The military-industrial scientific research system of the academic master

"Electromagnetic prism..."

Wang Hong asked to reminisce about this name that sounded very powerful.

But because of the lack of literary bacteria, I really didn't recall anything.

It's more like a casual...

So I simply gave up and asked about topics related to my business:

"You just said that it is impossible to deceive for too long... How long can it leave us a window?"

He had seen the hit effect of hypersonic warheads a few years ago, and according to his superiors, the model tested this time was faster and more powerful, although there was no warhead installed.

After hitting the target, it will inevitably leave a very eye-catching trace.

If you want to fully recover, it will take as long as a week. Considering that it is inconvenient to start work during the day, it will basically take half a month to go.

Besides, the frequent activities of large-scale construction machinery will leave many traces that cannot be completely erased.

Even at night, infrared imaging satellites can always capture some abnormalities.

So a more realistic way is to hide it.

But whether to cover a layer of camouflage or build a shed directly depends on how much operating time you can have.

"It's not a problem for about 6-8 hours. If it's longer...it depends on luck."

Chang Haonan raised the telescope in his hand and looked at several staff members who were digging pits and driving piles in the distance.

Of course, there are many kinds of mechanical equipment that can be assisted in completing this type of work, but to minimize the traces of work as much as possible, it still has to be done manually.

After a few seconds of pause, he continued to explain:

"After all, the intelligence agencies in the United States are not ordinary people. After being deceived for a while, they are likely to detect some abnormalities and adjust the characteristic parameters of the synthetic aperture radar... The working principle of electromagnetic prism is actually similar to the deceptive interference of ordinary radars. , so it is highly dependent on the reception and analysis of active signals, and with too many parts that need to be calculated, it is difficult to keep up with the other party's rhythm in real time."

Wang Hong asked his head to lower his head and thought for a moment:

"If it takes 6-8 hours, I'm afraid there is only time to simply block the hit area, and recovery is impossible no matter what."

This sentence made Chang Haonan stunned, and then immediately realized that the other party had misunderstood his meaning:

"There is no need to be completely restored... and there is no need to cover it. Just clean up the main features left after the hit during this period, so that the bullet marks look like they are left by an ordinary ground-based bullet. This way Come on, the other party should make misjudgment on our R\u0026D direction for a long time, or at least wander between the two possibilities."

Wang Hong was shocked:

"So that's the case?"

"It is better to lose it than to block it, not to mention that there are so many actions during this period, and the scope of it is wide..."

Chang Haonan replied:

"Even if there is no problem with the core joints we are directly responsible for, the peripheral projects and personnel will leak some news. In this case, no matter how tight you hide it, it will inevitably be exposed. Instead, it will guide the other party to draw the wrong conclusion they want. It would be better.”

Wang Hongrang first showed a thoughtful expression, but soon became puzzled:

"But I remember... It seems that about half a year ago, the United States hyped up our hypersonic weapon threat and threatened to impose sanctions on our relevant organizations and individuals. Will anyone take this? Something is related to the bounce traces left by the shooting range, and to infer the real situation? ”

Chang Haonan laughed in silence and immediately asked:

"Then you see, half a year has passed, have they imposed sanctions?"

Wang Hongrang shook his head very simply and blurted out:

"How can I know this? I'm not a key person..."

At this point, it ended abruptly.

He looked up at Chang Haonan not far away in front of him—

Obviously, if you want to say "relevant individuals", then there is probably no one more relevant than the one in front of you.

So I changed my words immediately:

"I think it should be...no?"

"That's it."

Chang Haonan explained:

"The psychology of Americans is actually much simpler than that of Europeans. I have studied a little bit... They hyped up our hypersonic weapon threat just to make HTV2, the gliding superb similar to the Xuanniao principle, successfully obtain research and development funds. That's it."

"But the reason why we dare to hype this is because deep down, they don't think we can really develop hypersonic aircraft... or at least it's impossible before them."

Wang Hong's confusion on his face did not fade much, and he obviously didn't understand the cause and effect relationship here.

"I don't know if you've heard of a joke."

Chang Haonan simply changed his approach:

"It was said that a reporter asked the Pentagon's spokesperson why he had to spend so much resources to send troops to the Mesopotamian River Basin. The other party said that it was because he suspected that there were weapons of mass destruction there. The reporter asked again, why didn't he send troops to Moscow directly? The man had to answer, because the Russians really had weapons of mass destruction…”

Wang Hong refused to hold back after hearing this and burst into laughter.

A happy air suddenly filled the Gobi Desert...

...

Of course, jokes and joy are short-lived.

Even with the successful experience of the past double-cone verification bomb and the large amount of data provided by the JF14 ultra-high-speed wind tunnel, the superb test shot of the gliding type is still a major event that requires careful preparation and seriousness.

And, according to the general logic of the development of military science, after having a spear, one will naturally start to consider the issue of shields.

In fact, as early as 2005, when Chang Haonan used the Dongfeng 3 missile to test the feasibility of the hypersonic reentry of the double-cone warhead, the ground-to-air missile force had confirmed that the conventional long-range warning radar could only barely capture some intermittent signals and could not provide a long enough warning preparation time.

The fire control radar designed for aerodynamic targets cannot stably track targets in hypersonic flight state, let alone launch missiles for interception.

The verification missile launched by Tu-160 later basically verified this conclusion.

When monitoring the first flight of X51A, a strategy was also used to outsmart it through a multi-base radar solution.

The speed of the "Xuanniao" hypersonic verification platform is faster, almost twice that of the previous three. It can already generate a plasma absorption layer of a certain intensity around the flying body, and it uses a highly flexible gliding trajectory.

Not to mention interception, even early warning of incoming missiles is difficult to achieve.

Twenty years ago, this situation might have been acceptable.

After all, during the Cold War, the main threats to the two superpowers came from each other, and China only needed to have a passing level of strategic deterrence to maintain basic security.

But now, China has firmly sat in the position of the second largest country, and still maintains an outrageous growth level of about double digits.

Anyone with a discerning eye can see that if this trend continues, it will sooner or later become the main opponent across the ocean.

In this case, if the party that is already at a disadvantage lets the opponent make the first move, it will only become more passive.

You can only abandon your fantasy and make preparations early.

Therefore, the construction of a new set of strategic early warning and even missile defense systems was put on the agenda almost at the same time as the "Xuanniao" entered the formal research and development.

And the first action related to it is the Maodao radar station located in the west of GS Province-

Of course, it does not mean that the Electronic Technology Group has found a way to deal with the threat of hypersonic weapons in just a few months.

But before that, they need to first have a clearer understanding of the capabilities of both the offensive and defensive sides.

According to the plan, the Air Force will rebuild the Maodao radar station, install an L-band phased array radar using the latest technology on the base prepared for the 7010 radar, and track and monitor the test launch of the hypersonic aircraft without prior preparation.

Then, based on the data of this test, consider whether to upgrade the existing model or develop a new strategic early warning radar.

As for the Maodao radar station itself, it can continue to shine as a training and tactical research facility.

In fact, the reason why the first test launch of the "Xuanniao" was determined in the second quarter is also partly because it is waiting for the radar to be completely completed...
