At the same time, Chengdu.

In order to solve the problem as quickly as possible, Chen Nian had to temporarily put aside the preparations for metallic 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 the 14 active electronic warfare equipment CHL-906, spanning to the most advanced CHL-15 equipment in 1106 years.

For him, there is no difficulty in this, and even without the help of the system, relying on the knowledge and technology accumulated over a long period of time, it will take a month or two to slowly find out the technical documentation of CHL-1106.

From a certain point of view, it is not so cost-effective to use the source point to parse CHL-1106 in a systematic situation.

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

So, without any hesitation, he got the CHL-1106 document directly through the system and output it to paper in the shortest possible time.

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

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

Thanks to phased array radar and digital array technology, the composition of this set of antennas is not much different from the current CHL-906, and gallium nitride components are also available, basically, purely from the hardware aspect, there is no big problem."

"The problem now is mainly in two aspects, the first 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 objects to refer to."

"Even if the code is written, there will be continuous problems in the subsequent training process."

As a scientist of the older generation, Liu Yongtan certainly cannot be an "old qualification" that eats the old as some people in society think.

On the contrary, because of his experience and high IQ, he is much more sensitive to new technologies than many young academics.

So, when neural network machine learning algorithms first appeared, he was already aware of the importance of this technology in electronic countermeasures.

With the help of the power of the machine, it is many times faster to analyze the working mode of the opponent's radar and analyze their pulse characteristics 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, is that this technology has not been tried by any one before this.

In the past, I used to cross the river by touching the eagle sauce, but this time I could only cross the river by feeling the stones.

It was very difficult to reach the predetermined level in a short period of time, and his confidence was low.

Hearing his words, Chen Nian nodded and said:

"It's really hard to solve this problem, but it doesn't matter, we don't have to reach a completely perfect level at the beginning, we can practice as we use it, and slowly improve."

"The core of this system is to use high-power antennas to directly cover the opponent's echo 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 off the other party's radar, and then point out the bright spots on the white radar, so that they think those bright spots are flying objects that have been burned through."

"By doing that, we will basically achieve our goal."

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

The principle is simple.

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

In the process of performing jamming, ground-based radars are 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 the distance A, and then reflects back to the radar from the aircraft and travels the distance A, that is, the echo signal travels a distance of 2A.

However, the jamming signal emitted by the jammer only traveled to the distance A of the radar.

Although the distance is only twice as long, in reality, this ordinary mathematical formula has a huge impact.

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

However, this situation is only for the jammer itself.

In actual combat, the purpose of jamming is to allow fighters to break through.

And once the fighter echo signal will be strong, it may exceed the interference signal power provided by the interference outside the defense zone, which will be recognized by ground-based radar.

This is called "burn-through".

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

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

"But here's the problem: we can't sustain that much interference power."

"In terms of the current combat platform, the two fourth-generation aircraft must first be eliminated and cannot be used."

“J-10？ The range was too short and the avionics were too weak to support the needs of the CHL-1106. ”

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

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

"No, I don't."

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 requirements for the modification of CHL-1106, but the UAV can."

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

Liu Yongtan shook his head and replied:

"It's not good, at present, our satellite communication system is not perfect enough, the command efficiency is actually not high enough, and it is too difficult to let a drone complete complex jamming tasks."

"If nothing else, it's already difficult to achieve remote command alone."

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

"No remote control."

Chen Nian immediately shook his head.

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

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

"I think it's time to try out our 'Loyal Wingman' program."

On the other side, Western University of Technology.

Wang Jiancheng is still tossing his mechanical exoskeleton equipment, and it is still the "combat exoskeleton" he dreams of.

Of course, this time he was not out of pure "interest", but was commissioned by the so-called Cheng Fei 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.

This thing can't be a police thing.

It should be said that it will be used in a certain environment for "cold weapon conflict events".

Where will there be such an event?

Needless to say, he could understand the answer.

So, after deducing this information, his enthusiasm grew.

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

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

For two months, he spent every day in the lab, working hard to optimize the products at hand.

Although Qiao Mai had already said that she would not invest too much in this project, she would still give Wang Jiancheng some suggestions and technical ideas every once in a while.

This has been of great help to Wang Jiancheng, and if it weren't for Qiao Mai, his work efficiency might have been reduced by at least 20 percent.

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

They still don't like each other, and they still maintain pure technical cooperation.

However, the two are not embarrassed by this at all, and it seems that they have learned how to interact with people according to the standards of the workplace before they have entered the workplace.

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

But before he could complete the first experimental project, Cheng Fei's confidential mobile phone specially configured for him rang.

Wang Jiancheng thought that he was here to promote progress, he hurriedly opened his experimental record, and was about to report according to the record, but the news on the phone made him stunned.

Not a message for an exoskeleton project.

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

Neural Networks 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 Yujing 04 flight control system and reach the available 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 at 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 little that remained was just the finishing touches.

But the second request, he was a little embarrassed.

"Leader, it's not that simple to identify radar jamming signals-—— maybe machine learning can really help, but the problem is that AI training alone can't achieve the desired effect."

"We need a lot of data and more accurate probabilistic algorithms to help improve the success rate, and to be honest, I'm not good at that."

Wang Jiancheng said "very bad", not that he is a scumbag in the field of mathematics, in fact, his mathematics has surpassed the average college student by too much.

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

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

It's obviously not his level, and it's not what he's going to be able to do anytime soon.

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

He just said flatly:

"Mission 2 is not for you alone, we have formed a team to tackle this task."

"In a team, you just have to be responsible for the machine learning part."

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

"Professionals? What level of professional? ”

Wang Jiancheng subconsciously asked.

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

The highest level in the country!

Wang Jiancheng instantly relieved his heart.

If the other party can say such things, it means that the preparation must be sufficient.

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

Don't think about it so much, just play your part.

So he immediately replied:

"Understand the leader, promise to complete the task!"

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

"A special bonus?"

Wang Jiancheng muttered, but the man opposite ignored it and hung up the phone directly.

He looked at the phone screen suspiciously, and couldn't help but think in his heart:

Can't say a special reward, so what exactly is it

At the same time, somewhere.

The man asked.

"So, you still refuse to admit that you were involved in the last electronic jamming incident? I must solemnly inform you that if you continue to refuse to communicate, then you will bear all the consequences caused by the follow-up. ”

The man opposite had a calm expression, and he knew that the more he was at such a moment, the more he could not show the slightest weakness.

Otherwise, if you are really caught by the other party, everything will become unfinishable.

So, he spoke:

"Yes."

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

"I must reiterate once again that we are neither aware of nor involved in the so-called 'electronic jamming incident' that you have raised."

"We're not going to take any responsibility for that, because that's really not about us."

Hearing this, the man's face couldn't help but show a mocking smile.

It's a hard mouth.

Little did he know that he had found their secret base on a small island.

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

These people seem to have always been, and they will never admit their mistakes until the worst end befalls them.

——

However, there was no way to show him the evidence.

The reason is very simple, the benefits are too low, and even if there is evidence, as long as it is not forced to stop and make a forced landing on the spot, the other party will still carry it to the end.

Since this is the case, it is better to directly erase all the leeway and fight to the end.

Thinking of this, he regrouped his expression, and then spoke:

"You're already clear about the possible consequences, right?"

Hearing this, the man's heart couldn't help but skip a beat.

I have to say that in the face of such a serious threat, even he is difficult to maintain 100% composure.

But fortunately, his mood quickly stabilized.

It's okay, the other party has no evidence, and there can't be evidence.

All electronic interference occurs outside the defense zone, and even if the other party takes a photo, the other side can refuse to admit it.

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

That would only put them in a legal and moral dilemma.

These opponents, they won't be so stupid.

So, his mind was settled, and his tone became relaxed.

"Yes, I know the possible consequences."

"But I still have to say, what is the trouble of wanting to add sin?"

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

At this point, he deliberately paused for a moment, and then continued:

"The evidence I'm talking about is not a so-called 'photograph' or a 'radar record.'"

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