Chapter 533: Determined

The friendly relations between the holy country and the Han country are reflected in many aspects.
It can be said that the holy country can have what the Han army has, and what the holy country has can also be handed over to Han for study. For example, after the holy country was equipped with F-16s, it once gave one of them to Han China studies went.
A few years ago in the Holy Land, a Boeing 707 passenger plane crashed. Experts from Han Guo went to study for a year or two. Later, these experts formed the Yunshi R&D team.
Now, Qin Guan finally decided to do a big job, F404 has been matched, isn't there just one avionics left? Isn’t it just that there are advanced radars that cannot be solved by oneself? It's easy to say, oneself now get it out!
Qin Guan can take out various radar data from the weapon data cemetery, but this cannot appear out of thin air after all. What is needed now is just a sample. Before that, the Han country had never officially contacted advanced The radar prototype.
Now, it depends on whether the other party is willing to take risks.
After all, if the Han country has developed an advanced radar, the West will pursue it, and it will definitely pursue those who came to the holy country, not the holy country, who is it?
When the time comes, the Holy Nation will shake his head and refuse to admit it. What can they do to the Holy Nation?
In history, the Super Seven project, only round-trip negotiations, has been tossed for nearly ten years, and even at the end of the negotiations, the Holy Nation has withdrawn from the project, which is 6611, and finally decided to self-finance and develop this aircraft. Qin Guan knew the hardships.
Later, when it came out, the Holy Nation joined in again. There were too many bumps in the middle.
Now, Qin Guan would not watch such a bumpy ride happen again. Simply solve the avionics! Solve the problem of avionics, then the engine is left!
This engine problem must be resolved within five years. After five years, this aircraft will have no export barriers. At that time, in 1984, the Su-27 had just been equipped with Xiong Country. The country uses backward second-generation machines, and the demand for replacement is great.
Qin Guan finally made up his mind.
As for Qin Guan's statement, the other party was quite cautious: "Can Han be copied?"
This is sophisticated electronic technology. Right now, even Niu Guo doesn't have the ability to deal with advanced radar. Han Guo has this ability?
"We have to try. You should know our breakthroughs in general-purpose processors. We have already begun to stock up on technology. With the help of reform, we will surely soar into the sky." Qin Guan said.
Han Guo’s self-produced Loongson-1 general-purpose processor has advanced performance and has been spread all over the world. It is said that even Eagle State’s chip companies are in a hurry and want to catch up.
In terms of electronic systems, maybe Han Guo can really do it?
"If we can get in touch, can you come to the holy country to study?" the other party said.
The risk of getting the radar to Han country is too great, it is better to let them come to the holy country to study, so the risk is smaller.
Qin nodded in view: "No problem."
After going back, I went to the domestic radar station to check, this shortcoming should be made up!
Qin Guan couldn't wait any longer.
"As long as the radar is handed over to us for research, we will try to imitate it within three months," Qin Guan said.
Three months is quite against the sky, but at the same time, the time should not be too long, too long, too many variables, it is better to rely on yourself.
Qin Guan thought secretly.
In fact, this research on the radar of the Eagles is just an excuse. After returning, I will get the radar of the J-10 directly!
Suddenly, in Qin Guan's mind, something came to mind again, yes, in terms of foreign cooperation, besides engaging in the radar of the Eagles from here, he has a new choice.
At the beginning, the development of the J-10 had too many connections with the "Lion" fighters of the Kingdom of David. When the time is right, you can also go to the Kingdom of David to learn from it.
At that time, there will be no need to drag down the holy nation. It is the technology from the kingdom of David. What can the people of the Eagle nation do with themselves?
In this way, the model you have imitated has nothing to do with the AN/APQ-159 radar system, and it will not arouse outside suspicion.
Qin Guan’s weapon system can bring in advanced weapons at any time, and the information is not a problem. As for the chip in the electronic system, due to the ability to resist electromagnetic pulses, it will not use particularly advanced technology. The production line is fully usable.
The main thing is probably the dual-mode grid-controlled traveling wave tube in the radar system.
When someone talks about radar systems, they are very clear, saying that Xiong Guo has been engaged in electronic tubes and is too backward, while the Western world has begun to enter the era of integrated circuits and is advanced.
In fact, for radars, in addition to phased array radars, ordinary pulse Doppler radars must have a component similar to an electronic tube, called a traveling wave tube.
It is used to radiate electromagnetic waves, and its performance directly reflects the performance of the radar. As for the front panel slot radar antenna, the electromagnetic waves of the traveling wave tube are emitted through this antenna.
The so-called dual-mode grid-controlled traveling wave tube refers to that it consists of two control grids. When only the outer ring grid is working, it can emit pulses with a high duty ratio. This is the high pulse repetition rate (PRF) mode. When working together, the pulse can be modulated to obtain medium and low PRF modes with low duty cycle and high peak value. In this way, the radar is equivalent to having two transmitters, which greatly improves the performance of the radar.
At present, Han Guo’s radar can't be dealt with with only a single pulse Doppler radar, and modern airborne radar functions are increasing day by day. In order to meet the multi-function requirements of radar, the radar needs to use multiple pulse PRF, which means that when the radar detects the whole In the airspace, it is required to use different PRFs alternately to overcome the limitations of different PRFs. It can work in both medium and low PRF modes with high peak rate and low working ratio, and high PRF mode with high working ratio. In a sense, only after adopting dual-mode grid-controlled traveling wave tube, the airborne radar has real multi-function characteristics.
This thing can be obtained from the Kingdom of David, and the processing technology of the flat slot radar antenna can also be obtained from the Kingdom of David, so that it will not arouse suspicion.
Yes, just do it!
Qin Guan has made up his mind, and after returning, he will completely solve the radar problem!
Phased array radar is still not available, but advanced pulse Doppler radar must be developed, and the supporting project for our own Raptors must be steadily advanced.
I don't know if the Raptors can make their first flight by the end of this year.
