly, often already in the form of large nodes. A machine kit or a standard kit consisting of separate units, assemblies and parts for one assembly unit of equipment is supplied from abroad.
There is a serial screwdriver assembly. You just incorrectly put it. The production of the Su-57 cannot be, by definition, screwdriver, since no one supplies us in parts from abroad, so that we just assemble it here as a designer, that is, we just made a screwdriver assembly ...
With regard to serial production, it is being prepared, work is underway.

Don't worry about it. Very soon you will see the serial production of AFAR and ROFAR. The road will be mastered by those walking. The Russians are sawing for a long time, but sooner or later they finish. There are lots of examples! Suffice it to recall "Polyment-Redut" ... The main thing is that the ROFAR tests have ALREADY been carried out, this is a working innovation. There was little left to do. Aren't you glad?

However, a lot of new technology has been introduced recently, a lot is in development and is being prepared for introduction. The fact is that Russia does not give up what it started and sooner or later brings it to readiness. Compared to Western countries, they are not developing so many new things. And if they do, they also take a long time to do it. For example, they created the F-35 aircraft for 12 years, after which they began mass production. However, the plane is still unfinished, raw, with a lot of flaws. Also google the aircraft carrier "Gerald Ford" ... And this despite the fact that Western countries did not experience devastation in the 90s.

Maybe it was precisely the fact that the appearance of FOTAR was expected and explains the fact that so far only 12 Su-57 units have been ordered. Because equipping the board with new avionics immediately makes the Su-57 a 5+ generation aircraft

ROFAR technology assumes the use of RFM / D (radio frequency modulation / demodulation) of the main optical signals (photons).
A promising radar will translate the signal into a visualized version, which will provide an opportunity for additional analysis of potential targets. This makes it possible to implement, in particular, a wider frequency range in comparison with AFAR with an upper bar of about 100 GHz. which will enable domestic aviation facilities to receive all the necessary data on multiple and single targets at distances of more than half a thousand kilometers.

Another major advantage of ROFAR is the stability of the radar to the action of electronic warfare equipment. To suppress the operation of devices with ROFAR, a generator is required, which is at least 2,5-3 times higher than the functionality of existing generators for electronic warfare systems. So far, such a generator (at least in the version of placement on an airplane, helicopter or UAV) does not exist even in the version of promising developments.

Quote: Gorecc

Russian aircraft, even the newest ones, still do not have an afar radar,

This file is exposed by colleagues down the branch in their comments ...
Therefore, before you write, use your brains to begin with.
On my own behalf, I will say: our Kulibins simply stepped over the AFAR generation, creating a new avionics based on ROFAR. This is the only way to beat the Yankees. This is our unconventional answer to Uncle Sam - we get around our competitors on the corner by cutting off unnecessary corners!

Welcome to the world of smart military technologies. Instantly, ROFAR will determine what kind of target is in front of it. It will classify it. And who knows what next. Maybe the ammunition will pick up the right one. Or it may refuse to shoot (give a warning) that there is a civilian. Without waiting for visual contact with the target. ...

Read it yourself. The link below is the principle of operation of a radio-optical phased antenna array. I will give in the quotes the differences from the AFAR.

“Photonics is essentially an analogue of electronics, using quanta of the electromagnetic field of optical frequency — photons — instead of electrons. Radiophotonics is an integral part of nanophotonics, which studies the directional interaction of optical waves with nanostructures, while radiophotonics studies the directional interaction of optical waves modulated by radio frequency in specialized nanostructures and allows the creation of radio frequency devices with parameters unattainable for traditional electronics, due to the fact that photons, in unlike electrons, they do not have rest mass and charge, which gives potentially ultra-high speed and unique noise immunity.

ROFAR will allow us to see the plane located 500 kilometers away, as if we were standing 50 meters away from it at the airfield, its portrait in the video range. Moreover, if necessary, this technology will allow you to look into the plane itself, find out what people and equipment are in it, since the signal can pass any obstacles, even meter-long lead walls, thanks to the use of a wide frequency range, penetrating to various depths into the object. " KRET wrote that radio-optical phased antenna arrays will significantly expand the capabilities of modern communication facilities and radars - their resolution will increase tenfold. If a modern radar has a radiation frequency of 10 GHz, 3 cm with a spectrum width of 1-2 GHz, then for ROFAR this frequency can be from 1 Hz to 100 GHz at the same time. In practice, this means that ROFAR can provide a detailed, three-dimensional image of what is happening at a distance of hundreds of kilometers from it. For example, at a distance of 400 km you can not only see a person, but even recognize his face. “Unlike traditional radars, it will not be physically possible to drown out ROFAR with traditional electronic warfare means. The dynamic range of a photonic crystal is approximately 200 dB. A modern radio-electronic receiver, for comparison, has a range of 40 - 60 dB, and we use modern electronic warfare systems to provide a signal to the input of a radio receiver - 70-80 dB relative to its threshold sensitivity. Thus, the device that should receive the signal is taken out of serviceable state. Even after removing the obstacle, processes are still going on inside him that do not allow him to work. But on Earth there is simply no source of energy to supply a signal with a power exceeding 200 dB, so this logic in the case of ROFAR simply does not work. It can be confused by the so-called intellectual countermeasures, but that is a completely different story.

Kapets. Did the authors even study at school? Photon, by definition, is a quantum of electromagnetic radiation, on the basis of which all radars are built. Technically speaking, all radars use photons.

And about ROFAR is well written in the first paragraph of the Operator's message below (however, in the second paragraph - his usual nonsense).

It's just that the signals in such an AFAR are now generated by semiconductor lasers, transmitted over fiber-optic lines and converted into microwave radiation using special chips. All this makes it possible to significantly improve the parameters of the AFAR.

Radar efficiency increases from 30-40% to 60-70%

as a result, we can create a high-power radar. (Advisor to the first deputy general director of KRET Vladimir Mikheev):

recently, a year or two ago, there was a TV program,

Five years have passed since the announcement of the representatives of KRET (Concern "Radioelectronic Technologies") to begin work on a promising project related to the creation of radio-optical phased antenna arrays. Initially, the work was initiated by the FPI (Foundation for Advanced Research).
That is, since 2015, the media has become known ... how many years before that the theoretical basis for FOTAR was developed?

[KCA]

It is known about the beginning of work, I wrote that in the program they talked about ROFAR, how it is, what it is, what are the advantages, but did not say that the theoretical studies were completed and full-scale tests were underway

[Operator]

ROFAR - just ( ) conversion of an optical signal into a radio signal (and vice versa) directly in the transmit-receive antenna modules, which significantly reduces the weight, dimensions and power consumption of the rest of the radar equipment.

This technology allows the use of an ultra-wide spectrum of radiation, including millimeter, centimeter and decimeter waves. Radio imaging ("target image") provides millimeter-wave radiation, but it naturally spreads over short distances due to intense attenuation in the atmosphere.

[voyaka uh]

"... results that allow us to talk about the prospect of application
ROFAR as part of the latest marine, aviation and space technology, "////
----
Nicely said: "the results that allow SPEAKING
about the application perspective ... "

[KCA]

This is a very common expression in the scientific, technical and research environment, such as "the results of the study of the remains allow us to say that they belonged to a rich merchant of the 13-14 centuries", what is wrong? Have you ever seen / read such phrases?

[voyaka uh]

1) What is ROFAR - read very carefully, from beginning to end,
posts of users "Operator" and "mark1".
2) After reading, you will understand that ROFAR is a logical development of AFAR, its next
evolutionary generation.
3) There is nothing fantastic and cannot be: radio signals are weakened and scattered
but the atmosphere. And the shorter the waves, the stronger the losses.
4) For this reason, stealth is not particularly threatened by ROFAR.
At short distances, the new AFAR-ROFARs will cut stealth more accurately, but at large
distances, meter radars are still relevant.
Stealth will be dangerous network systems with strong computers and many AFARs,
exchanging data in real time.

[KCA]

I, in fact, did not write that this is a panacea for stealth, I wrote that, probably, due to the close appearance of ROFAR, they did not focus on AFAR, the point is in power consumption and dimensions, most likely you will not have to install water cooling and the entire ROFAR radar will replace the PFAR without time-consuming modifications to the aircraft

[Boa kaa]

ROFAR (as described in the first paragraph of the operator's post) is orthogonal to AFAR. Which, of course, does not contradict the fact that ROFAR will be AFAR.

The Russian concern "Vega" of the holding "Ruselectronics" has finished testing a prototype of an active phased antenna array based on radio-photonics - ROFAR. This was announced by the general director of the concern Vyacheslav Mikheev.

Vyacheslav Mikheev talks about the prototype, which means that it is in iron. This is really a hole!
With such a radar, both the Su30 and the Su35S and the MiG 35 will have 5+ generation, so that all air-fueling Russie immediately goes to the 5+ generation!

I'll add my 5 kopecks. Correctly wrote the Operator Today, 12:04 - indeed, there is nothing anti-scientific and "wunder-waff" in ROFAR.
Here is a very good interview, where a competent popular explanation of the principles of the ROFAR operation is given: https://tass.ru/armiya-i-opk/4442931, 27 July 2017, 09:06 "KRET has created an experimental model of a photonic radar for a sixth generation fighter":

Radio photon radar
As Mikheev explained, in a conventional radar station (radar), radiation is generated by electrovacuum or semiconductor devices, their efficiency is relatively low - 30-40%. The remaining 60-70% of the energy is converted into heat.
"In the new radar, the radar signal is obtained by converting the energy of a coherent laser into microwave radiation by a photonic crystal. The efficiency of such a transmitter will be at least 60-70%. That is, most of the laser energy will be converted into radar, as a result of which we we can create a high-power radar, "he said.
At the photon transmitter it will also be possible to obtain ultra-wideband radiation, which is physically impossible on a conventional radar.

In addition, I will add that the most important advantage of ROFAR is that since The microwave emitter is pumped with laser radiation, then you can supply power to the cells-emitters of the PA in the optical range, through the optical fibers. This dramatically reduces crosstalk and interference between modules.
And if they can also convert the signal from the radio range to optics directly in the receiver cell (perhaps performing digitization right there?), Then the input signal can be transported to the optics processing unit.
It will also make the antenna canvas easier and more flexible to adjust it to the contours of the body / wings / superstructures.

It is also correctly noted that ultra-broadband radio emission can be generated due to pumping by very short laser pulses. Those. one AFAR will be able to "touch" objects at different wavelengths, which significantly reduces the effectiveness of modern stealth technologies (coatings, surface geometry).
Now we have to move on to the use of "semi-passive" metamaterials and active means of suppressing the reflected signal.

I read an article on microwave laser generation in UFN2 back in the 90s. But then it was still the cutting edge of applied physics. 25 years have passed and knowledge has been transformed into an engineering solution, into devices. Thanks to the country's leadership (and the very one that I so often harshly criticize from a liberal standpoint) and Soros (and the same one whom the Stalinist patriots blame for the "collapse of everything") - they were able to save professors (many of our teachers were "Soros professors" and only because of this they were able to continue working in Russia!), scientific and engineering Schools that turned out to be able to prepare a new generation of "fundamentalists" and "applied people" - physicists, mathematicians, materials scientists and chemists, and development engineers, production workers who can transform knowledge into "hardware" and software.

[_Ugene_]

I understand that this technology will not bring any special breakthroughs in stealth detection, or does the ultra-wideband signal give some advantage in this?

[grumbler]

It just gives. "Stealth" technologies are still sharpened to reduce radar visibility in a rather narrow frequency range emitted by classical radars. The US signal is "smeared" in a very wide frequency range, and at least somewhere the irradiated object will be visible.
Therefore, the introduction of ROFAR can significantly reduce the effectiveness of generally accepted stealth technologies.

[grumbler]

The forum engine persists in auto-changing the abbreviation for UltraWideBand signal to "USA". Well, what's up?

[sivuch]

The forum engine persists in auto-changing the abbreviation for UltraWideBand signal to "USA". Well, what's up?
This is it from political correctness. Otherwise they will think that they are hinting at a name similar to Pakistan.
Thanks for the detailed clarification

[_Ugene_]

"Stealth" technologies are still sharpened for reducing radar visibility in a rather narrow frequency range

The narrow frequency range is decimetres and centimeters. What's your UWB signal? In the ranges of dm. and see this signal will be as ineffective as a conventional AFAR (the principle of generation is different, but um wave it is an um wave), and what remains? In meters, obviously, it will not work, the dimensions are not the same, but we get down to mm, IR, visible, UV radiation, etc. The detection range is too small in these ranges. And what's the bottom line? More efficient AFAR (efficiency is 2 times higher), with the possibility of conformal placement of antennas?

[grumbler]

I understand "ultra-wideband" in comparison with narrow frequency bands emitted by "narrowband" radars, where the current measures to reduce radar visibility (and possibly even ~ decimeters, meters) work effectively, https://www.radartutorial.eu/02.basics /rp21.ru.html

[_Ugene_]

Didn't you answer the question, how much of this ultra-wideband signal will make the breakthrough in stealth detection? Dm. and see, obviously, will remain as ineffective due to the sharpening of the stealth for these ranges

All radars are photonic. That's all.

[grumbler]

Formally, you are right. But, firstly, in classical radars they work more in a "wave" representation than they deal with photons-particles (although semi-natural microwave electronics are the basis of modern AFAR, this is, of course, "quantum electronics" in full growth). Second, the technology had to be given some sonorous name to emphasize the new principle of generating electromagnetic waves.

I wonder how many years will pass before production samples? 10-15 or more?
to stick around the Su-57 from all sides, it would immediately nullify all the advantages of stealth, oh dreams, dreams
I think if we shared this technology with the Chinese on the basis of joint production, then in a couple of years they would have put it on airplanes, but who will go for it, and they will bring it to mind for decades, and then everyone else will catch up

2) After reading, you will understand that ROFAR is a logical development of AFAR, its next
evolutionary generation.

The next development of AFAR is CAR, that is, an antenna array of digital transceiver modules. In CAR, the antenna directivity pattern, both for reception and transmission, is formed entirely in digital form. Now the digital method of forming the diagrams is partially implemented in the receiving channel of the radar with AFAR. For reception, the antenna array is divided into, say, 32 subarrays. Accordingly, there is a 32-channel receiver with an ADC. Phase distribution between sublattices is performed by a digital signal processor. This method, when received, makes it possible to form a fan of diagrams around the main beam in a limited sector. This is necessary for multi-positional radar, when one object emits, and another object receives the reflected signal.
AFAR with sublattices has been implemented in the west for a long time.

[yfast]

OK, morally we have already suppressed the F-35 and lowered it, now it remains to do it materially.

[We are for our]

Who else can explain in human language what kind of "radiophotonics" is, how does it differ from ordinary radar?

[grumbler]

Radiophotonics - the field of applied physics of semiconductors, lying on the border of semiconductor electronics (semiconductor electronics microwave), optoelectronics. What does the "physics of low-dimensional semiconductor structures" (so-called "quantum dots", "quantum filaments" and heterostructures) have, for example, to cellular communications? - this is the principle on which the element base works. Also here, radiophotonics - there is a basis for creating an element base for a new generation of radar systems.

[We are for our]

Also here, radiophotonics - there is a basis for creating an element base for a new generation of radar systems.

those. in fact, the "super-radar" itself supposedly works according to the same classical radar scheme at the same frequencies with approximately the same characteristics ?!
They tried to develop opto-electronics since the middle of the last century, even photton computers were made, but all over the world the direction was considered unpromising, and in our country (after all, Russia is a well-known leader in the development of electronics, right?))), Not only did they go their own way, so also forced the radar to work on photons?
Your deeds are wonderful, O Lord.

[grumbler]

Yes Maxwell's equations are still valid :)
The "radio-photon" element base will allow the radars to:
- to emit ultra-wideband sounding signals (this is a fundamental difference!),
- this is even greater flexibility in management (CAR, about which Igor Tikhomirov wrote today, 13:45 New)
- efficiency is significantly increased,
- solves many problems of electromagnetic compatibility,
- reduces mass dimensions.
Isn't that enough? This is a significant step in the development of technology.

Well, plus a little "advertising" - every innovation must be submitted in order to sell well.

[Avior]

From what the developers themselves usually say on this topic, in a simplified form, this is a way to control transmitting modules in an Afar antenna.
In conventional Afar, the modules are controlled by electrical signals, in the rofar module is controlled by a laser beam.
At the same time, according to the statements of the developers themselves, this method allows to significantly expand the range of operation of the transmitting modules in frequency, which makes it possible to obtain new properties.
But, to be honest, I have not seen any serious articles about such modules, and to what extent they have an extended range, although I specifically searched.
If someone gives a link, it will be interesting to read.

[grumbler]

There can be very little information about the modules for obvious reasons. But the principles of work in the open press are full of information, see the journals "Quantum Electronika", "Uspekhi Fizicheskikh Nauk", "ZhTEF", "Questions of Radioelectronics", etc. You need to search there, see articles of the second half of the 80s-90s. Just what scientists were doing 30-40 years ago, only now it has matured to a "product". For example:
L. D. Bakhrakh, A.A. Bliskavitskiy "Opto-microwave methods of forming the radiation of ultra-wideband antennas" // UFN, 1992, vol. 162, No. 2;

[Avior]

So prototype or demonstrator? Not entirely clear from the text.
Different things all the same.
A demonstrator is more of a laboratory model, and a prototype is a really working sample

[The eye of the crying]

Demonstrator, obviously. But, like the prototype, the demonstrator really works.

[Avior]

Demonstrator is a laboratory setup. Like a Hertz vibrator. Shows the efficiency of the principle.
And the prototype is a device that is actually working and fulfilling its functions.
There is a long way from demonstrator to prototype.

Quote: Avior

Demonstrator is a laboratory setup. Like a Hertz vibrator. Shows the efficiency of the principle.

A "demonstrator" usually means a "technology demonstrator". Those. demonstration of the efficiency of the technology, not the principle. And in Mikheev's quote, it is precisely the term "demonstrator", not "prototype" that is given, so there is nothing to argue about.

[Avior]

The question is what Mikheev means by technology.
If, in principle, the control of a semiconductor module by a laser, then from this to Rofar radar with the characteristics that Mikheev declares is not a short way.
They said something like that and about the other - that the speech in the layout is about the software part of the control.
It is difficult to understand what is true and what is not.

The question is what Mikheev means by technology.

In the late USSR, there were many developments in optoelectronic bullshit associated with the processing of radar and hydroacoustic signals. At the same time, the world has long been moving along the path of digital processing technologies. It is possible that an old development of the late 80s was exposed and they are trying to get money from the state budget for it.

[alien308]

In the late USSR, there were no materials and many modern technologies for the development of such equipment. The result was very low efficiency and large dimensions. More precisely, many materials already existed and many technologies too. But at the laboratory stage. They were not yet suitable for the product.

[gvozdan]

And what prospects open up for missile homing heads, compact powerful without overheating, resistant to electronic warfare.

[alien308]

At the expense of compactness and heat dissipation, they are cunning. There, as a source of energy, a laser, which has a low efficiency. We reduce consumption and heat dissipation in the antenna, and increase the pumping. But you can form whatever you want with the amplitude-phase time dependence of the pulses in a wide band. EW is tortured to score.

[grumbler]

It seems to me that we somehow missed the main detail of the radio-photon emitter under the intriguing name "photonic crystal". Dokin has several definitions, maybe someone will be interested.

Here's a popular article on photonic crystals from a serious author:
Ilya Polishchuk, Doctor of Physical and Mathematical Sciences, prof. MIPT, led. n. from. NRC "Kurchatov Institute"
"Photonic crystals will be the basis for a new generation of microelectronics", https://www.kommersant.ru/doc/1792642

"Photonic crystal" is a kind of so-called. "metamaterials", this is how they are defined
I.B. Vendick, O.G. Vendik in his review "Metamaterials and their application in microwave technology", LETI, 2012:

Metamaterial is a composite material, the development of which began at the turn of the XX and XXI centuries.
Artificial periodic structure in the composition of the metamaterial modifies its dielectric
and magnetic permeability, which allows you to control the laws of dispersion, refraction and reflection
electromagnetic waves in metamaterial. Theoretical and experimental research and technical
metamaterial applications cover a wide range of frequencies from radio waves to the visible
Sveta. In recent years, a number of laboratories have made great strides in research and application
metamaterials in the ultrahigh frequency range (1-100 GHz).

Introduction
Metamaterial is a composite material, the properties of which are determined not so much by the properties of its constituent elements as by an artificially created periodic structure from macroscopic elements with arbitrary sizes and shapes. In a very rough approximation, such macroscopic elements can be considered as
atoms of extremely large sizes artificially introduced into the initial material. Artificial periodic structure modifies the dielectric and
the magnetic permeability of the starting material. The developer of metamaterials has the ability to choose various free parameters (sizes of structures,
form, constant and variable lattice period of the elements forming the structure). One of the possible properties of metamaterials is a negative coefficient
refraction, which manifests itself with the simultaneous negativity of the dielectric and magnetic permeability of the material.

One of the pioneers in the study of metamaterials in the USSR was VG Veselago, see "On the formulation of Fermat's principle for light propagating in substances with negative refraction", VG Veselago. "Electrodynamics of materials with a negative refractive index".

Here is what A.Yu. writes about metamaterials and photonic crystals. Vetluzhsky in the article "Waveguide devices based on linear defects in metal electromagnetic crystals", Institute of Physical Materials Science SB RAS:

One of the interesting and promising areas of modern radiophysics is the development and study of the properties of photonic (or electromagnetic) crystals and metamaterials.
These terms are currently used to designate different objects with the same in many respects similar features. First of all, it is the periodic nature of their internal structure, which is an alternation of dielectric or metallic elements with different geometries and different electrophysical characteristics and which determines the peculiarities of the interaction of electromagnetic radiation with them. Speaking about these features, for photonic crystals, first of all, it should be noted that there is a band structure in the spectrum of electromagnetic eigenstates of such objects, which is expressed in the formation of frequency ranges in which radiation either freely passes through the crystal (allowed zones) or is intensely suppressed (forbidden zones) [ 1]. In addition, of great interest is the presence of a pronounced dispersion in photonic crystals, both frequency and spatial, which opens up wide possibilities for their very diverse practical applications [2]. As applied to metamaterials, the main interest in such structures is the unusual nature of reflections and refractions of waves at their boundaries, caused by anomalous (including negative) values ​​of the effective permeabilities of such structures, which, for example, are associated with possible significant changes in the technology of transferring optical images, in particular , overcoming the diffraction limit [3]. The fundamental difference between artificial crystals and meta materials lies in the scale of spatial inhomogeneities that form their internal structure - for the former it is comparable to the radiation wavelength, for the latter it is much less than it.

And here is the definition in the review by Yu. V. Gulyaev, AN Lagarkov, SA Nikitov "Metamaterials: fundamental research and application prospects", VESTNIK RAN, 2008, volume 78, no. 5, p. 438-457:

We recall that such artificial media are called photonic crystals in which, due to periodic changes in the dielectric parameters
(meaning the refractive index) the properties of propagating electromagnetic waves (light) become similar to the properties
electrons propagating in real crystals. Accordingly, the term "photonic crystal" emphasizes the similarity of photons and
electrons. Quantization of the properties of photons leads to the fact that in the spectrum of an electromagnetic wave propagating in a photonic crystal,
forbidden gaps arise, in which the density of states of photons is zero.

Due to the presence of a forbidden zone, but not for conduction electrons, but for E / M waves, photonic crystals are able to detect and generate EM waves, effectively converting "short-wave" EM waves (visible, IR) into "long-wave" (microwave) and vice versa.

All this shows that ROFAR is not a "crashed flying saucer technology", not a "miracle weapon" and not a panacea, but a natural result of many years of fundamental and applied research and engineering developments.
