To say that the United States is the absolute first echelon of the pioneer of the fighter plane's airborne phased array radar, especially the active phased array is absolutely ahead, and then the Soviet Union was relatively slippery before that, but the Soviet Union later embarked on the evil path of passive phased array, and it is gone forever. Pen, fun, pavilion www. biquge。 info

So if you really want to say that in addition to the US imperialism in the 90s, the airborne active phased array radar was relatively mature, and it was only Israel, after all, the Ferkang early warning aircraft project played a very big role in stimulating the technology of Israel's airborne active phased array radar.

On the whole, it is definitely a pioneer in technology, if it can be introduced from Israel to manufacture the relevant technology of active phased array T/R components, Changhong said that the relevant problems will be solved within three years, which seems to be in the past.

As for why it is already a technology that has been introduced to Israel, and how it will take 3 years to get it done, this is the problem of the radar band, as the radar wave of the airborne active phased array radar, the radar wave is also transmitted and received by the T/R component, so the T/R component must also be divided into different bands.

I'm very embarrassed to ask: Israel's T/R component on the Fercom system is the L-band, and the radar of this L-band generally does not use the fighter's airborne fire control radar, as for why it is not easy to explain, this needs to talk about the classification of the radar band and their respective advantages and disadvantages, etc., it is difficult to finish for three days and three nights, and you can search by ferry.

That is to say, the introduction of Changhong may only be Israel's T/R component manufacturing technology, and the follow-up needs to prescribe the right medicine to change the radar band to the X-band used by fighter radar, so that it can be used to match the airborne fire control radar to the greatest extent.

However, as long as the T/R component manufacturing technology can be introduced into the L-band, this will definitely be a great tonic for the development of the T/R component of the subsequent fighter airborne X-band radar.

If you want to cooperate with Israel in the last country, it is mainly too blatant, and it is directly necessary to say that the procurement or further is simply to fly the airborne platform to Israel for the transformation of early warning aircraft, and you are so fanfare to pretend to be forced, it would be strange if the Yankees did not interrupt you.

It's good like now, when Changhong and Israel cooperated in airborne radar, Yang Hui reminded to keep a low profile, secretly introduce the manufacturing technology of some T/R components, and not directly introduce the actual product, which is generally very likely to succeed.

And this time Hongdu was able to pass the bidding of Changhong Company, which shows that Changhong has obtained the corresponding various supporting manufacturing technologies, which is possible for them to win the project development and supply contract, Hongdu is now fully implementing the qualification evaluation of AVIC Southwest project suppliers, which has very strict requirements for foreign technology.

Thinking about it so much, he still responded: "Changhong Company has a very good set, since you lost, then admit it, it just so happens that you have no experience in developing small-caliber airborne radars before, and some are only the AWG-14 radar technology that was exchanged from the 9 Institute." And the caliber of the AWG-9 radar also coincides with the caliber of the Su-27 combat radar, I said before that I asked you to modernize the AWG-9 in depth, what is the current situation, is there an eyebrow? Or are you confident in this bid? ”

After a little clear about the situation of the Su-27 domestic radar equipment that came to bid for this time, I learned that the airborne radar of the light four also had a very big breakthrough, which suddenly felt that everything was so beautiful, and the future distance to the successful development of the heavy four has another guarantee.

As for the radar brought by the photoelectric detection system company to participate in the bidding at this time, this is even more comforting, after all, AVIC Southwest is determined to get the radar system of the Su-27 fighter jet in this localization, and now there is absolutely no other unit in China that can come up with a better and more mature radar.

"Mr. Yang can rest assured, the reason why we lost in the light four project last time is not because the radar we provide is worse in performance than the active phased array radar provided by Changhong, this is mainly because Hongdu considers that the light four will be sold abroad in the future. I think that the use of active phased array radar in the fourth generation aircraft will sound more beautiful, so we gave up our machine-sweeping radar, but our technology is absolutely excellent, speaking of Changhong, 14 two units are not necessarily stronger than us, and this time our advantages are more obvious. ”

This remark reveals a new situation, it seems that this Hongdu is still really refined, and we all know that the subsystem is selected according to the sales positioning of the product, you must know that this active phased array radar is a technology that just sounds like it is blowing up the sky, especially after the US imperialist used this thing for the first time on the F-22, the demonstration and advertising effect will definitely not be bad.

Hongdu can be so rogue, then Yang Hui is relieved, although the performance gap between the active phased array radar in the nineties and the last generation of top mechanical scanning radar is not large, but when it is exported, the phased array radar is definitely a tall thing, and with the body of the fourth generation of stealth combat, it must be a sharp weapon for pickling girls.

"Yes, this time it will perform well and compete, China has never developed a large airborne fire control radar of the same caliber before, everyone is on the same level, and you have been tossing on the basis of AWG-9 for many years, I believe this will be a good radar with amazing performance."

The age of the AWG-9 radar is indeed relatively old, and due to the technical limitations at that time, the radar is only based on analog signals, so it will take a lot of surgery to improve it, but this is definitely not to say that it can't be done, at least the Yankees themselves have done this, and they have improved a more modern AN/APG-71 digital fire control radar on the basis of AWG-9.

According to the person in charge of the bidding from the company just now, the radar that is now taken out is the same as the AWG-9 radar for in-depth improvement, and even the route taken is the same as the APG-71, which is to change the radar from analog to digital, and after optimizing some redundant design, the new radar is at least not inferior to the APG-71 radar in air combat.

As for the multi-purpose combat capability, the domestic air force at this time did not have relevant requirements for the domestic Su-27, after all, they all had a more useful J-18, and they were too lazy to bother with the Su-27, so the radar design principle this time is that sentence.

"We focus on the radar's air-to-air combat capabilities, and even in accordance with the AWG-9 design that can guide the long-range Immortal Bird air-to-air missile, and accordingly take into account the guidance of the Russian R-33 long-range air-to-air missile, as long as the relevant interface data of this missile can be obtained, the body of the Su-27 aircraft can launch this missile, and our radar will be able to meet."

That's right, this time it was directly for the localized Su-27 to consider the R-33 long-range air-to-air bomb, which is a very good idea, and then the Air Force will not have to fight the MiG-31 interceptor that can only be introduced in small quantities.

In the later stage of the plan, the Navy will have two main fighters: MiG-31 and J-18, and the Air Force will have three: No. 10, Su-27, and J-18.

The above is almost completely able to meet the professional needs of almost all fighters, and it can be regarded as having a complete professional fighter system architecture, and then all kinds of strong five, J-6, J-7, J-8, side plate lightning and the like, once the life is up, it is said that it is reloaded.
