Chang Haonan's idea sounds quite self-liberating at first glance, but if you think about it carefully, it is not outrageous.

Because electromagnetic interference, at least injection and relay electromagnetic interference, as a mode of interference that can only be dealt with after receiving radar waves, there is little that can be done against passive detection methods that do not emit electromagnetic signals themselves.

In fact, choosing the J-7 as a platform is also a way to do it.

The poor maneuverability and large radar reflection area determine that it will become a relatively conspicuous target in itself, and if the other side has an early warning aircraft to command, it is easy to detect and intercept this plane that is wandering away from the battlefield and ready to move in advance.

The power supply of 2*15kw is relatively insufficient, and it will also become a shortcoming in the face of real high-intensity electromagnetic confrontation.

But at present, Huaxia has just begun to localize the Su-27, and as for the stealth aircraft, there is not even a shadow.

There is only one type of heavy tactical platform that can be used.

It's better than Yun 8......

Conversely, however, electromagnetic waves emitted by enemy AWACS aircraft can also be used as a means of passive detection, and if there is an anti-radiation air-to-air missile with a long enough range......

Laughing to death, what an early warning aircraft, Lao Tzu is an early warning aircraft!

In short, there is no one perfect weapon in the world, but a variety of weapons that are not perfect can still produce unexpected effects if they are properly matched.

"In fact, this model also has potential for the detection of low-RCS targets, that is, stealth targets, that is, as Guo Gong just mentioned."

Xu Yang, who had just been quietly listening to Chang Haonan's explanation, also opened his mouth at this time and added:

"However, this requires some more unique techniques, such as the track-before-detection (TBD) algorithm, which uses coarse data that has not been extracted by parameters, or point measurement data processed by parameter extraction algorithms with very low detection thresholds, to directly or indirectly accumulate the target likelihood ratio function, so as to improve the signal-to-noise ratio of passive radar."

"Dr. Chang and I tried several ideas and found that the current iterative-based TBD algorithm can only process one frame of data at a time, and it basically has no operational value in engineering from the perspective of data accumulation speed or computational volume.

Specific to the major of cybernetics and algorithm theory, Xu Yang is not even worse than Chang Haonan after opening the hanging, and the latter's main business is still engaged in aviation after all, so he took on this task as a matter of course.

Anti-stealth is an urgent issue for all countries in the world at present.

Considering that Huaxia does not have the conditions to build such a super-large radar station as the Donhe 2N, it can only make more efforts in terms of four or two thousand pounds.

"Enough, enough."

Guo Lin, who was shocked by the efficiency of Chang Haonan and Xu Yang, looked at the pile of paper on the table filled with dense formulas and charts, and for a while it was hard to imagine what kind of state they were working in the past few days:

"It's enough to be able to do this at this stage......"

For the 14 institutes that originally just wanted to study the seized pod, at most a wave of reverse engineering, this was definitely a surprise.

First of all, a tactical pod with a smaller size and more functions was created, and it was a direct earth-shaking update of passive detection technology and radiation tracing technology.

Although the main completers of these achievements may have to be named after Jinghang University or the Institute of Computing Technology of the Chinese Academy of Sciences, the final implementation of product development and production can only be completed by their electrical technology group.

"Anyway, with this thing, the next time we meet EA6B, we will definitely not repeat the mistakes of 94!"

The engineer who had just used the tactical analogy of a submarine to a passive radar detection also spoke again.

Chang Haonan remembered that his name was Lin Boyuan.

The air situation incident in 1994 was a wound that could hardly be erased for a long time for the entire Huaxia Air Force and the entire electronic technology group.

Generally, it takes a long time for this pain to heal.

But there are exceptions.

For example, now, Chang Haonan spent a week cured.

But at present, it can only be regarded as a symptomatic treatment, if you want to cure the root cause...... It's simple, just give the other party the same lesson in a similar way when you have the opportunity.

Of course, no matter how exquisite the algorithm Chang Haonan and Xu Yang came up with, it still has to be implemented in the equipment and procedures after all.

So after confirming that everyone basically understood what he had just said, the former began to assign tasks in an orderly manner:

"Then we will divide it into three parts and work together to move forward with the project."

"Guo Gong, you take a few people back to Jinling, add two sets of antennas and back-end software on the basis of the 1472 radar equipped with J-8C, so that it has passive detection capabilities, and install it on the aircraft for testing, I will coordinate with the 112 factory, you can directly extract one from the finished product that has not been delivered to them to modify it, which will be faster."

"Okay."

Guo Lin agreed neatly, and then selected four from the other 14 personnel who came over, and then said to Chang Haonan:

"After all, Jinling is the base camp of our 14 institutes, and I can still find other foreign aid after I go back, and the rest will stay here."

"That's fine."

Chang Haonan looked at the staffing in the conference room and found that there was indeed a shortage of people if the soldiers were to be divided into three ways:

"All the remaining comrades here in the 14th Institute, you are responsible for modifying the hardware part of the No. 2 pod according to the plan we set before, and the improvement of the PRI algorithm we proposed this time only needs to rewrite the algorithm software of the pod, and this part of the work can be completed by Researcher Xu."

Xu Yang didn't answer, just nodded slightly.

"In the end, it's me, and I'll go back to my old job during this time."

Chang Haonan deliberately put a bit of joke in his tone to alleviate the overly serious atmosphere in the conference room:

"The J-7 that we are going to use as an electronic warfare platform is a transformation of an old aircraft, and there are a lot of small chores to deal with, and the progress should be much faster with my participation."

"Is there anything else you'd like to ask?"

With the improvement of management ability and experience, Chang Haonan's effectiveness in issuing instructions is gradually improving.

Everyone shook their heads and said no.

"In that case, this model is very important, and it is an important link for our army to seize the right to control the electromagnetic system in a possible future war, and it can be put into service one day earlier, which will play a huge role in the formation of comprehensive combat effectiveness."

According to the usual practice, Chang Haonan made a brief summary and mobilization.

"Electromagnetic power?"

This peculiar and novel expression immediately attracted the attention of many people.

But Chinese has this good, even if you encounter a new word that you have never heard of, you can understand it only by literal meaning.

So it didn't take long for everyone to understand what it meant.

Just like air supremacy and sea supremacy, the so-called electromagnetic supremacy is the ability to control electromagnetic wave signals within the entire battlefield.

In the past, Huaxia was occupied by others in this regard, and there was almost no power to fight back.

But this time, this model, which is tentatively designated as "J-7", will become a symbol of the horn of the counteroffensive!
