Super Weapon Exchange System

In fact, the radome of the E-2 early warning aircraft is not stuffed with a flat slot antenna, the E-3 is, and the E-2 is stuffed with a Yagi antenna. Yes, it looks like the oldest TV antenna. Moreover, the band it travels is also UHF, which is the frequency band of TV radio broadcasting. In this way, there will be interference naturally, so people can hop frequency, jump once in a circle, and jump to the frequency 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 it handle massive amounts of data?

Xiong Guo’s antenna processing capabilities were not good, and his radar processing capabilities were not good. It was really hard for them to squeeze into a small plane. Now, when he heard what the other party said, Qin Guan immediately pretended to be surprised: "This Do you need our help? Your AN-71 early warning aircraft, isn't it already out?"

That’s right, compared to the Yak-44 early warning aircraft, the progress of the An-71 early warning aircraft is very fast, because the airframe it uses is a ready-made aircraft, which is a short take-off and landing An-72 transport aircraft developed by the Antonov Design Bureau itself. The body can be improved, how simple are they? Even the radar antennas were directly and neatly mounted on the vertical tail. Looking at the whole world, the radar antennas of early warning aircraft are placed in this way.

Precisely because the airframe is ready-made, their airplanes were built very quickly. They were already built in 1985. It is said that by 1987, that is, this year, large-scale test flights have begun.

As for the effect, of course Qin Guan knows it, because he has already exchanged one, and it is only usable. It is absolutely impossible to say how strong the performance is. In his own base, use that in the early stage. This kind of aircraft has undergone a test flight, and in the later stage, after our Marine Police 200 came out, they completely put that kind of aircraft on the shelf.

Now, after hearing Qin Guan's words, Shuchikov's face had a wry smile. This kind of aircraft was a rival to their Yak-44. Although the fuselage is very smooth, the radar and the effect are simply horrible. However, because they use jets, they can also take off and land on the leap deck. In addition, their progress is advanced. Therefore, it is really possible to make They succeeded in the competition.

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

Now that Qin Guan raised this question, what should he say?

"We don’t know how the An-71 early warning aircraft is doing. However, according to the news 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 Working at sea, when you reach the sky above land, you can't even filter the clutter."

On fighter radars, if you want to eliminate ground echoes, you need to use the principle of pulse Doppler to perform high-speed Fourier transform in the computer to achieve it. For early warning aircraft, if you follow the same method, you will face many problems. Yes, because the radar antenna of the early warning aircraft is larger and the echo is stronger. If the processing capacity in the later stage is not enough, it is useless. The early early warning aircraft mainly uses the delay line method to weld thousands of radar antennas densely. In the radome of a compact carrier-based early warning aircraft, this method is definitely not possible to eliminate the delay lines of different lengths. It can only be filtered by the on-board computer.

Even the early E-2 early warning aircraft does not have the ability to filter ground clutter. It only filters out the clutter on the sea surface. It has gradually developed in the later period. The electronic technology of Xiong and the West has at least ten Years gap, so they simply can't solve this problem.

Hearing Shuchikov’s words, Qin Guan frowned: "Well, if this is the case, if we only process the radar antenna, it is not enough. The processing system needed in the later stage is also very large. Even relying on our electronic capabilities, it has only just completed the integration and is stuffed into the body of this kind of aircraft. Therefore, only the radar antenna is changed, I think it is not very useful."

"If you add a post-processing system, we cannot export directly due to certain restrictions. If you want to modify, you can only send the body to us for modification in our country. This is also what we give to others. A common plan for the country to modify early warning aircraft."

For example, the Holy Nation has ordered a batch of early warning aircraft from Han. The C-130 body of the Holy Nation is directly adopted by Han. It must be modified by them who flew the aircraft over.

Now, when Qin Guan comes to Xiong Country, he is definitely not to promote friendship and learn from Lei Feng. What Qin Guan has to do is to build a good relationship and wait to pick fruit later.

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 be improved in Han country. In this way, the other party has to take the machine over. Then, It can be dragged to the disintegration of the bear country. At that time, can the plane go back?

It’s useless to go back. The empire has disappeared, and the other side is left with an aircraft carrier that took off. This kind of early warning aircraft can’t fly, and it’s useless if you want it. Just stay and test it for Han Up.

Perhaps it can be sold to a third country, such as Chicken Country. Their carrier-based early warning aircraft was purchased from Eagle Country. It is cheaper and sold to Chicken Country? Those arrogant Jiguo people don't know what kind of psychology it will be.

The conditions put forward by Qin Guan made Shuchikov very difficult to accept. Yes, they need advanced radar equipment, but let’s say that this kind of aircraft is sent to Han, and Han will install radar equipment. Who developed it, or was it a product of their Yakleev Design Bureau?

However, if you only use a radar antenna, it seems really inappropriate, because those post-processing circuits are indeed lagging behind.

Shuchikov can't be the master.

"Right now, your body hasn't been built yet?" Qin Guan continued: "You can build the body first, leaving enough space and power supply. We can also slow down the radar thing first, maybe , Will our exchanges go further in the future?"

Of course Qin Guan knew what he was embarrassing for. Under such circumstances, he must hesitate. How could he hand over this kind of aircraft to Han for modification, but now he is laying the groundwork for the future. Then Jacques 141, who would have thought it was a power pack made with Han Guo?
