If you want to develop advanced airborne radar, you must overcome the difficulties of pulse Doppler radar, one of the key subsystems, is its antenna, the efficiency of the flat slit antenna is very high, the radiation energy is the strongest, is the most suitable airborne radar antenna, but the processing requirements of this antenna are very high.

Now, even France has not done it, and the Soviet Union's powerful military industrial capabilities can't handle it, only the United States has put it into practical use ten years ago and played flat-panel radar to the fullest.

As for now, Qin Feng has seen this kind of radar antenna processed by his own side for the first time, looking at this antenna, Qin Feng is extremely surprised and admired, have we finally done a good job?

"Yes, this is our first finished product, we have failed dozens of times, this is the first successful assembly." Teacher Zhang said: "Now, we are testing this finished product, and after the test is successful, we can send it back to the 14th institute." ”

"Does that mean that our own radar is about to come out?" Qin Feng asked excitedly.

The antennas are all there, but are they still far away?

Mr. Zhang shook his head: "No, it's still far away, the follow-up circuit system is being developed in 14 institutes, but it is very difficult, and the progress is slow." ”

The manufacture of radar antennas, the examination is the processing capacity, if the processing accuracy is not enough, you can think of other ways, when we were in the manual control of the machine tool, but also processed the parts of the hydrogen bomb. But the circuit is different, people have an integrated circuit plugged inside, you don't know the model of the integrated circuit, then you can't figure out its technology, the doorway is big.

Even if we get a sample of the AWG-9 radar, if we don't have specific information about this radar, we still can't figure out the model of an integrated circuit, I don't know what it's used for, and we can't analyze the structure of the circuit.

Qin Feng knows that the technical difficulty of this radar is very difficult, and now the team here is just engaged in the antenna, and this antenna is still made after many failures, and the next time the same radar antenna is made, it may take many failures to do it, and the yield is too low, which is also a big problem restricting its mass production.

Wait a minute!

Qin Feng suddenly thought of something.

Since it can't be done at home, then you can learn from abroad, the West is tightly covering the fire control radar, but there are still countries willing to export the most advanced technology, this is Israel, when Israel's Strange Snake-3 missile just came out, the performance is more advanced than the American AIM-9L, is it still exported to China? In China, it is now a way to assemble parts, and it will gradually transition to self-manufacturing.

In terms of missiles, it is possible, and in terms of radar, maybe there is also the possibility of cooperation!

"We're going to go out recently, Mr. Zhang, you can ask your superiors for instructions, and our comrades in radar development can also go out together, maybe there will be gains!" Qin Feng suggested to Teacher Zhang.

After all, going to Israel is still a secret, and Qin Feng doesn't know if Mr. Zhang has the right to know, so he is just a reminder here, and finding a way from abroad is also a way to solve the problem.

Teacher Zhang nodded: "Yes, this is also what we are currently considering, if there is a chance, I really want to go out for a walk and see how people solve it." ”

After speaking, Teacher Zhang glanced at Qin Xue again and said, "Xiaoxue, do you want to go out and have a look?" ”

I? Qin Xue was overjoyed, of course it would be great to be able to go abroad to see it, but what about it, can she do it herself? There are so many senior brothers in this room, who doesn't want to go out and have a look?

"Teacher, I'm still young, leave the opportunity to the senior brothers." Qin Xue said.

There are many opportunities, leave it to the senior brothers, Qin Xue's statement made Teacher Zhang very satisfied: "Qin Xue, although you are very young, but you have a very high understanding, you can understand these things at a glance, so, I am very optimistic about you, this time I went out to see, it will also be helpful for your future growth, and the teacher has high expectations for you." ”

Qin Xue was even more flattered, the teacher was really good to herself!

"Comrade Qin Feng, come to my office." Teacher Zhang stood up and motioned for Qin Feng to follow him, Qin Feng knew that she must be talking about something secret.

I came to Mr. Zhang's office, which was very simple, with a faded desk, a bookcase behind it, which was full of various books, and a sofa underneath, and the sponge inside was exposed.

"The conditions are very basic, you can sit down." Teacher Zhang said: "The country you just talked about is Israel, do you know what is the level of their airborne radar? ”

Teacher Zhang said it just now, just to divert everyone's attention, and now, Teacher Zhang asked Qin Feng, which means that she already knows that the country Qin Feng said is Israel.

Airborne radar in this country, what is the level?

Qin Feng remembered that the last time he went to Israel on a business trip, he was talking with General Lin about the import of the Monster Snake-3 missile, but they also came into contact with some, such as the Cub fighter produced by the Israelis themselves!

"Israel's development in the military industry is very fast, the last time I went was three years ago, at that time, their superior fighter aircraft, has already adopted advanced pulse Doppler radar, the specific model, they did not say, according to public information, it should be the EL / M-2021B fire control radar."

At that time, Qin Feng saw that the radar antenna was flat-shaped, and this radar used the most advanced integrated avionics system, which could share and exchange data with the airborne avionics system network through the 1553B data bus, which was quite an advanced function, and its No. 10 project must also achieve such performance.

Especially now, Israel is still developing the latest Lion fighter, and when they are researching this fighter, they will certainly equip this fighter with the most advanced radar system, and it will definitely be a further modification of this radar, and perhaps, it will be able to reach the same first-class level as the United States.

If you can communicate with Israeli radar experts this time, you will definitely gain a lot!

After listening to Qin Feng's introduction, Mr. Zhang stood in front of the window, looked at the willow tree that was spitting out buds outside the window, and said, "It seems that we should really go out and walk around, perhaps, this time there will really be a harvest." Even if it is worth paying Israel some consulting fees and obtaining some technical information. ”

There is no free lunch in the world, even if it is a simulator that sends Qin Feng out to fly to Israel, it will cost money.
