Chapter 550: Only those who can laugh tomorrow are really awesome
So when this comrade saw that this circuit could double the frequency, he immediately made up his mind.
Hearing his words, Gao Zhendong shook his head: "This can be used for frequency multiplication, but the accuracy and comprehensive performance are not the best."
Don't mention the one who proposed it now. Comrades, everyone else's interest rose. Since Chief Engineer Gao can tell that this is not the best, it means one thing - he must know a better thing!
For them, the frequency source, like the previous analog multiplier circuit, is the core basic circuit of high-frequency digital circuits such as radar, so their interest is high and their demands are consistent: Mr. Gao, tell me .
Only then did Gao Zhendong realize that this thing was not easy to play with now, so he turned around and tried to find a sword*2.
Phase locked loop, it’s your turn!
But there is no need for Gao Zhendong to explain this himself. He learned the phase-locked loop from himself when Lao He and others in the grass mop factory were working on laser rangefinders.
At this time, it is getting late, there is no need to waste time anymore, some people can say that Gao Zhendong himself is lazy.
“It is better to use a phase-locked loop than to use an analog multiplier. I have handed over the principle of the phase-locked loop circuit to comrades in other units. Their frequency requirements are lower than yours, but the principle of the circuit is the same. And they already have actual successful application experience. In this way, I will talk to the committee later, give permission, and then inform you to go to them directly, and you can see both the principle and practice.”
Several comrades are very happy, they have gained a lot, they have gained a lot!
Gao Zhendong is still unfinished: "Unfortunately, the conditions are limited now, and some of my better ideas cannot be realized for the time being, but after a wait, maybe there will be conditions."
Gao Zhendong did not The idea of getting a better large PD (Pulse Doppler) radar on an early warning aircraft.
The performance of the imitation Connus is enough for now. As long as it can solve the problem of ground clutter, its existence in the air will be a wall that enemy aircraft cannot pass through quietly.
Building a new large-scale PD is difficult, time-consuming, costly, has complex systems, and lacks many technologies. It will take years and months to complete it.
Since there is something available, try to improve it and use it as much as possible. There is no such thing as stealth or super maneuverability in aircraft these days. With good aircraft and missiles, as long as they are discovered, they will be a fatal threat.
Besides, by imitating the Konnus Picture-4 above, if there is any problem, Gao Zhendong can still find some solutions, which can also greatly reduce the development cycle of the early warning aircraft.
Early warning aircraft don’t have to be particularly good, as long as they are qualified, having them or not having them are completely two different situations.
The better idea he mentioned is not actually aimed at the radar on the early warning aircraft, but something else.
However, when hearing these words in the ears of other comrades, I felt itchy and unbearable.
besides? Forget it, you can't be greedy, you can't be greedy. Let's digest these things first. Comrades still know the truth of aiming too high and being greedy and biting off more than you can chew.
Since Chief Engineer Gao took the initiative to bring it up, he will naturally bring it up when the conditions are ripe.
Since he didn’t continue talking, there was no point in asking, and it was also a bit inappropriate.
A group of people in this branch venue had a more thorough explanation of the ground clutter treatment before heading back to the main venue.
The group walked into the main venue and sat down again in full view of everyone.
The Air Force's eyes immediately turned to several representatives in the radar field: "Comrades, how is the situation?"
The comrades engaged in radar were in high spirits, and one of the representatives who should be the most senior laughed and said: "There is a way! There is a way! Chief Engineer Gao gave us a good lesson. His ideas have a solid foundation, clear principles, ingenious structures, and feasible circuits. This class is not a seminar, but a teaching class. We will start from Chief Engineer Gao has learned a lot here. He should be able to deal with ground clutter."
Everyone, including the leaders of the Defense Work Committee, looked happy. This is great news. With this foundation in place, it can be said that this air command post can be launched.
And this conclusion is not just a matter of whether the air command post can be launched, but involves all low-altitude detection. This technology is not necessarily only used there. Other radars can The ____ does not work? If you think about it this way, this space is quite large.
The leader of the Air Force said happily to the leader of the National Defense Working Committee: "Old X, look, should we give this 'air command post' a name?"
The leader thought, yes, it has already reached this level. Is it time to give it a name? Otherwise, when the project is established later, it will still be called "Air Command Post", which seems not very formal.
"Well, let's all think about it and give it a name, right?" the leader of the National Defense Work Committee said with a smile.
As soon as these words came out, everyone crossed the sea and showed their magical powers.
There are command planes, radar planes, radar patrol planes, warning planes, special electronic machines, etc., and there are all kinds of them.
But after thinking about it, I always felt that it was not even interesting. The leader of the Defense Working Committee thought of Gao Zhendong. Compared with his other abilities, this comrade’s ability to name names was very poor, but occasionally there were shining moments. , how about letting him try it today?
"Comrade Zhendong, you were the first to propose this plane. Come on, come on, tell me what to call it?" Gao Zhendong, who was trying to move back, saw that his name was called, and had no choice but to Fortunately, he has a solid name to use.
He pretended to think for a while and then said: "I think it should be called early warning command aircraft."
The name sounds ordinary, but it is good. Fortunately, all the functions and features of this aircraft are included.
"Early warning? Command? Well, this early warning is used well. The early warning fully illustrates the characteristics of this aircraft that can stand high and see far, has high radar power, and can detect air conditions in advance at an early stage. "The comrade in the Air Force laughed.
Otherwise, all excellent designs have the same look. With a suitable name, everyone can think of it.
In the early days, early warning aircraft were called "early warning aircraft". This "early" does not mean that it was in the early stage of the development of early warning aircraft, but that it could detect early warning aircraft in the early stages of air conditions. , it starts to work.
But if you are obsessed with grammar, this "early" and "early warning" seems to be a grammatical error? .
“Well, early warning and command are all the characteristics of this aircraft.” The leader of the National Defense Work Committee smiled.
Gao Zhendong added: "This is actually two functions, or it can be regarded as two steps. The first step is to realize early warning, and then to realize command."
In the early warning aircraft, the early warning function was realized, but the command function was actually relatively weakened. Later, when the electromagnetic environment became more complicated, the command function was fully integrated.
Another reason is that the earliest early warning aircraft were not very big, so it would have been nice to install a radar. As for the command, they really could not accommodate so many people and equipment.
As for John Bull's "Gannet", a strange type of early warning aircraft, let alone it. It is estimated that even if they can act as commanders, these people will be too embarrassed to go up and command. This piece of shit is too Ugly.
——John's plane is worth a stone's throw, the Spitfire Hurricane Mosquito each has four buckets, and the rest is worth two buckets!
What Gao Zhendong meant when he said this was actually an implicit reminder that this aircraft is not only equipped with a radar, but also has command equipment and personnel. Relatively speaking, the Tu-4 should be the aircraft with the best modification conditions at this time. If you don't make good use of it, it will be in vain.
The Air Force and the National Defense Work Committee discussed it in a low voice and decided that this aircraft would be called an "early warning and command aircraft". It had to be built, and it had to be done well. As for the specific details, we will talk about it later. This meeting I won’t discuss it above.
"Thank you for your hard work, comrades. As it is getting late today, this seminar will be temporarily adjourned and will continue tomorrow." After saying this, the leader of the National Defense Work Committee looked at his watch and announced loudly.
Gao Zhendong and the others spent a lot of time discussing the circuit. They only talked about a few words, but in fact they spent most of the afternoon. Otherwise, Gao Zhendong would not have thrown the phase-locked loop matter to It's over to Mr. He from the straw mop factory.
There are not many opportunities to bring elites from all walks of life together. If you want to open it, open it thoroughly. One day is definitely not enough.
While having dinner together, the leader smiled at Gao Zhendong and said, "It seems that you are well prepared today. You are very well prepared."
He knew that Gao Zhendong had a lot of ideas on air force equipment, but he didn't expect that he would go so deep into such a relatively in-depth and obscure aspect as radar ground clutter processing.
Gao Zhendong smiled and said: "Signal processing, if you understand a little bit, you will think more."
"Hahaha, you don't have to be humble, you are already more than just comparing Much more."
Comrades from the Air Force also came over: "Comrade Zhendong, I have to thank you for this problem of ground clutter handling."
I have already tasted the Tu-4 special effects. They had the advantage of filling blind spots in the air. With this experience, they followed Gao Zhendong's path of moving a large radar into the sky. The more they thought about it, the more they thought it was a good thing.
Therefore, the problem of ground clutter is undoubtedly a blow to them.
You can't see it on the ground, and you can't see it even if you fly in the sky. No... Captain Jia's gold content is still rising.
They knew very well that after Gao Zhendong and the radar comrades muttered in a small dark room for an afternoon about this problem that they were originally helpless to solve, they announced that they were confident that this was not Gao Zhendong's. Who believes the reason?
While answering the conversation with a smile, Gao Zhendong thought to himself, don’t thank me now. If you can still laugh at the meeting tomorrow, then you are really thanking me.
I guess he has some ideas. Even if Gao Zhendong says it out, the Air Force will have to jump in, let alone whether he agrees or disagrees.
But for Gao Zhendong, he must say something about some of his thoughts, and he no longer cares about whether the Air Force officers are happy or not. Maybe they will be happier after hearing this.
