Chapter 274

If it weren't for Chief Engineer Su personally saying that the 607 Institute had accumulated a certain amount of experience in phased array radar and had also finalized the model, Wang Zhengguo would never have thought of proposing the idea of developing phased array radar.

Don't think that the phased array radar after 2,000 years is "rotten on the street", just think that the technical content of this thing is not high, but in fact it is the opposite.

A country that can really develop phased array radar must have a rich accumulation of electronic technology, and if it cannot pass the test of semiconductor microelectronic technology, it is impossible to do much in this regard, and Russia is considered a typical example.

Now, since 607 has its own technical accumulation in the development of airborne phased array radar, even if it is the most critical kick in the technical threshold, it should have been studied in detail on the relevant technologies, and the only thing that is needed is to look at the domestic semiconductor electronics manufacturing technology.

And when it comes to the basic semiconductor production process, now Wang Zhengguo is smiling, this is clearly to send food to Kaiyang Semiconductor!

Wang Zhengguo had the idea of agitating the 607 to be a phased array radar in a short period of time, but Chief Engineer Su was very clear about the difficulty of developing the airborne multifunctional phased array radar.

If we really have the ability to develop it, then of course we can beat the gaps in the flats that participated in the bidding this time, but the problem is that we cannot do this kind of thing with our domestic technical foundation. ”

The idea is very good, but the reality is quite cruel, beckoning to Wang Zhengguo, who is sitting across the desk, and motioning to follow him out of the door.

"In this case, come with me first, and after taking you to see the phased array radar next to the electric sweep developed by the institute, maybe your mind will change by yourself. ”

The institute generally has a special place to display its scientific research results, which is the same as the process of visiting the lithography machine of the Shudu Institute of Optics and Mechanics before, and there is not too much trouble to visit the phased array radar of the 607 Institute this time.

Open the dusty door, and walk in, in a prominent position in the center of the room.

The place that catches the eye is definitely a behemoth, first of all, this antenna array is long, about four meters long, such a size in the field of airborne radar, it can definitely be regarded as a big guy, you don't have to think about it, this should be installed on the belly of a large aircraft or on both sides of the fuselage, anyway, the nose space is absolutely not installed.

"This is the phased array radar we developed, the reason why there was a development task of this radar back then, is that at that time, considering that the array of phased array radar can achieve a more flexible antenna installation arrangement, but the reason why it is not equipped in large quantities is mainly because the performance of the TR components used in the radar is not good, and this is not something that we can solve unilaterally in 607. ”

After saying that, he picked up a fist-sized block of equipment next to him and handed it to Wang Zhengguo indifferently.

"This is the T/R component used on the radar, this thing was not designed for airborne at the beginning, it is actually another key project in China supporting the development, we are using the T/R component that has been successfully developed, and it is barely used after a slight improvement. ”

Feeling the heavy weight on his hands, combined in two lifetimes, this is also the first time to see the real phased array T/R component in kind, although there is a difference from the statement that the T/R component is only the size of a coin in the upper plane, but this can also be thought about, after all, it is something made in the seventies of the Republic, and how high the system integration can be expected.

As for the other key project just mentioned, he could roughly guess that the key phased array radar project in China that could be ranked in the 70s was nothing more than the missile early warning radar project specially developed for nuclear war by Unit 7010 of Huangyangshan, and the equipment of the entire regiment was only one radar, and the big guy with a huge radar array of 40mX20m.

The T/R component developed specifically for this radar was slightly modified for use in the airborne side-by-side phased array sea-to-sea search radar, which may sound like a viable solution, but the gap will not be realized until the actual product is tested.

After all, they have specially developed anti-missile early warning radars, and we will not talk about whether the radar band corresponds to the band of the sea search radar, and this is only the most basic place, and other problems are certainly indispensable.

"It's quite heavy, I'm afraid the cost is not low, right?"

Although he can guess the original origin of this thing, but since Chief Engineer Su didn't say it, he definitely won't show his knowledge, who knows that the 7010 radar is still not a top-secret project, Wang Zhengguo thinks about it or a little low-key, and that's when it comes to the T/R component itself.

Hearing someone ask about the cost, Chief Engineer Su smiled.

"Cost? In order to pursue performance, this thing is almost cost-free, and the most basic silver materials are used casually, not to mention the investment in the semiconductor process itself. ”

There are actually different differences between the T/R components of phased array radar, and the prices of different components are also very different in different radar bands, so it is difficult to have reference value in terms of price.

At this time, Wang Zhengguo can roughly guess what is the situation of the phased array radar antenna system next to the 607 electric sweep, which is based on the electronic technology of the Republic in the 70s, and even the most critical T/R components do not match the working needs of this radar.

It can be regarded as a thorough understanding of the fundamental reason why although this radar was successfully finalized, but in the end it was not equipped with a large number of equipment on the Water Bomb 5, which is of course related to the fact that the Water Bomb 5 project itself was not mass-produced, but it is also closely related to the lack of performance of this radar.

"I understand, what Chief Engineer Su means is that if you want to develop a phased array radar, you must re-develop T/R components with better performance, and if you want to say that the development of the east and the west, it is not so easy in itself, and the institute actually doesn't have much experience in this area?"

Someone said straightforwardly, and directly laid out the problems that the 607 Institute is currently encountering on the phased array radar, which made Chief Engineer Su a little embarrassed.

"That's right, that's what it means, at the moment we see that this T/R component is definitely not usable. There are not many people in the institute who can engage in this kind of research, it itself is designed by 14 institutes, and only six of our designers have experience in improving the design of this thing, but if we want to develop a new T/R component, we have never done it, and if we start from scratch, we will definitely not be able to wait. ”

There is definitely no way to hide this kind of thing, and a discerning person can probably know it as long as he sums it up a little.

"Moreover, our domestic semiconductor technology is not advanced, and there is still a certain distance to reach the international level, not to mention that the development of fighter aircraft-borne phased array radar is mainly because foreign countries have made breakthroughs in the matrix material of T/R components and developed gallium arsenide single crystal. And we don't have any of them. ”

The words are very clear, and it is clear that the time to launch the phased array radar at this time is not mature enough, maybe spend money, plus use time to grind, and finally be able to get reliable T/R components, but the time will definitely have to wait until the 90s.

Sure enough, there is still a big gap between the ideal and the reality, and it cannot even be made up for in a short time, which makes Wang Zhengguo feel a sense of loss.
