In addition to Italy, there is also the French company Thomson-CSF, who provided the RC-2000 made of the Mirage 5-400 RDY radar, which after years of development, finally became a flat slot radar with outstanding performance, and at the same time, there is the EL/M-2032 of the Israeli Elta, which was originally developed for the Lion fighter, and after the failure of this project, the Israelis sold it all over the world, hoping to sell it.

In fact, even if it is a domestic radar, it can find the bloodline of the latter, but it has long been able to eat all the technology, and then it has been improved, and the blue is better than the blue.

Everyone has confidence in domestic avionics.

"Compared with foreign radars, we have made a lot of our own, and now it is more mature, that is, the products of the 607 Institute, medium range air interception, close air combat combat, ground and sea attacks, auxiliary navigation and other functions are available, high, medium and low repetition rate of a variety of waveforms, and even adaptive pulse compression and adaptive waveform management, in the tracking and scanning function can track 10 from 40 targets, and can control two over-the-horizon missiles to attack two of them, and the radar reflection cross-sectional area of 3 square meters of targets, the detection distance is greater than 75 km, the downward viewing distance is greater than 45 km, and the detection distance for sea surface targets is greater than 135 km. ”

It can be said that from the point of view of performance, it is completely pressed against other competing products, which is also inseparable from the credit of Song Lao, and the design institute must make first-class products if it wants to get orders!

"In addition to these functions, because we do it ourselves, this kind of system is easy to cross-link the friend or foe identifier with the radar, and obtain good electronic countermeasure capabilities. If compared, the comprehensive performance can reach the level of the early F-16 Block 50/52. ”

This is even more advanced than the F-16 fighter that Lao Ba is now equipped with!

"In fact, with the development of avionics technology to the present, if you only compare the radar performance, you think it is advanced, and it is obviously outdated." Qin Xue said that as an engineer in avionics technology, Qin Xue's vision is more long-term.

"What's that?" Even Qin Feng really didn't know this.

"Of course, it is the comprehensive capability of avionics, which is even more advanced, and even at the leading level in the world." Qin Xue introduced.

The original avionics system was a discrete structure, with radar, communications, navigation and other equipment each having its own dedicated and independent antenna, RF front-end, processor and display, etc., using point-to-point connection. The various systems are not connected to each other, so there are thick cables on the plane, and the cockpit equipment is extremely bloated.

Later, there was a joint structure, using data bus technology, connecting all the equipment together through the bus, simplifying the layout, using several data processors to complete the data transmission and exchange display light function, such as navigation weapon delivery, plug-in management, display, control, etc., the avionics of the current fighter is mainly this level.

As for the new generation, it is the integrated avionics structure, its degree of integration is further improved, and the integrated core processor shared by the system is used to complete almost all the signal and data processing, which used to be discrete computing, and now it is a comprehensive calculation, including fire control calculation, navigation calculation and management, cockpit display pattern generation, plug-in management, system task scheduling, system integrity monitoring and other calculations, scheduling and management tasks, so that the performance of avionics can be more effectively improved, and the burden on pilots can be reduced. This kind of avionics, represented by the F-22, even began to use optical fibers in order to adapt to high-speed data transmission.

These are the main three, and of course there are more advanced, highly integrated avionics architectures. In the two major fields of radio frequency and optoelectronics, modular design is widely used to realize the integration of radio frequency functions, for example, friend or foe identifiers, the previous special, now, the use of radar can be implemented, and even with the continued development, radar will disappear, those antennas can be arranged on the skin of the aircraft, completely controlled by software, to achieve radar, communications, electronic warfare functions.

The Thunder Dragon fighter still uses the 1553B data bus, using two sets of systems to guard backup, but in terms of data transmission, it has been greatly advanced, it can be said that it has exceeded the degree of the second generation of avionics, and the third generation of integrated avionics structure concept is very close.

Qin Feng listened to it with an eye-opener, feeling that he was really old and outdated, so many advanced terms, I had never heard much of it before, and now, I finally understood, our electronic technology is progressing very fast, and it is more advanced than that of the F-16.

For pilots, the benefits of advanced avionics, which are well known, liberate pilots to conduct better air combat.

For example, the avionics system has a high degree of integration, and the radar warning receiver can even automatically release platinum strip jamming or infrared decoy bombs at the most appropriate time after discovering the incoming missile.

"Our technology in all aspects is progressing very quickly, but it's a pity that there is one aspect." Qin Feng thought of something and sighed again.

"What a pity?" Yang Gong asked.

"Stealth performance, now the air combat has entered the era of stealth aircraft, but unfortunately in this aspect, we are still blank, we have no stealth technology in China, this is always a defect, in the future, what do we use to fight against the American F-22?"

Just like a few years ago, the J-8 was used to fight the opponent's F-15, and now that it has a third-generation aircraft, it is already a fourth-generation aircraft, especially this stealth, it is simply an uncrackable game.

"There will be bread, there will be everything." Yang Gong said and patted Qin Feng on the shoulder.

How do you know, we don't pay attention to stealth, the future development, Song Lao is watching, the research and development of the next generation of fighters has begun.

It is very meaningful to give the J-10 a successful test flight, in addition to the finalization of the J-10, it is also the beginning of a new fighter!

Of course, this can't be said to Qin Feng now, after all, it's not that time, even in Chengdu, there are very few people who know it.

Song Lao will not retire just now, Song Lao is still catching up with the world's advanced footsteps! What the Americans have, we also have to have, stealth aircraft, what's so difficult? We believe that we are the most creative people!
