China has developed technology that significantly increases the ability to detect American F-22 stealth aircraft

Chinese scientists have developed technology for detecting American stealth aircraft that can amplify the extremely weak signals of not only the F-60 and F-22, but also the B-35, which has not yet entered service with the US Army, by 21 thousand times.

According to the South China Morning Post, last year China developed technology for detecting and locating stealth fighters in the infrared spectrum, which can detect F-22 aircraft at a distance of up to 300 kilometers. Thus, the technological capabilities of the US Air Force in the Western Pacific were significantly reduced.

Thanks to new Chinese technologies, it is possible to detect the F-22, considered one of the best stealth fighters in the world, whose frontal radar cross-section does not exceed one square centimeter. Leading American fighters are detected as soon as they enter visual range of infrared-guided missiles.

Thus, thanks to timely detection, American fighters are effectively deprived of the stealth ability to launch missiles or deploy glide bombs as they approach the theater of operations.

As stated in the relevant documentation, the new detection method makes it possible to cover an area of ​​about 63 thousand square kilometers with an error not exceeding 20 meters. No matter how the F-22 maneuvers, it will not be able to avoid being picked up by air defense radars.

A very interesting and serious development, if not a fake...
Now the Indians will start to burn in the place for which they are most worried.....

[LuckyBlog]

and what's so serious about it? Have the Chinese invented OLS again?
I was especially pleased that the detection occurs at the range of capture of the IR seeker of missiles. If anything, the IR seeker is for short-range missiles (although there is a medium-range R-27T, but it is fired from an aircraft and only at the terminal section is the seeker used). that is, their IR seeker captures 300 km? I remembered how in the 90s they sold Chinese tape recorders with a player mechanism and there, like, the power of the speakers was 1000 watts, 2000 watts, 10000 watts, the same song. only now 300 km pmpo

significantly increasing the ability to detect American F-22 stealth aircraft

I realized that the detection range of "invisible" devices would increase. This may be possible with a significant improvement in the sensitivity of RET radio receivers and transmitter signal power.

[LuckyBlog]

what kind of transmitter does the passive infrared system have? minus is not mine.

[spirit]

Thus, the technological capabilities of the US Air Force in the Western Pacific were significantly reduced.

Thus, all this is Chinese bullshit until they actually check it. We also had statements that everything that flies will fall from electronic warfare almost to Kiev. As a result, after more than 2 years of war, there are swarms of drones in the air and strategic unmanned aircraft are quietly flying over the Black Sea scouts. All this training know-how is worthless.

in reality it may not be a penny, but the loss of image could significantly undermine the American “invisible” program. Especially if the Chinese slip good misinformation to the CIA.

[KCA]

Compare the cost of manufacturing even an average UAV and an electronic warfare complex, the speed of production, the quantity required to cover the front line and border, the quantity at facilities in Russia, it is clear to everyone that drones launched from our territory by saboteurs also work, there are not so many electronic warfare complexes in the whole world, with air defense/missile defense systems it’s the same story

[topol717]

and strategic unmanned reconnaissance aircraft calmly fly over the Black Sea

They fly in international waters, and according to international standards, no one can prohibit them from doing so. Electronic warfare can disable communication with the operator, sometimes, but not always, suppress GPS. If the UAV flies in automatic mode, then this electronic warfare is of no use to it.

[LuckyBlog]

but electronic warfare can greatly hinder the collection of intelligence data

[nedgen]

Quote: LuckyBlog

but electronic warfare can greatly hinder the collection of intelligence data

But this is far from a fact. Typically, strategic intelligence officers, in addition to transmitting data in real time, also record information. If, with the help of REB, the communication signal is jammed, then in fact it only increases the time for data delivery before the UAV leaves the suppression zone, and if the control channel is suppressed, then Pin...dos after the landing of one UAV a couple of years ago installed an automatic return system to the airfield. Even if the GPS signal is suppressed, there is still an inertial control system on board and the UAV makes a turn home and control is restored over time. Unfortunately.

Globalhawks have a radar, and the optics can be blinded with a laser, weak enough to damage the optics but enough to illuminate everything.

[Last centurion]

I don't think it's bullshit. They tested quantum communication with satellites, where every photon counts

[Amateur]

technology was developed to detect and locate stealth fighters in infrared spectrum,
No matter how the F-22 maneuvers, it will not be able to avoid capture radars air defense systems.

Some kind of set of words. If in the infrared, then what does radar have to do with it, and if in the radio range, then from which side is the infrared radiation?

[Argon]

Infrared radar irradiators piezo ceramics...

[KCA]

It’s quite simple ROFAR, if ours are being developed (or made) China is clearly aware and is also closely working on them, just for fun I looked, Zen writes that from 2024 the SU-57 will be equipped with ROFAR as standard, although Zen doesn’t have much faith

[LuckyBlog]

ROFAR and IR are not connected in any way. ROFAR is essentially an optical radar where instead of electrons there are photons, but still on the same principle - radiation - reflection-reception of a reflected particle.

[KCA]

I know, but in the article itself where is it written about IR radiation sensors? Everything follows the same principle, but in size and weight ROFAR is 2-3 times lighter and smaller than AFAR, and in sensitivity it is at least 10 times greater, and it gives out not a point, but a target outline

[LuckyBlog]

The article indicates the IR range, this is not ROFAR, and the thermal imaging image also shows the outline of the target. Look on the Internet for a view of what the GOS UR BB Python receives from Israel. The same theme applies to Southwinder X mattresses.

[KCA]

Hospita, if a penny-eater for an article translates Google or Yandex without indicating the source, do you completely trust him? Instead of smart people, there are a lot of high-guzzlers. IR guidance 0.5-3 km, Yozhik knows

[LuckyBlog]

The ols detects the target at 90 km, the f-35 ols detects the BR faker at 800 km

[Andy_nsk]

I read about ROFAR, they really work in the optical range, they include a matrix of semiconductor lasers and a matrix of photodetectors, control of the beam direction - due to modulation and phase mismatch of signals in the matrix elements. Smaller antenna sizes are obtained through the use of optical fiber (the active elements are located outside the antenna). The connection with IR is caught in the fact that the carrier wavelength is 1,6 microns. Judging by the range of manufactured components (lasers and photodetectors), the damned Zakordons are in the lead; here in Baumanka they are also trying to do something, but I know how developments are carried out at universities - so I am very pessimistic. Well, from the physics of the work it is obvious that STEALTH technologies become useless when using ROFAR. I strongly doubt about 300 km. Humanities journalists trying to write articles on complex technical topics should be deprived of the right to write such articles for life!

That is, it does not work in bad weather, but at night it illuminates the position of the aircraft?

[Andy_nsk]

no, it doesn’t highlight anything (for the eyes, at least), 1,6 microns is the near-IR range, it works as a locator, but not on radio waves... and IR, and visible light, and radio waves are all electromagnetic radiation , just different frequencies (or wavelengths), and it is possible to make a locator at any of these waves, they are just starting to do it at such short waves, there are many technical problems, judging by the graph I found, 1,6 microns passes well through the atmosphere, but it is necessary, Of course, direct visibility beyond a horizontal location is most likely impossible.

ROFAR locators search for enemy aircraft:

locators operate on a reflected signal and the delay time is measured.

Yes

That is, work has been going on on a powerful laser roulette for so many years?

[Andy_nsk]

No, the problem is not only in power, with the help of a tape measure it is impossible to obtain an image of the target, matrices of laser emitters, matrices of photodetectors are used, these matrices are connected to the antenna system by optical fiber and all this is quite difficult to control with the possibility of spatial scanning.

[DenVB]

Quote from Andy_nsk

No, the problem is not only power, it is impossible to get an image of the target using a tape measure

Can. Only the tape measure is called a 3D laser scanner.

[vargo]

I also noticed. Some nonsense from the author of the text.
In fact, if we ignore the secret way to increase the sensitivity of the infrared sensor, the question remains. They say that it is possible to detect the enemy at 300 km. But it doesn't say from what height. But at the end they give the coverage area, and it is already closer to reality. If you place the aircraft at an altitude of 100 meters and the detector on a mast at +/- 15 meters, then we get just a control zone of ~60 km².
It’s just that such a system will see the plane in line of sight. This is of course ideal.
However, there is no talk of any 300 km from the ground (you need to raise the sensor higher). And the question remains about the supersensitivity of the sensor. Is it revolutionary, and will it really help against stealth, remains a question

[LuckyBlog]

there, along the way, the Chinese simply improved the sensitivity of the OLS and began to sing about the Chinese technical revolution. the F-35 OLS detects the torch of a ballistic missile from 800 km, but mattresses don’t come up with fairy tales about detecting stealth

[bya965]

Articles are written by people who can speak well, but often do not understand what they are talking about.

Any radiation from a body in all directions, if there is no resistance to the medium (even if there is not, otherwise the dependence is even stronger) falls along r^4 (r to the fourth power). Those. at a distance of 2 times the signal power will drop by 16 times, and if it is a reflected signal then by (2*r)^4 = 256 times.
Those. We won’t see it with a super-cool device at a distance of 300 km, but we’ll definitely see it at a distance of 100 km.
And the article is a typical advertisement

one of the best stealth fighters in the world, the F-22, whose frontal radar cross-section does not exceed one square centimeter.

And as a side view, top left. Clearly, the less visible the better, but what price should you pay for it?
Let's remove the tail unit from the plane, the speed and range will increase, but what about takeoff/landing, how about maneuver?
The left article, here ordered by Israel, bought the F-35, now we need to show that if the F-22 is cool, then so is the multiplied iron, or is it the penguin?

[Andy_nsk]

Any radiation from a body in all directions, if there is no resistance to the medium (even if there is not, otherwise the dependence is even stronger) falls along r^4 (r to the fourth power).

To the second degree. You are confusing it with active radar, when the target is irradiated by the radar and then receives the reflected signal, i.e. the radio wave first passes from the antenna to the target, and then from the target to the antenna, then the fourth degree is actually obtained.

That's exactly what I meant. I probably wrote it unclearly.

1. IR sensor... in "CRYOGEN" from head to toe = hypersensitivity. The Stingers were the first on this path. Maybe the whales cooked up something similar? If this is so, then there is definitely no “revolution”.
2. On the issue of detecting "invisible" devices. They are not visible...maybe so. But the indignation of the “environment” is like two fingers on the asphalt!
3. The Yankees also really hoped for the “silence” of their submarines. But there were Lechin brothers who taught mathematics well at school. As a result, the algorithm they created for processing the g/a signal (bare mathematics! even with our poor technology) works wonders... absolutely silent boats become visible! Yankees in a..u..e!
I am sure that the whales followed the same path as our Kulibins!
AHA.

Read about the development of radio-photonic locators! Maybe this topic will reconcile you!

[Knell wardenheart]

All such statements by the Chinese should be treated with some skepticism. “Technology developed” can mean a lot of things - for example, that they filed a patent based on a certain principle, but all this is not embodied in the metal and the workability and effectiveness of the solution “in the form” has not been proven.
Also, in my opinion, there is some kind of murky duality in such statements - it is not clear what exactly they have developed - a gadget for radars capable of identifying and tracking targets like the F-22, or IR sensors capable of detecting it at considerable distances.
If we are talking about IR sensors, then I have no idea how it is possible to detect a target in the frontal projection with “tail” radiation, especially with technologies for reducing the exhaust temperature, deepening the nozzle and various tricks that reduce IR even from the most visible areas - at designated distances. Even from the side or below this will be a problem, and at much greater distances. Sensors of similar qualities will be illuminated to death by the sun, heat reflected from water or clouds, and air convection currents - if we are really talking about sensors capable of detecting the IR range of such a weak source at such distances.

If we are talking about radars, then absolute “stealth” did not exist - the problems of detecting and tracking it were solved before - including through the interfacing of several radar installations into a network with processing and exchange of information. In this case, it is possible to determine the characteristic features of the movement of an object with low RCS and unambiguously determine it through this.
However, all this will work in an exclusively active mode and, therefore, countering this means removing radar capacities (or at least disrupting their complex), for which the Americans have the means.
In short, let’s hear what happens next on this topic, for now it looks more like another Chinese duck..

[dzvero]

Perhaps they created something like ROFAR. But the description looks like a Google translation from Chinese to English and then to Russian.

[KCA]

I, of course, understand that ancient HARMs are supplied to/from the United States, with two knocked down or fallen nameplates bearing the production years 91 and 98, but I wouldn’t elevate the new modifications to the rank of superweapons

[Tarusa Petrova]

Now China needs to share this new product with us.

[Thrifty]

What to share? Crazy? Do you at least understand the length of IR radiation, and the mythical 300 kilometers will not change anything if the plane may have a missile with a flight range of over these very 300 kilometers!

[Sergey3]

Today at VO there is a parade of articles with clickbait headlines? That’s exactly what I imagined: a B-21 is flying, the Chinese turn up the radio signal amplification by 60 thousand times, and then I turn on my smartphone and climb into the VO, and the poor Chinese has a white screen from interference. In general, to the trash can of such scribblers...

[rocket757]

If we remember... a qualitative leap in the issue of the effectiveness of radio coating was given not only by new methods of scanning space, but also by the use of digital technologies in the process of decoding and analyzing the received signal, information, i.e.
They talk a lot about AI, but the creation/use of a high-performance computing complex, specialized algorithms, processing/analysis algorithms, can add efficiency in controlling the air, and indeed any other space/environment!
I’m sure this topic is developing at full speed, but they talk about it a lot/publicly, it doesn’t matter anymore.
“invisibility” is a myth in general, at this stage of technology development, and stealth is against the effectiveness of new means/methods of detection, who will win??? This is an interesting question.

[Anchonsha]

No, guys, there is no need to blaspheme our electronic warfare. Now in the Northern Military District we don’t need to reveal all our cards to NATO about what our electronic warfare systems are capable of. They always listen to us in all respects. And flying US reconnaissance drones near the Black Sea just need to be shot down with advance warning of interference in the Northern Military District on the side of Zeli-Jewish Bandera. And not all drones can be neutralized using electronic warfare.

[rocket757]

Obvious... not to everyone, but everyone decides for themselves.
The confrontation with the united West remains in the stage, almost hot, but not, for only one reason... we have vigorous arguments that can wake up on hot heads and bring them to a state of ashes!!!
But we need an unconditional, decisive victory over the new Nazis and with the least losses!!!
Then conversations/negotiations with foreigners will acquire a new meaning, basis, and so on, so on...
There is no need to save, it can backfire!
