Chapter 310 The strongest electronic warfare system, CHL-1106!

Meanwhile, Chengdu.

In order to solve the problem as quickly as possible, Chen Nian had to temporarily put aside the preparations for metal hydrogen and devote his energy to the research and development of electronic warfare equipment.

According to his plan, the new generation of electronic warfare equipment will be directly improved on the basis of 14 active electronic warfare equipment CHL-906, spanning to the most advanced CHL-1106 equipment 15 years later.

For him, this is not difficult, even without the help of the system, relying on the knowledge and technology accumulated over a long period of time, he can slowly figure out the technical documentation of CHL-1106 in a month or two .

From a certain point of view, it is not so cost-effective to use the source point to analyze CHL-1106 when there is a system.

But what Chen Nian needs to consider now is not cost-effective, nor cost-effectiveness, but how to use the fastest speed to solve the current predicament.

Therefore, without any hesitation, he directly obtained the CHL-1106 document through the system, and output it on paper in the shortest possible time.

The experts from the 14th Institute had already flown to Chengdu to wait, and after getting Chen Nian's technology, they started discussions non-stop.

In the conference room, Liu Yongtan wore presbyopic glasses, habitually turned over the materials in front of him with his hands stained with saliva, and whispered while watching:

".With phased array radar plus digital array technology, the antenna composition of this set is not much different from the current CHL-906. Gallium nitride components are also available. Basically, purely from the hardware point of view, there is no big difference. question."

"The current problems are mainly in two aspects. The first one is the artificial intelligence and machine learning algorithms mentioned in it."

"We don't have any experience in this area, and we don't have any reference objects."

"Even if the code is written, problems will continue to be encountered in the subsequent training process."

Liu Yongtan, as a scientist of the older generation, of course cannot be a "veteran" as some people in the society think.

On the contrary, due to his rich experience and super high IQ, he is much more sensitive to new technologies than many young scholars.

Therefore, when the neural network machine learning algorithm first appeared, he had already realized the importance of this technology in electronic countermeasures.

Using the power of machines to analyze the working mode of the opponent's radar and analyze their pulse characteristics is not known how many times faster than manual analysis.

If it can be realized, the current electronic countermeasure technology in the world will inevitably take a big step forward.

Of course, the only problem, as he said, was that the technology hadn't been tried before.

In the past, I crossed the river by feeling the eagle sauce, but this time I can only cross the river by feeling the stones.

It is very difficult to reach the predetermined level in a short period of time, and his confidence is not enough.

Hearing his words, Chen Nian nodded and said:

"This problem is really difficult to solve, but it doesn't matter. We don't have to reach a completely perfect level at the beginning. We can practice and improve slowly."

"The core of this system is to use high-power antennas to directly cover the opponent's echoes outside the defense zone, and use ultra-high frequency and sub-high frequency electromagnetic waves alternately to create false signals, so as to achieve our tactical goals. "

"To put it bluntly, what we have to do is to first blank out the opponent's radar, and then point out the bright spots on the blanked radar, making them think that those bright spots are flying objects that have been burned through."

"If we do this, our goal will be basically achieved."

The "radar burn-through" mentioned by Chen Nian actually refers to the situation that "because the flying object is too close to the radar, the radar echo signal strength exceeds the electronic interference signal strength, resulting in the flying object being still detected in the interference environment".

The principle is simple.

Electromagnetic waves propagate in space, and the atmosphere absorbs the energy of electromagnetic waves. The longer the distance, the more absorption and the greater the attenuation of electromagnetic waves.

In the process of jamming, the ground radar is also synchronously detecting.

If the distance between the jammer and the radar is A, then the electromagnetic wave emitted by the radar reaches the aircraft and travels a distance A, and then reflects from the aircraft back to the radar and travels a distance A, that is to say, the echo signal travels a distance of 2A.

But the jamming signal sent by the jammer only traveled the distance A to the radar.

Although the distance is only doubled, in fact, this ordinary mathematical formula has a huge impact.

In the interference equation, when the distance becomes 1/4 of the original, to achieve the same interference effect, the interference power only needs 1/16 of the original.

However, this situation is only for the jammer itself.

In actual combat, the purpose of interference is to allow fighter jets to penetrate.

Once the echo signal of the fighter jet will be very strong, it may exceed the interference signal power provided by the interference outside the defense zone, and be recognized by the ground radar.

This is the so-called "burn-through".

With this mechanism, the jammer can create the illusion of "burning through after jamming", and make a full set of tricks to achieve a more realistic deception effect.

After hearing Chen Nian's answer, Liu Yongtan sighed softly, and then said:

"But therein lies the problem: we can't sustain that high jamming power."

"As far as the current combat platform is concerned, the two fourth-generation aircraft must first be eliminated and cannot be used."

"J-10? The voyage is too short and the avionics are too weak to support the needs of CHL-1106."

"Yun-8F is currently very difficult to transform and cannot meet the time requirements."

"Judging from the current situation, the most feasible solution is even to change the H-20"

"No need."

Chen Nian looked at Liu Yongtan in surprise, and asked:

"Old Liu, have you forgotten something?"

"It is true that most of the current fighters cannot meet the modification requirements of CHL-1106, but drones can."

"Don't we have Rainbow-9? Directly put CHL-1106 on this platform, no problem at all, right?"

Liu Yongtan shook his head and replied:

"Not good. Our current satellite communication system is not perfect, and the command efficiency is actually not high enough. It is too difficult for a drone to complete complex interference tasks."

"Not to mention anything else, it's already very difficult to achieve remote command alone."

"After all, as long as electronic warfare is turned on, the electromagnetic environment that Rainbow-9 faces must be extremely complex. In this case, how do we control it?"

"No remote control."

Chen Nian shook his head immediately.

"It's good to fly with the drone, let J-20 command CH-9."

"The Yujing project has been going on for so long, and now it has been updated to the fourth generation."

"I think it's time to take advantage of this opportunity to experiment with our 'loyal wingman' plan."

On the other side, Xigong University.

Wang Jiancheng is still working on his mechanical exoskeleton equipment, and it is still his dream of "combat exoskeleton".

Of course, this time he was not out of pure "interest", but was commissioned by the so-called Chengfei to develop an exoskeleton for the official that can adapt to low-intensity security maintenance work.

At the beginning, he thought that this type of exoskeleton was mainly used in the direction of urban police, but as the development requirements were put forward one by one, he gradually came back to it.

There's no way this thing is for the police.

It should be said that it will be used in a "cold weapon conflict event" in a specific environment.

Where would such an event be?

Needless to say, he can understand the answer.

So, after extrapolating this information, his enthusiasm grew.

This is the first time he has participated in equipment that may be directly used in "actual combat"!

There must be no mistakes, and the details of all aspects must be the best.

For two whole months, he spent every day in the laboratory, trying his best to optimize the product at hand.

Although Qiao Mai had said before that she would not invest too much in this project, she would still give Wang Jiancheng some suggestions and technical ideas from time to time.

This helped Wang Jiancheng a lot. Without Qiao Mai, his work efficiency would have been reduced by at least 20%.

But even so, the relationship between the two shows no signs of "easing".

They still dislike each other, and they still maintain purely technical cooperation.

However, the two of them didn't feel embarrassed about it at all. It seemed that they had already learned how to communicate with people according to the standards of the workplace before entering the workplace.

On this day, Wang Jiancheng entered the laboratory as usual, ready to start his debugging work for this day.

But before he finished the first experimental project, the secret phone that Cheng Fei specially configured for him rang.

Wang Jiancheng thought he was here to urge progress, he frantically opened his experiment records, and was about to report according to the records, but the news on the phone made him stunned.

Not news about the exoskeleton project.

It is a project that can be said to be new, but it can also be said to be old.

Neural Network Machine Learning Project.

The "leader" on the other end of the phone made two demands on him.

The first requirement is to continue to improve the flight control system of Yujing 04 and reach usable standards in the shortest possible time.

The second requirement is to develop a new set of artificial intelligence radar algorithms for identifying radar jamming signals of specific frequencies and wavelengths.

For the first request, Wang Jiancheng was not surprised—even in fact, he had already completed most of the work, and the rest was just the finishing part.

But for the second request, he was a little embarrassed.

"Leader, it's not that simple to identify radar jamming signals—maybe machine learning can indeed help to some extent, but the problem is that artificial intelligence training alone cannot achieve the desired effect."

"We need rich data and more accurate probability algorithms to help improve the success rate. To be honest, I'm not very good at it."

When Wang Jiancheng said "very bad at it", he did not mean that he was a scumbag in the field of mathematics. In fact, his mathematics has surpassed the average college student by a lot.

What he really meant was that his current level was not enough to handle the requirements of the mission.

In his opinion, to meet the task requirements, at least in terms of mathematics, it may be at least above the level of a researcher at the Academy of Mathematics and Systems Science of the Chinese Academy of Sciences.

This is obviously not the level he is in, nor is it the level he can reach in the short term.

Hearing his answer, the man on the other end of the phone didn't seem surprised at all.

He just said plainly:

"Task 2 is not for you alone. We have formed a team to tackle this task."

"On the team, you just have to be in charge of the machine learning part."

"As for the field of mathematics, we will also recruit relevant professionals into the group."

"Professional? What level of professional?"

Wang Jiancheng asked subconsciously.

"You don't need to worry about this, but I can guarantee that it is the highest level in the country."

The highest level in the country!

Wang Jiancheng instantly felt relieved.

The fact that the other party can say this kind of thing shows that the preparation must be sufficient.

In that case, you don't need to worry about it.

Don't think too much about it, just play the role you should play.

So he immediately replied:

"Understood the leadership and guaranteed to complete the task!"

"Okay, work hard. After this task is completed, the superior will give you a special reward."

"A special reward?"

Wang Jiancheng murmured, but the man on the opposite side ignored him and hung up the phone directly.

He looked at the phone screen suspiciously, and couldn't help thinking secretly:

Special rewards that can’t be said, so what the hell is it?

Meanwhile, somewhere.

The man asks.

"So, you still refuse to admit that the last electronic interference incident was related to you? I must solemnly inform you that if you continue to refuse to communicate, all subsequent consequences will be borne by you."

The man on the opposite side had a calm expression. He knew that at such a moment, he couldn't show any weakness.

Otherwise, if the other party really catches the flaw, everything will become impossible.

So he opened his mouth and said:

"Yes."

"Everything I just said is a true statement based on facts."

"I must reiterate that we have neither knowledge nor participation in the so-called 'electronic jamming incident' you have raised."

"We're not going to take any responsibility for that because it really had nothing to do with us."

Hearing this, a mocking smile appeared on the man's face.

The mouth is really hard.

He probably didn't know that his side had found their secret base on a small island.

He probably thought that he summoned him this time because of speculation and bluffing without evidence.

These people always seem to be like this, they will never admit their mistakes until the worst end has happened to them.

——

However, there is no way to show him evidence.

The reason is simple, the income is too low, and even if there is evidence, as long as it is not forced to stop and land on the spot, the other party will still carry it to the end.

That being the case, it might as well just wipe out all the leeway and fight to the end.

Thinking of this, he regained his composure, and then said:

"You've got a good idea of ​​the possible consequences, haven't you?"

Hearing this, the man's heart beat violently.

It has to be said that it is difficult for even him to maintain 100% composure in the face of such a serious threat.

But fortunately, his mood quickly stabilized.

It's okay, the other party has no evidence, and it is impossible to have evidence.

All electronic interference occurs outside the defense zone. Even if the other party takes a photo, one's own side can refuse to admit it.

As long as you don't admit it, it is impossible for the other party to initiate further actions.

That will only get them into a legal and moral dilemma.

These opponents will not be so stupid.

As a result, his mind was settled and his tone became more relaxed.

"Yes, I am aware of the possible consequences."

"But I still want to say, there is nothing wrong with wanting to commit a crime?"

"Sir, if you insist that this matter is related to us, then we hope that you can produce sufficient evidence."

Having said that, he deliberately paused for a moment, then continued:

"The evidence I'm talking about is not the so-called 'photographs' or 'radar records'."

"We all know that can be faked, don't we?"
