"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, and 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, so as to 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 do electronic jammers 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 have indeed increased 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 dealing with monkeys may not be practical here in the island country.

The reason is very 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 cannot take risks."

"Understood."

The questioner sat down again, and then someone asked again:

"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 takes off?"

"Pointless."

The man continued to shake his head.

"Even if we can grasp the opponent's takeoff 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 under the current situation, if you conduct fire control irradiation at will outside the territorial waters, big trouble will happen."

Upon 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 already submitted its petition, which means that pressure through economic or political channels is unlikely to 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 combat 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 also belongs to the branch of 'digital array radar' technology, so they are actually using the same technology as ours to interfere with us."

"I have to say that the technical foundation of Lao America 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.

Does this mean that you look up to the old beauty, or do you look down on it?

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 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, and combined with digital array radar technology, can greatly reduce the interference of the ARES system."

"In addition, to go one step further, we can use neural network learning technology to intervene in the signal analysis process, thereby improving recognition efficiency and assisting in improving recognition accuracy."

"I will submit the plans for these two algorithms as soon as possible."

"For the neural network learning part, I recommend someone who may know more."

The person Chen Nian mentioned was naturally Wang Jiancheng, but he did not immediately name him at the meeting.

After hearing his speech, 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."

"It's too late for the hardware, so 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!"
