Super Weapon Swap System

In fact, the radome of the E-2 early warning aircraft is not filled with a flat slot antenna. The radome of the E-3 is filled with a Yagi antenna. Yes, it looks like the oldest TV antenna. Moreover, the band it uses is also UHF, that is, the radio frequency band of the TV. In this way, there will be interference naturally, so people can jump frequency and jump once every turn, Jump to the band with the least interference.

Of course, not everyone can play this way. Its antenna is simple, and its data processing system is quite advanced. Otherwise, how can we process a large amount of data?

Xiong Guo's antenna processing ability and radar processing ability are not good. It's really difficult for them to plug it into a small plane. Now, hearing the other party's words, Qin Guan immediately pretended to be surprised: "do you need our help? Hasn't your an-71 early warning aircraft come out?"

Yes, compared with the jacques-44 early warning aircraft, the progress of the an-71 early warning aircraft is very fast, because the body it uses is ready-made. It can be improved on the body of the an-72 transport aircraft developed by Antonov Design Bureau. How simple are they? Even the radar antenna is directly and neatly mounted on the vertical tail. Throughout the world, there is only one such early warning aircraft radar antenna.

It was precisely because the airframe was ready-made that their planes were built very quickly. They had been built in 1985. It is said that by 1987, that is, this year, they had begun mass test flights.

As for the effect, Qin Guan certainly knows, because he has exchanged one, which is only usable. It is absolutely impossible to say how strong the performance is. In his own base, he used that kind of aircraft for test flight in the early stage. In the later stage, after his maritime police 200 came out, he completely shelved that kind of aircraft.

Now, hearing Qin Guan's words, shuqikov has a bitter smile on his face. This kind of aircraft is one competing with their jacques-44. Although the airframe is very smooth, the radar and the effect are simply terrible. However, people are jet and can take off and land on the jump flight deck. In addition, people's progress is ahead of schedule, so it is really possible for them to succeed in the competition.

It was also for this reason that he wanted to seek Qin Guan's help.

Now Qin Guan has raised this question. What should he say?

"We don't know the situation of the an-71 early warning aircraft. However, according to the information obtained from the radar department, the performance of this radar is very poor. If you want to improve it, you must use a new antenna. Otherwise, it can only work at sea and can't even filter clutter over land."

On the radar of a fighter, if you want to eliminate the ground echo, you need to use the principle of pulse Doppler and carry out high-speed Fourier transform in the computer. For the early warning aircraft, if you do the same, you will face many problems, because the radar sky line of the early warning aircraft is larger and the echo is stronger. If the later processing capacity is not enough, it will be useless, Early warning aircraft mainly used the method of delay lines. Thousands of delay lines of different lengths were densely welded on the radar antenna to eliminate them. This method can not be realized in the radar radome of the compact shipborne early warning aircraft, so it can only be filtered by the airborne computer.

Even the early E-2 early warning aircraft did not have the ability to filter the ground clutter. It was only able to filter the clutter on the sea surface. It was gradually developed in the later stage. There is a gap of at least ten years between Xiong Guo and the Western electronic technology, so they can't solve this problem at all.

Hearing shuqikov's words, Qin Guan frowned: "Well, if that's the case, it's not enough if we only process the radar antenna. The processing system needed in the later stage is also very huge. Even relying on our electronic ability, we have just completed the integration and stuffed it into the body of this kind of aircraft. Therefore, only changing the radar antenna, I don't think it will do much."

"If the post-processing system is added, we cannot export directly due to some restrictions. If you want to refit, you can only send the body to us and refit it in our country. This is also a common scheme for us to refit early warning aircraft in other countries."

For example, Shengjie state has ordered a batch of early warning aircraft from Han state. Han state directly uses the C-130 airframe of Shengjie state. If they carry out transformation on it, they must have flown the aircraft.

Now, when Qin Guan comes to the state of Xiong, he is definitely not here to promote friendship and learn from Lei Feng. What Qin Guan has to do is to have a good relationship and wait to pick fruit in the future.

This kind of early warning aircraft is of a strategic nature. Qin Guan will not export the equipment. If the other party wants to improve, it can only improve it in the domestic of the Han state. In this way, the other party has to take the body. Then, it can be dragged to the disintegration of the Xiong state. At that time, can the aircraft go back?

It's no use going back. The Empire has disappeared, and the other party has only one aircraft carrier to take off. This kind of early warning aircraft can't fly. It's useless. Just stay and test it for the Han state.

Maybe they can also sell it to a third country, such as chicken country. Their aircraft carrier carrier borne early warning aircraft is purchased from Eagle country. It's cheaper and sold to chicken country? Those arrogant chicken people don't know what kind of psychology they will be.

It is difficult for shuchkov to accept the conditions put forward by Qin Guan. Yes, they need advanced radar equipment, but let's say that this kind of aircraft is sent to the state of Han to install radar equipment. Who developed it or is it the product of yaklev design bureau?

However, it seems really inappropriate to use only radar antenna, because our own side is indeed backward in those post-processing circuits.

Shuchkov can't be the master.

"Now, your airframe hasn't been made yet?" Qin Guan continued: "you can make the airframe first and leave enough space and power supply. We can also slow down for radar. Maybe our communication will be further in the future?"

Of course, Qin Guan knew what he was embarrassed about. In this case, he must hesitate. How could he give this aircraft to the state of Han for refitting? However, now he buried the foreshadowing and laid the foundation for the future. Who would have thought that Jacques 141 was a power pack together with the state of Han?
