East China Sea.
An EF-18 fighter jet was flying at an altitude of 6,000 meters. The electronic pod mounted under the belly of the aircraft was continuously sending interference signals in the direction of the intended radar.
Driver Yota Katsumura stared at the radar screen warily, his right hand never daring to leave the throttle lever.
He has made up his mind that as long as he sees any UFO on the radar screen, he will immediately activate the afterburner and flee in the direction of his own base.
confrontation?
Fight shit.
He knew the nature of his mission very well. In fact, it was just his own plane. The total of four electronic jammers dispatched on this mission were actually nothing more than bait.
The purpose of flying to this airspace is to use the United States' latest ARES electronic jamming system to disrupt China's radar echoes, create the illusion of a UFO invasion, lure them into combat readiness, and turn on other radars, so that the ARES system can collect More intelligence.
Of course, he also knows that after experiencing many similar incidents a few years ago, China's vigilance has also increased, and the probability of them overreacting like before is very low.
However, even so, our actions are not meaningless.
Interference after interference will tie up most of the other party's resources and energy, leaving them no time to take care of affairs far away in Africa.
Therefore, there is only one core of this task:
Don't get caught, don't let them know, it's the island nation that did it.
Even if they are really discovered by the opponent's fighter jets taking off, they can't get too entangled and directly turn around and fly to Kadena. If there are any problems, let China and the United States communicate.
Thinking of this, Katsumura Yota breathed a sigh of relief.
He lowered his head and glanced at his watch. The time had reached 11 a.m., and 20 minutes had passed since they started jamming.
He turned his head subconsciously and said to Kitahara Sosuke, the electronic warfare operator sitting behind him:
"It's almost time, get ready to return."
"receive."
Kitahara Sosuke answered briefly, and then he strengthened the power of the electronic jamming pod and converted it from directional jamming mode to full-band jamming.
This is a smoke bomb during their evacuation phase. After the last interference is over, they will immediately leave the current airspace and evacuate to a safe area as quickly as possible.
A few seconds later, the EF-18 began to turn and the afterburner was turned on. Yota Katsumura looked at the instruments in front of him and synchronized the flight information with Sosuke Kitahara.
"It is 220 nautical miles away from the opponent's territorial waters and has a speed of Mach 1.4. It is expected to leave the pursuit limit in 6 minutes."
"Height 6000, continue climbing."
"Received, the electronic jamming pod has been shut down to identify friendly signals."
"Friendly signal recognition, return."
The speed continued to increase. After more than ten seconds, the EF-18 reached its top speed of Mach 1.6. At this time, Katsumura Yota finally relaxed completely, and the fingers that were holding the joystick tightly finally got a rest. .
He let out a long sigh and said in a tired voice to Kitahara Sosuke behind him:
"It's finally over. Although we are more than a hundred nautical miles away from them, I still feel like we are provoking a monster."
"Its eyes are staring at us, and maybe it will attack us next second."
"As long as we move just a little slower, this mission will probably be a no-go."
After hearing his words, Kitahara Sosuke did not answer immediately.
In fact, why doesn't he worry about his own safety?
But compared to Yota Katsumura, he has less choice.
——
After all, the joystick is not in his hand, so even if he wants to escape, he can't escape.
However, he would naturally not say such words to Katsumura Yota.
After thinking for a moment, he spoke:
"Actually, our strategy is very safe."
"The interference initiation distance is 220 nautical miles, and the opponent's reaction time is at least 2 minutes. At the same time, it takes at least 2 minutes for fighter jets and early warning aircraft to take off."
"It takes at least 2 minutes for the early warning aircraft to detect the enemy - this is the fastest situation."
"The opponent's maximum speed is Mach 2.6, and our maximum speed is Mach 1.6."
"In other words, it will take at least 21 minutes from the time the opponent takes off to discovering us and entering the attack range."
"These 21 minutes are enough for us to fly to safe airspace."
"Don't worry, they can't catch us - isn't this system designed for this purpose?"
"really."
Katsumura Yota nodded in agreement.
This was his last resort.
After all, ARES is the most advanced electronic warfare system in the United States and even the world.
According to the upper management, the technology used in this system has been ahead of the world for at least 20 years.
If it weren't for the fact that the situation was too complicated, Jianlou would not have agreed to expose this system in advance that was supposed to be used after the war started.
After all, exposing existence means exposing weaknesses, which means that countermeasures will come quickly.
Especially under the current circumstances - China's technological development rate is almost unreasonable. Who knows how long it will take them to develop countermeasures?
One day, one month, one year? ——
Even a year is too fast.
This is probably a forced choice.
Thinking of this, he suddenly asked:
"So why don't they just do it themselves and do it through us?"
Kithara Sosuke was stunned for a moment, then replied:
"This is the certificate of submission."
Hearing this answer, Katsumura Yota fell silent.
Indeed, after carrying out this mission, regardless of whether they are identified or not, the island country located in the east will be forced to be bound to the United States.
In this way, the United States directly broke the balance of interests established by China with THAAD.
I have to say, this is indeed a brilliant move.
Yota Katsumura wanted to say something else, but Sosuke Kitahara continued:
"But there's nothing wrong with that."
"ARES is too powerful. As long as it exists, the East China Sea will never be peaceful."
"As long as the East China Sea is unstable, their aircraft carrier will not be able to travel far - and similarly, that powerful destroyer will also be held back."
"Perhaps we will face tremendous pressure in the short term, but as long as we survive this period, we will still be the final winners."
"Makes sense. But what if"
“What if the advantages of ARES no longer exist?”
Kitahara Sosuke immediately fell silent.
He didn't know how to answer this question.
The probability of this happening should be very low, right?
However, he did not know that at this moment, there was a ghostly fighter plane floating in the sky above him.
——
No, that was not the J-22 that took off from the base after being interfered with.
But it was the H-20 that was already performing training missions over the East China Sea.
Two hours later, inside the headquarters.
The man in military uniform stood in front of the sand table with a serious face, and the person connected remotely was Chen Nian in Chengdu.
"So the situation is now very clear. The other party is using a brand-new electronic warfare system. Different from the ALX-99 and SPASM systems we are familiar with, this system is more powerful and has a wider range of effects."
"According to the scanning results of the Kongjing-500, the opponent's electronic jammer launched the attack from at least 200 nautical miles away, and the jamming signal was injected directly from the main lobe of the radar."
"Even the most advanced digital array radar cannot completely eliminate interference from this system."
"The other party's purpose is obvious, which is to launch electronic warfare against us, consume our military resources through non-thermal warfare means, and contain our global strategy."
"The situation is very serious. According to the feedback from 14 institutes, we currently do not have the means to deal with it."
"The only thing we can do is to strengthen maritime combat readiness, ensure the presence of air power, and move away as soon as possible when interference occurs."
"But the cost of doing so is extremely high, and it is more likely to expose the weaknesses of our fourth-generation aircraft. It can even play into the enemy's hands."
"So, what we are going to discuss in today's meeting is how to contain the opponent's electronic warfare offensive in a short period of time at the lowest cost and gain time for 14."
"Let's start speaking freely."
As soon as he finished speaking, someone in the venue raised their hands.
The man nodded, and the latter asked:
"Where did the electronic jammer take off from?"
"According to the intelligence sent back by the H-20, the takeoff location should be Ishigaki Island, but there is no complete air force base established there, only a temporary runway."
"Preliminary judgment is that it should have been built recently."
“Islander or American?”
"Island people."
"Can we directly attack the island and destroy the facilities on the island?"
Hearing this, the man in military uniform shook his head helplessly.
It seems that the previous "exercise operations" against Vietnam did increase the confidence of many people, causing their first reaction to change from "condemn and denounce" to "direct action" when faced with provocations.
But obviously, strategies that are useful for treating monkeys are not necessarily practical here in the island country.
The reason is simple, they all beat dogs, but different dog owners will have different consequences.
"It is impossible to adopt a hot war strategy against them, at least not at this stage."
"Not firing is our bottom line, we can't take any chances."
"Understood."
The questioner sat down again, and then someone else asked:
"Now that we know where the opponent is taking off, can we monitor Ishigaki Island around the clock and issue an early warning immediately if an electronic warfare aircraft is found to be taking off?"
"Pointless."
The man continued to shake his head.
"Even if we can grasp the opponent's take-off information, we cannot organize an effective eviction without radar tracking."
“What about building island radar stations?”
"Then it goes back to the original situation. Even a digital array radar cannot completely offset the opponent's electromagnetic interference."
"Unless the fire control radar is turned on and millimeter wave tracking is performed."
"But in the current situation, if fire control irradiation is carried out at will outside the territorial waters, big trouble will happen."
After hearing this, everyone in the venue fell silent.
In fact, they really can't think of a better way to deal with the current situation.
The island country has submitted its petition, which means that pressure through economic or political channels can no longer have any effect.
However, if you want to use purely technical means, you cannot solve the problem in a short time.
The situation seems to be at an impasse.
At this moment, Chen Nian's voice came from the connected communicator.
"Digital Array Radar Can Fight Jamming."
"The other party is using the ARES electronic jamming system. I know the weaknesses of this system."
For a moment, everyone's eyes were focused on the small speaker.
Their eyes looked as if Chen Nian was sitting there, sitting opposite them.
Everyone's eyes were full of anticipation, quietly waiting for Chen Nian's further explanation.
"The core capability of the ARES system is to use high-performance processors to analyze radar pulse characteristics, apply digital modulation methods, track radar band signals in real time, and inject interference signals directly from the main lobe through simulated echoes."
"Essentially, this technology is also a branch of 'digital array radar' technology, so they are actually using the same technology as us to interfere with us."
"I have to say that Laomei's technical foundation is still there. If it weren't for this incident, I can hardly imagine that they would have such technology."
"I don't know how many backhands they have hidden that we don't know about, and they will be revealed one by one in the future."
After hearing Chen Nian's words, everyone in the conference room couldn't help but be stunned.
While saying "I can't imagine having such technology," I also developed digital array radar technology a few years ago.
Is this looking up to old Americans, or looking down on them?
However, Chen Nian didn't know what everyone was thinking at this time. He just continued:
"In this case, neither using equal countermeasures to develop electronic warfare equipment nor further iterating the radar system will achieve much good results."
"If the time goes too long, we will be tortured to death by them."
"So, the most cost-effective solution is to develop new anti-interference algorithms."
"Currently we are using an anti-mainbeam interference technology based on the blind source separation algorithm (BSS). This technology's performance deteriorates seriously under low signal-to-noise ratio conditions and cannot resist the interference of the ARES system."
"However, we can upgrade it based on the BSS algorithm and use BSS and fractional Fourier transform (FRFT) algorithms."
"First use the classic BSS algorithm to separate the received main-beam interference mixed signal, then perform FRFT transform processing on the separated signal with linear frequency modulation signal characteristics, and filter in the FRFT domain to remove most of the noise energy. Finally, the inverse FRFT transform recovers Target signal.”
"This algorithm can greatly improve the radar peak signal-to-noise ratio. Combined with digital array radar technology, it can greatly reduce the interference of the ARES system."
"In addition, going one step further, we can use neural network learning technology to intervene in the signal analysis process to improve recognition efficiency and help improve recognition accuracy."
"I will submit the plans for these two algorithms as soon as possible."
"For the neural network learning part, I recommend a guy who might know better."
The person Chen Nian mentioned was naturally Wang Jiancheng, but he did not immediately name him at the meeting.
After hearing what he said, the man in military uniform finally relaxed and asked:
"Mr. Chen, how long do you estimate it will take?"
"One day - but that's just the time to update the FRFT algorithm."
"In addition, I would like to make it clear that this is just a temporary measure. We are making progress, and so is the other party."
"Soft technologies such as algorithms are the easiest to be surpassed. If you want to really solve the problem, you must either start with the hardware or directly defeat them."
"The hardware is too late, my suggestion is the latter."
After the words fell, the man in military uniform frowned slightly.
"It is not appropriate for us to use force under the current circumstances. There is really no way around it."
"We will not use force."
Chen Nian's voice paused for a moment.
Then, he continued to speak:
"Judging from the current situation, Laos and the United States only have a relatively strong ARES system, but the radars they deploy in the Asia-Pacific region are products of the previous generation of technology and do not have strong anti-interference capabilities."
"As for island countries, let alone that."
"So, they can interfere with us, but we can't interfere with them?"
"If we don't fight, can't we let them fight themselves?"
"They want to create a huge depression for us, and we can give them a taste of the same!"
