In the Irasu War and the Yugoslav War, the United States "mouthed stealth fighters and? The stunning appearance of the stealth strategic bomber and the precision strike capability displayed by it have made all countries in the world seem to talk about "stealth" almost overnight, and the research on the anti-stealth capability of radar has also been raised to an unprecedented level, which has become the focus of many countries' current military work.

Overnight, it seemed that the whole world was afraid of stealth planes, and everyone seemed to have a sense of not being able to sleep well without solving the problem of stealth of planes.

After re-analyzing the world's radar technology, we found that among the existing technologies, passive radar, long-wave radar, meter-wave radar, millimeter-wave radar, and phased array radar, the high-power active phased array fire control radar is the most likely to be used on combat aircraft for reconnaissance and air combat against stealth aircraft.

Although the detection ability of the existing airborne phased array fire control radar for stealth aircraft is far less strong than that of non-stealth aircraft, it is already very good compared to traditional radar, and if you integrate ground-based radar resources to detect stealth aircraft, with the guidance of ground-based radar, the combat capability of stealth aircraft is actually not bad.

This last sentence of Feklisov is undoubtedly a great stimulus to the development of domestic military radars capable of countering stealth aircraft.

"So exaggerated?" Wang Qiang and his two guards widened their eyes in disbelief, if this is really the case, this radar can be called a concubine level, not to mention that in China, even the Americans do not have such a good performance of the airborne fire control radar, right?

At present, the United States does not have such a good radar for the time being, and although there are many airborne radars that exceed this radar in various performance indicators, in terms of technological advancement, there is indeed none.

"And that's not all." Seeing the ghost-like expression on the face of his customer, Feklisov looked proud, fighter fire control radar is not cheap, can sell more radar, for these people, it is undoubtedly an important issue related to the degree of apology of their wallet, "At present, we are improving this radar, and the improved radar performance will be more superior, after the improvement, the maximum search distance of the radar will reach more than one kilometer, and the guidance distance of long-range air-to-air missiles will reach one kilometer." At the same time, the detection capability of stealth aircraft will be correspondingly enhanced

If you look at the data alone, the performance of this radar is quite close to the Qujian passive electronically scanning phased array fire control radar that the Soviet government equipped for the MiG air high-speed interceptor during the former Soviet Union, as well as the one being developed by the Americans? 2. The concave knife active electronic scanning array radar used on the fighter jet, after all, the scanning distance of the radar used by Yichou is only one kilometer.

Wang Qiang touched his shaved chin vigorously, and grinned vigorously: Although I don't know if the ability of this radar to detect stealth aircraft is true that this Russian said, after all, no stealth plane has experimented on itself, but as long as everything else they say can be realized. For China's security army, it is also extremely tempting.

The only pity is that there are no long-range air-to-air missiles in the country, and even medium-range air-to-air missiles have quite average performance. Thinking of this, Wang Qiang was a little depressed in his heart: although it is very depressing not to see, what is even more depressing is that it can be seen but cannot be played.

"Although our radar is a little worse than the electronically scanning passive phased array fire control radar used on the MiG in the former Soviet Union in various performance indicators, but because our radar is active, from a technical point of view, it is not a little bit stronger than their radar, but a whole generation higher! Although Russia is now engaged in the research of airborne active phased array fire control radar, it will take at least a dozen years for them to succeed". When he said this, this guy was proud that he was able to successfully develop an active phased array fire control radar, which was indeed a very proud thing for them radar engineers in the former Soviet Union.

"What else is there? Wang Qiang, who came with an important mission, was quite ashamed to ask questions at this moment.

This sentence asked the itch in Feklisov's heart, and the guy immediately began to drip: "The electromagnetic radiation of our phased array radar is quite flexible and controllable, and compared with the current Airborne Radar of the Doppler system, this radar can distribute radiation energy in space

… Concentrate energy where there is a chance that a target will appear. It can flexibly control the tracking of the target and improve the stability of the tracking. High detection and tracking capabilities;

"Beams of different shapes can be formed, such as needle-shaped beams, sector beams, wide beams, etc., as well as zeros can be formed in the direction where interference exists to suppress active interference, and when necessary, can even be used as antennas for electronic warfare and as weapons of electronic warfare countermeasures; At the same time, compared with conventional antennas, this radar has the characteristics of low side lobes, the peak value of the side lobe can be reduced to more than Ding Zhaopin, improving the detection performance of the side lobe clutter area, and improving the anti-interference ability of the side lobe, and now the peak value of the side lobe of the radar used on the MiG first lead is only barely reduced compared with the traditional Doppler radar antenna, even if it is not much different from the Zhaodao phased array radar used on the Yihu fighter used by the American fighter and the tire lead phased array radar used by the Yiwu fighter. ”

"But don't forget, these two radars of the Americans have not been officially put into use yet, our radar can be officially put into use after testing, and what a big advantage it can form in military terms if this equipment can be put into use in advance, I think General Wang You should know best Feklisov Shixuan does not forget to help his boss and his own products say good things, after all, the more products in the company are sold, the more benefits they can get.

Wang Qiang agreed with Feklisov's remarks.

Although he is only a senior commander of the army, as a general and an excellent military commander, his eyes will definitely not only focus on his own one-third of an acre, but also study the topic of how to achieve the greatest results in the context of the current era while doing his own work. ,

Obviously, then, in this era when a large-scale all-out war is no longer possible, it has become a top priority for the Chinese military to conduct a technology-intensive coordinated operation by multiple arms of the armed forces to cope with a local high-tech war, and how to seize the initiative on the battlefield ahead of the enemy has become the main content of their study. Radar, which has been the eyes of the army since its birth, is naturally one of the equipment that these soldiers attach the most importance to.

However, because the level of military science and technology in China is relatively low, the domestic airborne radar technology is now somewhat embarrassing, and the problem of "myopia" has always existed in the domestic air force, and how to solve the problem of "myopia" in the air force has become a headache for the top military leaders in recent times.

"The high-power traveling wave transmitter and mechanical scanning parts that are prone to failure have been eliminated, and the antenna is composed of multiple array elements, in which the gills fail, the radar can still work effectively, so the reliability of the radar is quite high. Compared with the current Doppler radar, the average maintenance interval of our company's radar has been greatly extended, with the current general force hours or so, increased to about force hours, the next step, our goal is to make the average maintenance time of this radar reach force hours;

Although he is not from the Air Force, Wang Qiang still has deep feelings about Feklisov's words, and an indisputable fact is that the radar equipped with the fighters of the domestic Air Force not only has the problem of "myopia", but also the congenital "weak system" and the short average maintenance interval is a problem known to everyone in the Air Force, and this problem is even worse than "short-sightedness." What's more!

Suppose that if you are in an air battle and suddenly have a problem with your radar, and all the weapons on the plane are not able to be fired except for the cannon, maybe because of this, a good position that you have managed to grab before is wasted, not only can you not shoot down the enemy, but even your own safety will be problematic, which is really terrible.

Although we have thought of a lot of solutions, but for this problem, we have not been a good solution, if the Alice Group's radar can really reach the average maintenance interval they said to reach the time of the Kab, then for the Air Force, it is simply too good news to be good, as long as this is really satisfied, even if the other performance shrinks to a certain extent, it is not unacceptable.

"Removing the antenna base and mechanical rotation device of the mechanical radar can reduce the radar reflection area on the front of the aircraft, and at the same time, the scanning beam of the phased array radar antenna can achieve instantaneous agility compared with the Doppler radar with a fixed beam, and the radiation energy can be flexibly controlled in time and space, so the probability of being detected by the opponent's radar alarm is reduced, and the stealth performance of the radar is good, which is complementary to some of the things mentioned before." （
