Chapter 337 Ye Gong wants to lie down

However, if you ask him questions, he is a little at a loss, mainly because he has no concept of it. It's like asking an ordinary person to ask questions about quantum mechanics, he will definitely not get to the point.

The core functions of the electronic system itself are still in a mess and there is no clear solution, not to mention electronic countermeasures. Although I can understand what electronic interference means, I don’t know what goes deeper.

So Engineer Ye made a request very embarrassedly: "Mr. Gao, can you first explain to us the relevant concepts of electronic interference?"

Don't bother two people with one thing, just tell me everything.

Gao Zhendong was stunned, and immediately worked at full speed, searching his mind for relevant things in order to form a systematic outline.

At this time, Gao Zhendong's state was probably like "Wait, let me figure it out."

Seeing that he was thinking, Ye Gong was not in a hurry and waited quietly with his men.

After thinking for a while, Gao Zhendong spoke slowly: "Engineer Ye, this is what I think. You should understand better than me that with the increasing maturity of radar, anti-ship missiles and other equipment."

Gao Zhendong began to tell the story, which lasted for about ten minutes.

".In summary, in the future battlefield, both the attacker and the defender will inevitably face fierce electronic confrontation. For the attacker, anti-interference technology will be indispensable, otherwise it will face the dilemma of being invisible and intangible; and for the defender, electronic interference and electronic confrontation are also important means to improve its survivability."

"Therefore, electronic countermeasure technology should be considered as one of the core capabilities of the equipment's electronic system, from a system and system perspective, at the beginning of the design and integrated into the command and control system of the equipment."

This requirement of integration from the womb seems simple, isn't it just transferring data? But in fact it is very difficult. Information integration is not that easy, and electronic warfare is not as simple as data fusion.

Let me put it this way. According to what Gao Zhendong knew in his previous life, if there are still dozens of countries that can build airplanes, cannons and missiles, then there are only a few that can develop good electronic warfare systems. Among the three permanent members of the UN Security Council, there are only these few, and one of them can only be considered halfway.

What is meant here is to improve the entire electronic warfare system, not just having an electronic warfare pod or something that is processed through technology transfer from Sanchang.

Electric Pomegranate, Howler: You are right!

Engineer Ye and the others understood what was said and comprehended it completely. They were born in this field but were a little slow in thinking. However, as long as someone gave them some pointers in advance, they could get into the state very quickly.

"Chief Engineer Gao, now that you've said that, I understand. We also had a vague idea of ​​some of these things when we were working on ship fire control, but we never expected that they would form such a core point of the equipment's electronic system in such a deep and clear way."

Sure enough, what Lao Qi told Chief Engineer Gao not to believe if he “didn’t understand” made so much sense.

Gao Zhendong smiled and said, "I may be a bystander who sees things more clearly. After all, when it comes to shipborne electronic systems, I only need to speculate. You have a lot more things to consider based on technical reality and environment."

Damn it. I still applied it. This formula is really magical.

Engineer Ye shook his head. "Haha, I can't think of it, that's the fact. President Gao doesn't need to comfort me. You can come up with such a set of ideas through your thinking after work. We are specialized in this but we can't think of it. It's probably because we don't have the ability."

Seeing that Engineer Ye was determined to carry out self-criticism, Gao Zhendong felt uncomfortable responding and just laughed.

Engineer Ye didn't care. It was no big deal to ask for advice when doing work.

I'm asking questions for my motherland, which is much better than the Citigroup guys' "I steal oil for my motherland". No, no, they have even started stealing food.

"Mr. Gao, I heard from Lao Qi that you introduced to him the various interference methods you were considering, but he was not an expert in this field and there were some procedural problems at the time. So there are many things that he did not remember clearly and did not explain to me clearly. I would like you to introduce them to me again."

For him, as long as he knows the definitions and concepts of various methods, he can get a lot of work done without going into the technical details.

Gao Zhendong nodded: "Well, no problem. In my opinion, the main principles of electronic interference are divided into active interference and passive interference. Among these two types of interference, I think there are four more feasible methods."

Gao Zhendong began to explain to Engineer Ye and the others the electronic jamming technology he knew.

Active/passive is sometimes defined as active/passive, but from a technical point of view, the former is more appropriate, just like AESA/PESA in phased array radar. As time goes by, active/passive is still the more commonly used name.

However, Engineer Ye and his team obviously are not bothered by this matter now. Instead, they are attracted by the two principles and four methods that Gao Zhendong presented at once.

If the two principles of active and passive are conceivable to anyone who works in RF, then the four methods show that Chief Engineer Gao has already given in-depth thought in this regard.

But what Gao Zhendong wants to say is much more than that, and what comes next is even more shocking.

"Of the four methods, three have two styles or modes, and one is a full-range, long-term method." Hmm? Seven weapons, right?

These words made Engineer Ye's scalp tingle. This was no longer called thinking, this was deep research. The reason why there were no results was probably mainly because they were from a steel company, unlike himself, who did not have the conditions for research in this area, otherwise results would have been achieved long ago.

But this was not the end. Gao Zhendong's next words made him give up thinking completely.

"In the search and tracking phases of an anti-ship missile attack, these seven patterns can be combined into more than 7 electronic jamming combinations."

The mood of Mr. Ye and his colleagues at this time was somewhat similar to the feeling they would have in the future: "Forget it, I'm tired, let's just destroy it." It was no longer possible to describe it in words. They just wanted to throw down their pens and lie down.

After a period of emptiness, there followed a huge feeling of joy. It was stable!
Although the seven styles mentioned by Chief Engineer Gao may all be his imagination and cannot be realized with the existing technical conditions, as long as several of them can be realized, it will greatly enhance the survivability of the ship.

If we can take the countermeasures to these means into consideration in advance, with both offense and defense, then need we say more about the effect?
"Mr. Gao, please enlighten me, please enlighten me."

Engineer Ye was very anxious because he had only heard the list but had not seen the actual goods. Although the person was right in front of him and he could not run away, his anxious mood was out of control.

As for the people he brought with him, they all looked at Gao Zhendong as if he were a god. What was this big shot doing in a steel company? It was simply a joke.

Seventeenth Ministry of Machine Building: What else do you say?

Gao Zhendong smiled and said, "Don't worry, Mr. Ye, I'll tell you step by step."

Mr. Ye stared at him intently—Just tell me!

Looking back over the next few decades, until Gao Zhendong's time traveling, there were two main types of active electronic jamming: shipborne active jammers (active electronic warfare systems) and outboard active decoys.

The former is easy to understand. The jammer is installed on the ship. Relying on the conditions of the ship, it can issue an alarm based on the local electromagnetic wave signal situation and emit electromagnetic waves to suppress, deceive and interfere with the enemy.

The benefits of this method are self-evident, with a wide range of adaptability, large interference power, high alarm sensitivity, long distance, multiple interference methods, etc. As for the disadvantages, needless to say, the only disadvantage of expensive things is that they are expensive. Of course, adaptability is also a disadvantage.

The latter can be imagined as installing a jammer on a rocket and firing it to interfere with the enemy. However, due to its size, this type of jammer is generally only used as a false target bait.

This thing is more adaptable than the former, but its means are not as diverse as the former.

"Well, I understand. What do you mean by style?"

There are two main types of interference styles of shipborne active electronic warfare systems: noise suppression and deception interference.

Noise suppression is commonly known as great power to achieve miracles, using high-power noise to directly drown out the electromagnetic signals of the attacker. People who work in information should know a network attack method called DDOS attack, which is a bit similar to it. There are many ways to implement noise suppression, each with its own advantages and disadvantages.

Deception jamming is to generate false target signals of ships to deceive enemy radars, causing them to track the false targets instead, thereby achieving the purpose of protecting themselves.

The outboard active decoy is similar. It has two styles: dense false target suppression and multiple false target deception. This thing is not that one decoy can only simulate one false target, but that one decoy can simulate multiple false targets. One decoy can be transformed into hundreds of ships when it is launched.

"Mr. Gao, your ideas are so clear. If you hadn't mentioned it, I wouldn't have remembered it. Now that you've mentioned it, I feel like some of the things in it can be done right now."

Mr. Ye took notes while praising the works endlessly.

Gao Zhendong smiled and said, "Engineer Ye is planning to make a noise suppression electric warfare system?"

Engineer Ye nodded: "Director Gao, you understand. This is the most mature condition right now."

For electronic warfare systems, fake targets have relatively high requirements for system hardware, namely the radio frequency system, system software, namely signal processing control, and theoretical basic research. It is still difficult to do it at this time, even with the DJS-60D.

The outboard decoy looks simple, with an electronic warfare antenna and a rocket, but the size of this thing limits everything, and it is not that easy to make.

So under current conditions, the most realistic active electronic jammer is the suppression-style electronic warfare system. In any case, the power support that a warship can get is much stronger than that of a missile, and this method does not seem to have very high requirements for other things except power.

One force can defeat ten skills, and great strength can create miracles.

Gao Zhendong smiled and said, "Well, this method is indeed the most realistic. If you want to do this, I can also give you some suggestions."
