China announced the creation of a radar capable of detecting invisible aircraft

89
The North Industries Group, a Chinese corporation, conducted tests of the newest radar in the area of ​​the city of Chengdu, which is reportedly capable of detecting stealth-made aircraft at a great distance.

Hong Kong South China Morning Post reports that the principle of operation of the radar is based on the generation of terahertz radiation, or T-rays. Such rays can penetrate deep into the surface of composite materials and are widely used in industry to detect hidden defects in products.

Until recently, the use of terahertz radiation for military purposes was limited to low productivity of generators. Also, T-rays cannot be produced by radio or optical devices.

However, it is argued that the current device is able to generate stable continuous radiation on average in 18 W and terahertz pulses with a maximum power of 1 megawatts. This power will be enough to detect the radar absorbing coatings of the F-35 fighter. However, while the radar remains too cumbersome and can not be installed on airplanes.

Using such a radar will help the Chinese military to find at a considerable distance such American aircraft as the F-22 and F-35. Chinese media differ in estimates of the distances at which stealth can be detected: the indicator is more than 100 km, but some publications report on 500 km.

Recall that in May, the Chinese media wrote about the successful tests of a new generation of missile defense system capable of intercepting ballistic missiles, reports On the eve of.

        IMHO, the “Americans” themselves have long had no illusions about the “invisibility” of their “stealth.” At one time, the “invisibles” of the F-117 were knocked down by “needles” and old C-125s. More modern F-22s and F-35s are no better in terms of “invisibility”.

          No one can judge the quality of the Chinese army.
          Yes, their elite units are SURE to give way to the elite units of those countries that regularly fight and at the same time have enough funds to equip their army well. But this is only due to the lack of experience that can be gained quite quickly.
          But the bulk of their troops - NOBODY can say how effective it is. But it is well equipped.

      Terahertz (submillimeter) radiation is located between infrared radiation and microwaves, in the range from 1 mm (300 GHz) to 0,1 mm (3 THz).
      They hiked a very powerful “flashlight” there, I wonder how this echoes our developments in the topic of the latest radars?

      I decided to leaf through the literature a bit, there are really a lot of terms, but I noticed what a thing.
      Recently, linear accelerators and synchrotrons have been used as THz sources. The paper presents a pulsed source of THz radiation of high power (average - 20 W, and at the peak - ~ 1 MW).

      Wow! How many such pulses can a radar give?

      Arithmetic is simple. Known average source power P = 20 watts. and pulse power p = 1MW = 10 ^ 6 watts. Next, we set the pulse duration t = 1 μs = 0,000001 sec. We consider the number of pulses N for 1 sec with an average source power of P = 20 watts. N = P / (pxt) = 20 pieces / sec. If we reduce the duration of the probe pulse of the locator, for example, a hundred times, we get 2000 imp / sec.

      This is pulse power. Roughly speaking, if you emit a pulse lasting a microsecond with an energy of 1 J, the pulse power will be just 1 MW. We carefully read the article:
      However, it is argued that the current device is capable of generating stable continuous radiation of an average of 18 W and terahertz pulses with a maximum power of 1 megawatt.

        Everything depends on the distance, the plane, its “abstruse” form, cannot do completely invisible. Stealth reduces the range of its detection, no more. Another question is how much?

                    Yes, the main missiles there are 48N6E, 48N6E2, 48N6EZ, 9M96E2 but you can also charge 40N6E.

                      The detection range of the aircraft is equal to the fourth root of the change in the magnitude of the EPR.
                      Accordingly, the EPR strategist has about 100kV. m. EPR stealth let's say it will be 1Q. m. (actually less) Corent 4th degree out of 100 is 3.16
                      That is how many times the range of the radar will decrease for such a purpose in an interference-free environment. So from 600km it is already less than 200km. Discount that the 48N6E2 missile on board has a worse radiation receiver than ground-based radar. Get even sadder data. And with interference, it will become completely sad.

                      the planning bomb was an example of cheap ammunition. Although such a range is quite enough. I repeat once again. The maximum range of destruction of air defense systems is not at all equal to the real range in combat conditions. Nothing prevents the attacking aircraft from entering the affected area and turning it away after launching an air defense missile. Or go to extremely low altitudes. The earth then turns round, as not so long ago the Russian military learned, the radar beam will not be able to illuminate the target at such a range. And all S-400 missiles are semi-active.

                        You wrote that this is the range of defeat. In this case, it will be the detection range under ideal conditions. Which is not the same thing at all.

                        And what is the difference if everything rests on the range of an air defense missile system? The target will be detected over 200 km, captured and will be launched. In any case, those missiles that are now, they will get 200 km stealth. Moreover, maneuverability is not so hot and there is no speed.

                        the planning bomb was an example of cheap ammunition. Although such a range is quite enough. I repeat once again. The maximum range of destruction of air defense systems is not at all equal to the real range in combat conditions. Nothing prevents the attacking aircraft from entering the affected area and turning it away after launching an air defense missile. Or go to extremely low altitudes. The earth then turns round, as not so long ago the Russian military learned, the radar beam will not be able to illuminate the target at such a range. And all S-400 missiles are semi-active.

                        Ok, then max. range of stealth weapons is not equal to range in combat conditions wink . And he can turn the plane away, but leaving the rocket is far from a fact. A radar illuminates a stealth type target, as we found out over 150-200 km. Do not be ironic about the intelligence of those people who created these systems. Agree, they know that the earth is round and have provided their countermeasures in this regard. wink . And whoever blurted out this stupid smear about the "roundness" and away we go. This has nothing to do with the real attitude of affairs. In addition, 9M96E2, 9M96M for 120 km and 9M96E for 40 km have active homing. Like 40N6E at 400, which in your opinion does not exist.

                        Partly agree, but only partly. Maybe it’s not a matter of range, but ... The T-90 has a completely different tower than the 72B, the engine and the OMS. And this is the floor of the tank. BU was a factory long name, changed to a new index, because the tank was very different. The Su-35S has different engines, a completely different avionics, unlike the SU-27. But life is already Su-27M (which was offered for sale under the Su-35, but it's not a su-35С which is riveted today) and BM considered it long and changed the index to SU-35S. S-400 was developed on the basis of 300, but still it is a different complex, I am not strong in air defense systems, I don’t know what exactly differs, but this is not only a matter of commerce. Russia did not push him to the market. Since this is still a fresh, secret prodigy. Few people have it now, and they will be actively selling only after the creation of the S-500. hi

                    The normal target for the S-400 is from 2 m2 EPR and above.
                    This is enough to direct missiles and hit all 4th generation aircraft.

                      It is difficult to imagine how an airplane in a projection from below can have an EPR of 0.001 m2. When the plane flies over the radar, the EPR will be measured in meters, it is in the front projection that the EPR of 0.001 m2 is declared. (in ideal conditions, in practice, there will always be more EPR, because the plane flies from above and the ground radar irradiates it not from front, but from front to bottom). But the Patriot’s radar doesn’t see him at all, and why I already explained.

                      Understand that I in no way diminish the benefits of stealth technology. Moreover, I believe that no modern ground-based air defense (without the support of the aviation component of air defense) has a chance against stealth mass exterminating.-Bombers.
                      But there is no need to bring the situation to the point of absurdity. No technology can make a plane in the lower projection inconspicuous - a huge plane of several tens of square meters. meters, it is impossible to hide it only with the help of a radio-absorbing coating (otherwise it would be possible to make a stealth from any 4th generation), the lower projection at the level of several square meters will reflect. meters. Therefore, stealth pilots do not break through ground-based air defense anyhow, they try to turn the nose of the plane to the radar, if possible as little as possible, and they will never set up a huge lower plane.
                      Therefore, statements like - the modern AFAR does not see the F35 flying over it cause only a smile. If this information is really presented like this, then this is clearly a manipulation.

          the accuracy and range resolution of any radar depends on the width of the signal spectrum. m meter and centimeter they are about the same. But to reduce angular errors in azimuth and elevation in the meter range, you have to increase the size of the antenna. The errors in this case are not much larger than in radars with a shorter wavelength. But if you need ultra-high accuracy at all, then you can place the radar away from the air defense system, then the error ellipse will be at an angle and the relative angular accuracy will definitely be higher than that of the radar in the cm range, provided it is located on the air defense position. soldier

    Do you want Israel to adjust its financial budget, reduce their costs of eastern militarism? It is still their business to buy a large one for 5, or a small one for 3.

    They hiked a very powerful “flashlight” there, I wonder how this echoes our developments in the topic of the latest radars?

    Rather, a heavy-duty radio fault detector, judging by the article.

      Their antenna, to the pain in the eyes, resembles a set of flash lamps in a bulb with a reflector and filter.

    The terahertz radiation wavelength is from 1 mm to 0,1 mm, the maximum propagation distance in the atmosphere is 1 (one) km due to absorption by water vapor laughing

    Terahertz radiation is used to detect objects under human clothing or to inspect rooms through walls at a distance from 1 to 10 meters.

    Persian is not able to master what he read ... that's what is written in that propaganda article ..
    "... The flight range of the 48N6E3 and 48N6E2 missiles, which are most often equipped with launchers, is 250 and 200 km, respectively. The main know-how of the S-400 is the 40N6E missile, which, according to unconfirmed information, is being improved by domestic designers in the direction of increasing range The ultimate goal is to create an anti-satellite missile .... "


    Well, what is written here that I contradict myself? Fell asleep in the topic of aviation, still want? Do not try so hard to match your nickname laughing . Cheap Russophobian, I'll feed you with manure on any topic, so it’s better to close your mouth right away ...

    For the first time this radar with modules in the form of “bourbals” appeared in 2014. One of the highlights at the upcoming Zhuhai Airshow will be a new phased array radar designed to detect and track stealth aircraft such as America's F-22 fighter jet, reports Huanqiu, the Chinese-language website of China's nationalistic Global Times tabloid. Published November 11, 2014 (“... designed to track.” Has it tracked until there is no information, but modern modules even on gallium arsenide (not to mention gallium nitride) look completely different. If only something unknown to others, like flying Chinese to the cinema...

    Stubborn Israelis, as always, consider the plane’s EPR in the frontal plane, but to their misfortune the EPR from the lower and upper is more than sufficient, taking into account the separation of our air defense, the “invisible” for one F-22 complex (35) is clearly visible to the frontal complexes. To this it is worth adding that the ranges of our radars for various purposes are from meter to millimeter. united by a single air defense system.
