Meanwhile, Chengdu.
In order to solve the problem as quickly as possible, Chen Nian had to temporarily put aside his 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 CHL-906, the current electronic warfare equipment in 14 institutes, and will leapfrog to the most advanced CHL-1106 equipment in 15 years.
For him, this is not difficult at all. Even without the help of the system, he can slowly figure out the technical documentation of CHL-1106 in a month or two by relying solely on the knowledge and technology he has accumulated over a long period of time. .
From a certain perspective, it is not cost-effective to use source points to analyze CHL-1106 when there is a system.
But what Chen Nian needs to consider now is not cost-effectiveness or cost-effectiveness, but how to solve the current predicament as quickly as possible.
Therefore, without any hesitation, he directly obtained the CHL-1106 document through the system and output it on paper in the shortest possible time.
Experts from the 14th Institute had already flown to Chengdu to wait. After receiving Chen Nian's technology, they started discussions without stopping.
In the conference room, Liu Yongtan wore reading glasses and habitually turned over the materials in front of him with his hands stained with saliva. He whispered while reading:
". With phased array radar and digital array technology, the composition of this antenna is not much different from the current CHL-906. There are also gallium nitride components. Basically, from a purely hardware perspective, there is nothing big. question."
"The current problems mainly lie in two aspects. The first is the artificial intelligence and machine learning algorithms mentioned."
"We don't have any experience in this area, and we don't have anything to refer to."
"Even if the code is written, problems will continue to occur during the subsequent training process."
Liu Yongtan, as a scientist of the older generation, certainly cannot be a "veteran" who has not changed his ways as some people in society think.
On the contrary, due to his rich experience and 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 methods of the other party's radars and their pulse characteristics is many times faster than manual analysis.
If it can be realized, the current electronic countermeasures technology in the world will inevitably take a big step forward.
Of course, the only problem, as he said, is that no one has tried this technology before.
In the past, I had to cross the river by feeling for the eagle sauce, but this time I could only cross the river by feeling for the stones.
It was very difficult to reach the predetermined level in a short period of time, and he lacked confidence.
After hearing his words, Chen Nian nodded and said:
"This problem is indeed difficult to solve, but it doesn't matter. We don't have to reach a completely perfect level at the beginning. We can practice while using 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 to achieve our tactical purposes. "
"To put it bluntly, what we have to do is to first whiten the opponent's radar, and then put bright spots on the whitened radar, making them think that those bright spots are burned-through flying objects."
"By doing this, our goal will be basically achieved."
What Chen Nian refers to as "radar burn-through" actually refers to the situation where "because the flying object is too close to the radar, the intensity of the radar echo signal exceeds the intensity of the electronic interference signal, resulting in the flying object still being discovered 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.
During the jamming process, ground radar is also simultaneously 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 is reflected from the aircraft back to the radar and travels a distance A. In other words, the echo signal travels a distance of 2A.
But the jamming signal sent by the jammer only goes as far as the radar distance A.
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 only applies to the jammer itself.
In actual combat, the purpose of interference is to allow fighter jets to penetrate the defense.
Once the fighter jet echo signal is very strong, it may exceed the interference signal power provided by interference outside the defense zone and be recognized by ground radar.
This is called "burn through."
With the help of this mechanism, the jammer can create the illusion of "burning through after jamming" and complete the trick 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 maintain that high interference power."
"Based on the current combat platform, the two fourth-generation aircraft must be eliminated first and cannot be used."
"J-10? The range is too short and the avionics are too weak to support the needs of CHL-1106."
"Yun-8F is currently very difficult to modify and cannot meet the time requirements."
"Judging from the current situation, the most feasible solution is even to modify the H-20."
"No need."
Chen Nian looked at Liu Yongtan in surprise and asked:
"Mr. Liu, have you forgotten something?"
"It is true that most current fighters cannot meet the modification requirements of CHL-1106, but drones can."
"Don't we have Rainbow-9? It's totally fine to put CHL-1106 directly on this platform, right?"
Liu Yongtan shook his head and replied:
"No, our current satellite communication system is not perfect enough, and the command efficiency is actually not high enough. It is too difficult for a drone to complete complex jamming tasks."
"Not to mention anything else, remote command alone is already very difficult to achieve."
"After all, as long as 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 need for remote control."
Chen Nian immediately shook his head.
"Just fly with the drone and let the J-20 command the CH-9."
"The Yujing project has been in progress for so long, and it has now been updated to the fourth generation."
"I think we can take advantage of this opportunity to try out our 'Loyal Wingman' plan."
On the other side, NPU.
Wang Jiancheng is still tinkering with 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 entrusted by the so-called Chengfei to develop an exoskeleton for the government that could adapt to low-intensity security maintenance work.
At the beginning, he thought that this type of exoskeleton was mainly used for urban police use, but as development needs were raised one by one, he gradually came back to his senses.
There's no way this thing is for police use.
It should be said that it will be used in "cold weapon conflict events" under certain specific circumstances.
Where could such an event occur?
The answer goes without saying, he can understand it.
Therefore, after deducing this information, his enthusiasm increased.
This is the first time he has participated in equipment that may be directly used in "actual combat"!
There must be no mistakes and every detail must be done to the best of its ability.
For two months, he spent every day in the laboratory, working hard to optimize the product at hand.
Although Qiu 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 every now and then.
This gave Wang Jiancheng a lot of help. Without Qiu Mai, his work efficiency might 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 still maintain pure technical cooperation.
However, the two of them didn't feel embarrassed about this at all. It seemed that they had already learned how to interact with people according to workplace standards even before they entered the workplace.
On this day, Wang Jiancheng entered the laboratory as usual and prepared to start his day's debugging work.
But before he could complete his first experimental project, the confidential mobile phone specially configured for him by Chengfei rang.
Wang Jiancheng thought he was here to promote progress. He hurriedly opened his experimental records and was about to report according to the records, but the news that came over the phone made him freeze in place.
Not news about the exoskeleton project.
It is a project that can be said to be new, but also old.
Neural network machine learning project.
The "leader" on the other end of the phone made two requests to him.
The first requirement is to continue to improve the Yujing 04 flight control system 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 interference signals at specific frequencies and wavelengths.
Regarding the first request, Wang Jiancheng was not surprised - in fact, he had already completed most of the work, and only the finishing touches were left.
But with the second request, he was in a bit of a dilemma.
"Leader, identifying radar interference signals is not that simple - maybe machine learning can indeed help to a certain extent, but the problem is that it is impossible to achieve the expected results by relying on artificial intelligence training alone."
"We need rich data and more accurate probability algorithms to help improve the success rate. To be honest, I'm not very good at this."
When Wang Jiancheng said "very bad", he did not mean that he was a scumbag in the field of mathematics. In fact, his mathematics was much better than that of ordinary college students.
What he really means is that his current level is not enough to handle the requirements of the task.
In his view, in order to meet the task requirements, at least in terms of 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.
This is obviously not the level he is at, nor is it a 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 calmly:
"Mission 2 is not given to you alone. We have formed a team to tackle this task."
“In the team, you only need to be responsible for the machine learning part.”
"As for the field of mathematics, we will recruit additional relevant professionals into the group."
"Professional? What level of professional?"
Wang Jiancheng asked subconsciously.
"You don't have 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 was instantly relieved.
If the other party can say this, it means that he must be fully prepared.
In that case, there is no need to worry.
Don't think so much, just play your role.
So, he immediately replied:
"I understand the leader, and I promise to complete the task!"
"Okay, work hard. After completing this mission, your superiors will give you a special reward."
"Special reward?"
Wang Jiancheng murmured, but the man opposite him ignored him and hung up the phone directly.
He looked at the phone screen in confusion, and couldn't help but think to himself:
A special reward that I can’t say, so what exactly is it?
Meanwhile, somewhere.
the man asked.
"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, you will be responsible for all subsequent consequences."
The man opposite had a calm expression. He knew that at this moment, he couldn't show any weakness.
Otherwise, if the other party really catches the flaw, everything will become impossible to end.
So, he opened his mouth and said:
"Yes."
"Everything I just said is a true statement based on facts."
"I must reiterate again that we are neither aware of nor involved in the so-called 'electronic interference incident' raised by you."
"We're not going to take any responsibility for that because it really has nothing to do with us."
Hearing this, the man couldn't help but reveal a mocking smile.
What a tough mouth.
He probably doesn't know yet that he has found their secret base on a small island.
He probably thought that he summoned him this time out of speculation and bluffing without evidence.
It seems that these people have always been like this. They will never admit their mistakes until the most tragic ending befalls them.
——
However, he had no way to show him evidence.
The reason is simple, the return is too low, and even if there is evidence, as long as it is not forced to stop and land on the spot, the opponent will still fight to the end.
In this case, it would be better to just wipe out all the room and fight to the end.
Thinking of this, he regained his composure and then said:
"You're aware of the possible consequences, right?"
Hearing this, the man's heart couldn't help but beat violently.
It has to be said that when facing such a serious threat, even he would find it difficult to remain 100% calm.
But fortunately, his mood quickly stabilized.
It's okay, the other party has no evidence and cannot possibly have evidence.
All electronic interference occurs outside the defense zone. Even if the other party takes a photo, you can refuse to acknowledge it.
As long as they don't admit it, it's impossible for the other party to initiate further actions.
That will only put them into legal and moral dilemmas.
These opponents wouldn't be that stupid.
As a result, he calmed down and his tone became relaxed.
"Yes, I am aware of the possible consequences."
"But I still have to say, why bother to accuse someone?"
"Sir, if you insist that this matter is related to us, then we hope that you can provide sufficient evidence."
Having said this, he deliberately paused for a moment, and 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?"
