"The cross-section of the radar is fifty times less": the Italian analogue of the Yak-130 equipped with a new complex

Among the advanced equipment possessed by the Leonardo M-346FA light combat aircraft, there is one that deserves special attention - a complex that provides low visibility of the vehicle.


M-346FA is able to deceive the "eyes" [surveillance system] of the enemy

- noted on Blog Before Flight pages.

As indicated, this complex can significantly reduce the cross-section of the aircraft's radar (RCS), which "gives it unique advantages":

Thanks to this kit, developed by [Italian company] Leonardo, the RCS M-346 is reduced fifty times.


Front-line aircraft are usually equipped with such systems, as this allows them to "escape the eyes of the enemy on the battlefield." As reported in the Western press, low RCS helps create stealth aircraft such as the F-22 and F-35.

It is noted that the complex is easily installed and dismantled from the machine. It is said to be the result of careful research and testing carried out by Leonardo in creating the aerodynamic shape of the aircraft, especially in the front, including the air intakes.

This demonstrates that the M-346FA was created as a fighter with all the capabilities typical of modern combat aircraft of the 30-ton class [...] Currently there is no other light combat aircraft in the world that can be less visible to the enemy than the M-346FA

- noted in the publication.

The M-346 is a Russian-Italian product. However, in the future, the paths of the creators of the machine diverged, in the Russian Federation it received the designation Yak-130, which is used as a training aircraft. Italian developers present their analogue of the Yak-130 as a multifunctional vehicle capable of effectively showing itself on the battlefield.

      no, they will not see.
      More precisely, the Yak will not see, he has no sight, he is purely training.
      And the Italian is a full-fledged combat aircraft.

        The Russian-language term is called the effective scattering area (ESR), as justly stated above. And the cross section of the radar can be interpreted as the diameter of the radar antenna in an airplane)

          Who told you that? The antenna can have an area close to zero, for example, have the form of a dipole, a piece of the thinnest highly conductive wire with a length proportional to half the wavelength of the irradiating radar, and when this dipole is oriented in the plane of polarization of the wave, the resonant reflection will be large.

        The term, which characterizes not a radar, but a radar target, cannot be called that. RCS - Radar Cross-Section - Radar cross-section of the target. A more or less literate specialist in the area under discussion, who should only retell the information received with such articles, should differ from a machine translator, and use the terms accepted in the technical literature of the target audience language. And in this case it is EPR - effective scattering area.

    this is fiction, not unique properties. The problem of reflecting an incident wave on an antenna strip has been known for a long time. But it is solved with the help of a frequency selective surface (CHIP), i.e. perforated electrically conductive foil, mesh with specially shaped cells or electronically or photocontrolled film

        there are two types of CHIP. First, the system is opaque during the passive state of the radar's own radar. At the beginning of its operation, the CHIP from a practically conducting state (screening mode) goes into a state with a very high resistance (“no screen” mode, operation of the radar).
        The second is when the screen is opaque for any frequencies, except for the frequencies of its own radar. That is, it is tuned to transmit electromagnetic waves in a narrow band of natural frequencies of the locator

          Of course, I am not an expert, but in connection with such a scheme for reducing the antenna RCS, certain questions arise.
          1. Is the game so worth the candle? Suppose that we have reduced the RCS of the radar antenna 50 times (which is doubtful). If my memory serves me, the detection range is proportional to the fourth root of the EPR. This means that the detection range of the antenna will decrease by about 2,7 times. Well, so this is the detection range antennas, not the entire plane. The entire aircraft will have more EPR than the radar antenna. Does this greatly reduce the detection range of the aircraft as a whole?
          2. Operation. Is there any data on how it is in operation? And then it often happens that some super-duper characteristics are bought due to complicated operation, which makes it very difficult to obtain those characteristics that are declared in the manufacturer's advertising brochures.
          3. Noise immunity. Frequency tuning. How does this fit with the operation of the CHIP? And then how can it be - pick up the frequency and crush it with noise. That's it, the plane is blind ...
          4. If the radar has started to work, then all these CHIPs immediately become useless. But this is a rather rhetorical question. It is clear that the RCS reduction is calculated for the case when the radar is silent. However, in terms of the totality of characteristics, what about the cost-effectiveness criterion?
          5. How much does the CHIP affect the range of its radar?

            Well, this is the detection range of the antenna, not the entire plane.

            imagine, for example, the RCS of the entire aircraft in frontal projection. 1/3 of this is the radar antenna, 1/3 of the air intake and 1/3 of everything else (midship, cockpit, edges, etc.). Accordingly, the radar, together with the air intake, contributes more than half of the aircraft's RCS. By decreasing the antenna reflection, we% decrease the total RCS.
            which makes it very difficult to obtain those characteristics that are stated in the manufacturer's advertising brochures.

            such things are first tested on ground benches in the BEC before getting on the plane
            Interference immunity. Frequency tuning. How does this fit with the operation of the CHIP

            the screen works on a physical basis. Therefore, this has nothing to do with interference.
            If the radar starts to work, then all these CHIPs immediately become useless.

            radar operation gives out the location of the aircraft. But it does not in any way contribute to the capabilities of guidance and target designation systems (except for the use of guided missiles on a frequently operating radar).
            However, in terms of the totality of characteristics, what about the cost-effectiveness criterion?

            the question is not clear
            How much does the CHIP affect the range of its radar?

            yes does not affect in any way. Reposition the radio source. In front of him is a screen with holes. What will happen? If the wavelength allows it to pass through the holes, then it just goes on. If the wavelength is longer than the hole, then the wave does not travel. That's the whole physics of the process.

    Twin brother to Yaku, M-346FA has evolved in a very promising direction! The well-thought-out design of the airframe, which gives a lot of possibilities, affects! By combining it with advanced avionics, the Italian have expanded the functional range! M-346FA is targeting a niche market where customers can be found! The Italians are great! It is a pity that the Yakovlevtsy did not follow a similar path! Could offer their own version of a lightweight cheap consumer suitable for poor countries! hi

    As a front-line combat aircraft, it is inferior to specialized representatives in all parameters except price, but the efficiency of a unit is made up of many parameters. For poor countries it is still expensive, for others the choice will be among the real representatives. Yes, plus drones that already cover a large chunk of the capabilities of attack aircraft and front-line fighters. Ambiguous aircraft in terms of prospects. Only if it is necessary to urgently replenish or supplement the basic backbone of aviation in a large-scale conflict (Israel, Russia, etc.), or create an IDB on the availability of aviation in countries such as Lithuania, Austria, etc.

      He was born this way. "Not a candle to God, not a damn poker." It did not fit into the training scheme adopted in the USSR (2 years "Elka", 2 years - UB of a specific type). Now expensive for the original and too "universal" for training and combat. And as a combat - generally in the area of ​​zero.

        So, after all, it was created without observing the terms of reference. His competitor in the competition was
        MiG-at,
        which TK is fully consistent. But the fate of the Yak-130 was better, they are now being purchased for the Army.

    I think we are talking about the side lobes. If we have increased the quality factor of the radar, then they are quite good fellows. Although most likely, they just crushed.

    In the original source (https://www.blogbeforeflight.net/2021/01/here-are-more-details-on-m346-low-radar.html) there is not a word about the on-board radar antenna of the Leonardo M-346FA aircraft and what or sections. The term RCS - Radar cross-section has no direct relation to either the airborne radar of the aircraft, or to the aircraft detecting radar, it is not the characteristic of the radar, but of the radar detected target and is correctly translated as "radar cross-section" of the target. In the Russian-language technical literature, a similar term is usually called EPR - "effective scattering surface" of a radar target. The article is about the usual methods of reducing the RCS of aircraft, changing the aerodynamic contours of the aircraft, especially in the front of it, including the air intakes. In other words, the decrease in the number and reflective properties of the so-called "shiny dots", which, as a result of the interference of reflections from different parts of the aircraft, give the lion's share of the resulting reflected signal. Mentioned in passing is DASS (Defensive Aids Sub-System), a system of auxiliary means of defense, that is, a system of a military aircraft that protects it from attacks by surface-to-air missiles, air-to-air missiles, that is, possibly anti-radar missiles and electronic countermeasures coupled with radar warning receivers to detect threats. One paragraph just casually mentions the armament of the aircraft. As requested the authors have given the above link to their original source.

    And for the local editors, the question is - where to send the bill for the work I have done for you?
