Chapter 550: If you can laugh tomorrow, you are awesome

So when this comrade saw that this circuit could also multiply the frequency, he immediately came up with an idea.

Hearing his words, Gao Zhendong shook his head: "This can be used for frequency doubling, but the accuracy and overall performance are not the best."

Now, let alone the comrade who proposed it, everyone else's interest was high. Since Chief Engineer Gao could say that this was not the best, it meant one thing - he must know something better!

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 the same: Mr. Gao, please tell us about it.

Gao Zhendong then realized that this thing was not easy to deal with at the moment, and it was like trying to find a sword by carving a mark on the boat*2.

Phase-locked loop, it's your turn!
However, Gao Zhendong doesn't need to explain this himself. He learned the phase-locked loop from Lao He when he was working on the laser rangefinder at the Caotuo Factory.

At this time, it was getting late and there was no need to waste any more time. Some people could say that Gao Zhendong was just being lazy.

"It's better to use a phase-locked loop than an analog multiplier. I have already handed over the principle of the phase-locked loop circuit to comrades in other units. Their frequency requirements are lower than yours, but the circuit principles are the same. And they already have practical successful application experience. So, I will talk to the committee later, get permission, and then notify you to go directly to them, so that you can see both the principle and the practice."

Several comrades were very happy and reaped a lot of benefits. What a great harvest!
Gao Zhendong was still not satisfied: "Unfortunately, the conditions are limited now. Some of my better ideas cannot be realized for the time being. But wait a while, maybe the conditions will be there."

Gao Zhendong had no idea of ​​making a better large-scale PD (pulse Doppler) radar for early warning aircraft.

The performance of the Conus-like aircraft is sufficient for now. As long as the ground clutter problem can be solved, its presence in the air will be a wall that enemy aircraft will find difficult to pass through quietly.

Building a new large-scale PD is difficult, time-consuming, costly, and requires a complex system with many missing technologies. It will take a long time to build it.

Since they are available, we should try to improve them as much as possible. Nowadays, there is no such thing as stealth or super maneuverability in aircraft. With good aircraft and good missiles, they will be a deadly threat as long as they are discovered.

Besides, if there are any problems with the Conus Tu-4, Gao Zhendong can still find some solutions, which can also greatly reduce the development cycle of the early warning aircraft.

Things like early warning aircraft don't need to be particularly good, as long as they are qualified. Having one and not having one are two completely different situations.

The better idea he mentioned was not aimed at the radar on the early warning aircraft, but at something else.

However, when other comrades heard this, they felt itchy again.

What else? Forget it, don't be greedy, don't be greedy, digest these first, comrades still know the truth of aiming too high and biting off more than you can digest.

Since Chief Engineer Gao has brought it up on his own initiative, 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 gathered at this branch venue to explain the issue of ground clutter processing in a relatively thorough manner before returning to the main venue.

The group walked into the main venue and took their seats again in full view of the public.

The Air Force immediately looked at several representatives in the radar field: "Comrades, what's the situation?"

The comrades working on radar were in high spirits. One of the most senior representatives laughed out loud, "It's possible! It's possible! Chief Engineer Gao has given us a good lesson. His ideas have a solid foundation, clear principles, ingenious structure, and feasible circuits. This class is not a seminar but a teaching class. We have learned a lot from Chief Engineer Gao. We should be able to deal with ground clutter."

Everyone, including the leaders of the Defense Work Committee, showed joy on their faces. This was great news. With this foundation, it could be said that the airborne command post could be launched.

Moreover, this conclusion is not just a question of whether the air command post should be put into use, but involves all low-altitude detection. This technology may not only be used there. Can other radars be used? Thinking about it this way, the space is huge.

The leader of the Air Force said to the leader of the Defense Work Committee happily: "Old X, do you think we should give this 'Air Command Post' a name?"

The leader thought, yes, now that it has come to this, it is time to give it a name. Otherwise, when the project is set up later, it will still be called the "Air Command Post", which seems not very formal.

"Well, let's all think about a name?" the leader of the Defense Work Committee said with a smile.

As soon as these words were spoken, everyone showed off their magical powers.

There are command aircraft, radar aircraft, radar patrol aircraft, warning aircraft, special electronic aircraft and so on, which are numerous and varied.

But after thinking about it, he always felt that it was still a little lacking. The leader of the Defense Work Committee thought of Gao Zhendong. This comrade's ability in naming was very poor compared to his other abilities, but he occasionally had his moments of glory. Why not let him try it today?

"Comrade Zhendong, you were the first to propose this plane. Come on, tell me what we should call it." Gao Zhendong, who was trying to retreat, saw that he was called and had no choice but to show his head. Fortunately, he had a stable name to use.

He pretended to think for a while before speaking: "I think we should call it an early warning command aircraft."

The name sounds ordinary, but the good thing is that it encompasses all the functions and features of this aircraft.

"Early warning? Command? Well, this early warning is used well. It is a pre-alert. It fully demonstrates that this aircraft can stand high and see far, and its radar is powerful. It can detect air situations in the early stages." The comrade from the Air Force laughed.

It is said that all good designs look the same. With a suitable name, everyone can think of the same idea.

In the early days, early warning aircraft were called "early warning aircraft". This "early" does not mean that the era in which it was located was the early stage of the development of early warning aircraft, but that it can begin to play a role in the early stage of air situations.

But if we focus on grammar, the words "early" and "warning" seem to be grammatical errors?

"Well, early warning and command, all the characteristics of this aircraft are incorporated into it." The leader of the Defense Work Committee laughed.

Gao Zhendong added: "These are actually two functions, or two steps. The first step is to achieve early warning, and then to achieve command."

In the early days of early warning aircraft, the early warning function was realized, but the command function was relatively weak. Later, when the electromagnetic environment became more complex, the command function was fully integrated.

Another reason is that the earliest early warning aircraft were not very big and could only be equipped with a radar. As for command, they could not accommodate so many people and equipment.

As for the oddball among the early warning aircraft, John Bull's "Gannel", there is no need to mention it. Even if it can be equipped with commanders, these people would be embarrassed to go up and command, because this damn thing is really ugly.

——John’s aircraft has an appearance value of one stone, the Spitfire, Hurricane and Mosquito each have four stones, and the rest are short of two stones!

Gao Zhendong's words were actually a hidden reminder that this aircraft is not just equipped with a radar, but also needs to be equipped with command equipment and personnel. Relatively speaking, the Tu-4 should be the aircraft with the best modification conditions at hand at this time, and it would be a waste if it is not used well.

The Air Force and the Defense Working Committee discussed it in low voice for a few words and decided that this aircraft would be called the "early warning and command aircraft" and that they must develop it and develop it well. As for the specific details, they would be discussed later and not in this meeting.

"Comrades, thank you for your hard work. It's getting late today, so this seminar will be temporarily adjourned and will continue tomorrow." After saying this, the leader of the Defense Work Committee looked at his watch and announced loudly.

Gao Zhendong and his team spent quite a while discussing the circuit. Although it seemed like only a few words were spoken, it actually took up most of the afternoon. Otherwise, Gao Zhendong would not have thrown the issue of the phase-locked loop to Lao He from Caotuo Factory.

There are not many opportunities to bring together elites from all walks of life. If we have to have one, we should have a thorough gathering. One day is definitely not enough.

While having dinner together, the leader smiled and said to Gao Zhendong: "It seems that you came prepared today. You are very well prepared."

He knew that Gao Zhendong had a lot of ideas about air force equipment, but he didn't expect it to be to this extent. He even delved so deeply into such a relatively advanced and obscure aspect as radar ground clutter processing.

Gao Zhendong smiled and said, "As for signal processing, if you know a little bit about it, you will think more about it."

"Hahaha, you don't have to be so modest. You've already done more than that."

A comrade from the Air Force also came over and said, "Comrade Zhendong, thank you for helping me with the ground clutter processing problem."

Having already tasted the sweetness of the Tu-4 special aircraft filling in the air blind spots, they had this experience and followed Gao Zhendong's idea of ​​moving the 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 heavy blow to them.

It can’t be seen when it is placed on the ground, and it still can’t be seen when it flies into the sky. This shows... Captain Jia’s value is still rising.

They knew very well that they were at a loss as to how to solve this problem, but after Gao Zhendong and the comrades working on the radar spent an afternoon whispering in a small dark room, they announced that they were confident that the problem would be solved. Who would believe that it was not Gao Zhendong's fault?

Gao Zhendong responded with a smile and thought to himself, don't thank me now. If you can still smile at the meeting tomorrow, then it will be considered that you are really thanking me.

I guess there are some ideas that would make the Air Force jump up and down even if Gao Zhendong expressed them, let alone whether they agreed or not.

But for Gao Zhendong, there were some ideas that he had to express, and he no longer cared whether the Air Force was happy or not. Who knows, they might be even happier after hearing them.
