    Game-changer: Scientists at the National Research University of Electronic Tech “MIET” (Moscow, Russia) have created a new radar remote sensing device for aircraft and spacecraft. It can capture images regardless of lighting, weather, the presence of clouds, or tree crowns.

    "It is known that the lower the frequency range, the greater the penetrating power of the wave, so our radar can survey not only through clouds and fog but also under foliage” it can accurately scan the state of soil, ice, etc

    If this gets mounted on combat drones-it’s game over

    New means of reconnaissance: radar station "Yenisei" entered the Russian army

    Russian Aerospace Forces received a radar with unique characteristics for equipping air defense systems. At the end of April, the Yenisei radar was adopted by the Russian army, a high-ranking source in the Russian military-industrial complex told Gazeta.Ru. The newest station can be part of the S-500 air defense system, although in reality this locator is a much more universal reconnaissance tool.

    The Yenisei radar station, which entered service with the Russian army, is designed for continuous operation for a long time. For example, the S-400 Triumph radar systems (a command post radar system and a multifunctional radar station of an anti-aircraft missile battalion) were not originally intended to function for such a long period, since anti-aircraft battles and battles do not take place for long hours and days.

    It is this feature of the Yenisei that makes it possible to receive reconnaissance information for a long time, which is important for the means of conducting radar reconnaissance. At the same time, the operator's error factor is practically excluded - the radar works, as they say, in full automatic mode.

    Yenisei is a fully digital locator, its antenna is an active phased array. In addition, the radar is an active-passive device, it can conduct reconnaissance and detect air objects and issue target designations to air defense fire weapons even without broadcasting. That is, "Yenisei" has the functions of conducting electronic intelligence.

    In particular, information on targets from the Yenisei is issued to the multifunctional radars of the S-400 and S-500 anti-aircraft missile systems.

    This year, a contract will be signed for the supply of the S-500 air defense system, since all the components of the system are already ready. As for the S-400 air defense system, the Yenisei (along with the 96L6 all-altitude detector) is already included in this system.

    The Yenisei locator is equipped with remote posts, which allows it to successfully deal with jammers. For example, the success of the US Air Force's actions in many local conflicts was ensured by the fact that practically all air defense systems of Washington's opponents were suppressed by powerful and well-organized interference.

    But this does not apply to the Yenisei. The higher the interference intensity, the better the locator ties up target tracks and more accurately gives target designation to air defense fire weapons. So with the adoption of the Yenisei by the Russian Aerospace Forces, the United States, one might say, lost this trump card.

    Another feature of the Yenisei radar is that the radar can operate in a sector (recall that most radar reconnaissance equipment operates in a circular view mode). This characteristic allows the radar to successfully issue target designations for ballistic missiles.

    By the way, the 96L6 all-altitude detector (VO), usually attached to the S-400 air defense system, cannot work in the sector.

    The characteristics of the "Yenisei" interested the leadership of the anti-aircraft missile forces of the Russian Aerospace Forces. So, the radar complex (RLK) 92N6 of the command post of the S-400 anti-aircraft missile system operates "round-the-clock". But it is the continuous and long-term work of the Yenisei in the sector that will sharply increase the effectiveness of anti-aircraft missile defense against ballistic missiles in missile-hazardous areas. Therefore, in the anti-aircraft missile forces at the positions of the command post of the S-400 air defense system, two locators are installed at once - the standard 92N6 S-400 radar and the Yenisei radar.

    In addition, the Yenisei “sees” well and accompanies its launched anti-aircraft guided missiles and can very accurately determine whether the target has been hit in the event of a meeting. This feature of the locator really liked the leadership of the anti-aircraft missile forces of the Aerospace Forces. Now, with the help of the Yenisei, they can assess the effectiveness of the anti-aircraft missile units.

    "Yenisei" provides the issuance of target designations for hypersonic targets.

    And this system has another remarkable feature. For example, the missile of the Iskander-M operational-tactical complex first rises to a great height (about 100 km). Then, on the descending part of the trajectory, it begins to actively maneuver. This makes it almost impossible to intercept it.

    Moreover, on the way to the target, the Iskander missile releases carbon threads, which leads to a complete illumination of the enemy radar indicator screens, that is, there is such an abundance of false targets that any effective operation of the enemy's anti-aircraft missile systems on such missiles becomes simply unrealistic. ... In the United States, they have not developed any effective method of confronting the missiles of this complex.

    Yenisei, on the other hand, “sees” such targets, can steadily accompany them and issue precise target designations on them.

    In addition, Yenisei is able to effectively combat atmospheric phenomena, the so-called "angels". They arise mainly over water surfaces and cause a strong illumination of the indicator screens (in the form of a large number of false targets) of both detection radars and missile guidance stations. In particular, the Chinese came face to face with them after purchasing the S-400 air defense system and placing their starting positions near water surfaces. Domestic experts have made effective protection (by various kinds of algorithmic tricks) and from "angels", including on the Yenisei radar.

    Also, the Yenisei is equipped with built-in state identification means, both domestic (the Guardian system) and NATO MK-12 (the latter may be of interest to foreign customers). In addition, the locator also has a secondary channel for operation in the EU ATC (unified air traffic control system) in the range of 1030-1090 MHz. This allows the Yenisei to have complete information about the civilian aircraft currently in the air.

    The Yenisei radar is highly maneuverable. The coagulation / deployment time does not exceed 5 minutes.

    To increase mobility, outriggers (outriggers), which, for example, have, for example, VVO 96L6, were removed from the Yenisei. Mechanical "paws" for leveling at this radar remained, but they are already being put forward in a rut, without removal.

    Yenisei detects airborne objects at altitudes of more than 100 km (on the border of space and air space), at ranges over 600 km, steadily accompanies them and is a universal and multifunctional tool for detecting a variety of airborne objects and issuing precise target designations to fire weapons air defense.

    The name "Yenisei" has already been carried in the past by a mobile two-coordinate VHF radar station of the P-12 radar. This locator entered service with the radio engineering troops (RTV Air Defense Forces) in 1956 and for many decades served in the field of protecting the airspace of the USSR.

    I would say Iraq and Serbia and most other places they have attacked, they have started with jamming and during that jamming attempted to destroy major radar sites and communications centres and HQs.

    During Desert Storm they used Apache helicopters to sneak in at low altitude to destroy large radars to clear the way for cruise missile and stealth aircraft attack.

    That's why you need Sosna-R, 57mm AA gun and manpads in huge quantity. They are totally immune to radar jamming.

    That is it , they confirmed it themselves, modern meter wave radars hace gotten improved resolution and can perform stand alone tracking. Although it was obvious from the start, the fact that they confirmed it themselves means some folks can finally shut the **** up about meter wave resolution limitation.


    And to think that some People are saying that even the higher frequency wing slat radars would be lacklustre.....

    "The type of target will no longer matter": the head of the RTI Systems concern - on the development of radio photonic technologies for radars, June 26, 2021, Alexey Zakvasin.

    Research in the field of radio-photonics, which is now being carried out in Russia, will significantly improve the capabilities of radar stations. Yuri Anoshko, General Director of JSC Concern RTI Sistemy, spoke about this in an interview with RT. Radiophotonics is a field of physics focused on the transition to the optical range of information processing. The concern's specialists, in cooperation with other Russian enterprises and research centers, expect to radically increase the speed of radar data processing, enhance noise immunity and reduce the energy consumption of modern and future radars.

    - Yuri Gennadievich, practically nothing is known about radio photonics to a wide range of people. Could you explain what this area of ​​modern physics is studying?

    - Now there is a generally accepted, but not entirely correct interpretation. It boils down to the fact that radio photonics is a technology for transmitting information inside a radar station via optical channels, that is, converting data from the radio band to the optical one. Many modern radar stations already use such a scheme.

    The optical range is characterized by a high level of protection against the effects of various suppression means. It can be unambiguously stated that the throughput and stability of such a channel is higher than that of traditional schemes.

    However, in its pure form, this cannot be called radiophotonics. In fact, it assumes the maximum allowable transition from microwave (ultra-high frequencies. - RT ) to the optical range both in the location and in the information processing segment.

    - Can we say that radio photonics has become a trend in modern science, a popular field of study?

    - The development of science and technology always follows the same scenario. First, a hypothesis appears, which is either confirmed or not. If everything is in order with it, then it goes into the field of scientific research, and those, in turn, flow into experimental and applied research. At present, we are only at the stage of confirming the viability of the existing scientific hypotheses in the field of radio photonics.

    - Nevertheless, is it possible hypothetically to create a radio-photon station and how will it conceptually differ from the usual radar?

    - In my opinion, the issue of creating a radio-photon station is overly advertised in certain circles. Now Russia and other countries are only moving in this direction. No one yet knows how to build a radar (radar station. - RT ) solely based on radio photonics technologies.

    Today it is appropriate to talk not so much about the creation of such a product, but about the development of a number of technological solutions and their subsequent integration into modern and promising radar stations.

    In our research, we focus on the transfer of radar information from the radio to the optical range, where, as it is assumed, the data will be mainly processed.

    - What will the technology you are talking about give in practice?

    - The possibility of switching to the optical range opens up very great prospects. In practice, we will be able to develop radars with significantly improved characteristics. First of all, we are talking about a serious increase in the volume and speed of information processing by radio-photonic optical processors.

    It will also reduce the weight and dimensions of the radar, reduce heat generation, and enhance noise immunity. In general, we will get a new quality of radar information processing. Without progress in this field, it is unrealistic to count on significant success in increasing the potential of radar detection equipment.

    - Will the radar range increase with the introduction of radio-photonic solutions?

    - It is difficult to unequivocally answer this question, since the range indicator depends on many accompanying factors.

    - Will such a radar detect hypersonic aircraft? This question now worries many, including Russia.

    - If we are able to implement a quantum locator in its original understanding, then the type of target will no longer matter. In this sense, we will be able to see any air objects and promptly process information on them.

    It will be possible not only to accurately determine the coordinates of targets, but also to display (on the radar screen - RT ) an image of this object, which, of course, simplifies identification and improves the awareness of decision-making centers.

    - One gets the impression that radio photonics began to develop as a way to correct the shortcomings of existing radars. What problems do modern radars have?

    - This logic is not very correct. It is worth talking not about the shortcomings, but about the objective limitations that exist in the microwave range and are associated with the physics of this state of electromagnetic energy. But two major problems, which I mentioned, are solved by radio photonics - this is a significant increase in noise immunity and the throughput of information streams.

    - What about energy consumption? It is no secret that modern radars are extremely energy-intensive, which a priori worsens their performance.

    - You're right. But a large amount of power consumption is an inevitable necessity to ensure the normal operation of modern locators. A powerful radar station consumes a lot of electricity, and it will not be possible to change the situation with the help of the usual technical solutions. In this regard, the optical range just allows you to achieve a significant reduction in power consumption.

    - In 2018, the RTI Systems website announced the creation of the first experimental radar with elements of radio-photon technologies. It was emphasized that the appearance of such a product made it possible to confirm the possibility of using radio-photon technologies in radar. At the same time, it was noted that the radar had a lot of shortcomings and limitations in its use.

    - Yes that's right. We have proven the fundamental possibility of integrating these technologies into radar systems. To obtain further large-scale results, research is required on the development of nodes for transmitting information to the optical range. What, in fact, our concern is doing.

    Naturally, we do not work separately and we are building interaction with leading enterprises and research institutes in Russia, which have gained some experience in the field of research and implementation of radio photonics technologies into practice.

    The center of concentration of our competencies is the site of the design center for radio photonics on the basis of the Academician A.L. Mints.

    - Is it still possible to predict that the creation of a full-fledged radio photonic radar is a prospect for the coming decades, since it is necessary to solve too many complex problems?

    - As I already noted, the issue of creating a prototype of a full-scale quantum locator is not on the agenda. It makes no sense to talk about any timing of the appearance of such a product yet also because many scientific and technological solutions will need confirmation of the right to exist for a long time.

    Moreover, it should be borne in mind that the development and operation of a radio-photonic radar will entail the creation of a virtually new industry - it will be necessary to establish mass production of a wide range of completely new components, an elementary component base, fundamentally different systems and assemblies.

    On the one hand, this opens up new horizons for the development of the high-tech sector in Russia, on the other, it is a resource-intensive and not at all fast process that will require the concentration of significant competencies and finances.

    - Do you have an understanding of the stage at which projects in the field of radio-photonics abroad are?

    - Earlier in the public space of foreign states there was a lot of information about the development of these technologies, but at a certain moment this flow stopped. This indicates that, in all likelihood, a certain level of development of radiophotonics has been reached abroad. The closure of information probably indicates that research has migrated to the practical plane.

    - What place does Russia occupy in this eternal competition with the West?

    - In order to compare the achievements of Russia and foreign states, you still need to have more complete information than what I have. However, I have no doubt that domestic science and industry are not lagging behind the West. Another question is which way of technological solutions will be the most correct.
