The military-industrial scientific research system of the academic master

After hearing the conclusion given by the other party, Guo Lin showed a slightly shocked expression.

This time it was definitely not performed.

He originally wanted to make Liao Yongcai feel a little involved so that he could work together in the future, but helping was secondary.

As a result, others really made a big one.

"Someone interferes..."

A few seconds later, Guo Lin, who came to his senses, subconsciously looked at the map of Longyuan Province posted on the wall of the control room:

"But there is a Gobi desert around here, and it's still inland?"

For him, phase conjugated interference cannot be regarded as a new term.

This technology can omit complex encoding and identification processes and directly generate quasi-real-time interference pulse sequences, so that the power density when the interference pulse sequence returns to the receiver is large enough to disrupt the normal decoding process of the radar system.

But no matter how much you omit it, you will eventually need a considerable equipment.

And because it is still a forwarding interference in nature, this device must be placed where it can receive the interfered target signal.

It is usually some kind of camouflaged fixture, or an airplane.

But the former does not meet the surrounding environmental conditions at all.

As for the second possibility...

It would be a bit likely to say that a stealth plane had come in from the west ten years ago.

Now that even F22 can be caught over the East China Sea, it is obviously unnecessary to consider this possibility.

The young engineer beside him quickly came up with new ideas:

"Is it possible to be reflected by ionosphere..."

As a result, he was interrupted by Guo Lin shaking his head:

"Phase conjugation interference has certain requirements for directional accuracy. It was originally used in lasers, which has only gradually expanded in other fields in recent years... The scattering effect of the ionosphere is too great, do you think of those superhorizon radars? The detection capability and error are calculated in units of hundreds of kilometers, and it is barely enough to use it for communication. It is not realistic to achieve accurate interference."

"Then...has someone penetrated nearby?"

Another person made the assumption, but it was also quickly denied.

Looking at the scene in front of him, Liao Yongcai showed a proud smile.

The ability level of the younger generation of technicians is unquestionable, but people who grew up after the 1980s are usually inexperienced and lack some sensitivity to imaginary enemies.

This means that older people like him still have the energy to play, and they will not be completely eliminated.

“In my experience, it’s more likely from a satellite.”

Liao Yongcai spoke to end the discussion:

"In 1983, when I was in service at Xuanhua Radar Station, I encountered a similar situation..."

Like all those who have grown older, he likes to tell his younger generations about his youth.

But he also knew that it would easily make people feel bored if they were chanting every day regardless of the situation.

And the occasion in front of me is the time to perform.

Sure enough, including Guo Lin, the dozen people in the entire control room listened very seriously, and no one interrupted.

The so-called Xuanhua radar station is the external statement of the 7010 radar back then.

Liao Yongcai served there for a period of time when he was young. The original plan was to let him, as a two-way backbone of technology and management, come to Maodao to pull up the second strategic early warning radar regiment.

But the sudden policy changes have left everything missing.

No one could have thought that more than twenty years later, the experience he accumulated in his last era would come in handy one day.

After listening to Liao Yongcai's explanation, Guo Lin temporarily agreed with the other party's statement, but was still a little confused:

"But if there is a satellite specifically targeting us, will the interference intensity appear to be a bit..."

He glanced at the phase noise spectrum of Array 3 again.

"Some are too weak?"

Liao Yongcai followed the subsequent part.

"Yes... If our radar had not been completed and was in the debugging state, then such interference would have been filtered out by the system as a clutter."

Guo Lin still frowned;

"And in fact, even if the interference source cannot be found in the end and continues to be treated as natural background noise, it will be at most three or four days to perform several rounds of coherence detection and iterative calibration. It seems that it is not worth such a big fight. ”

But Liao Yongcai shook his head:

"Phase conjugation interference is definitely released intentionally, but it may not be specifically targeted at us, nor can it be ruled out that it is a test or test... Of course, this is not the part I can analyze, and it needs to be left to more professionals to judge. ”

Even he himself had to admit that long-term employment in such a closed radar station has indeed greatly affected his ability to obtain new information.

The control room fell into silence again.

Only the buzzing background sound and the sound of the electronic devices or the sound of the sound.

"Mr. Guo, do you have to report this?"

The young engineer who first brought the log files asked.

Before, they had always judged that it was natural background interference, which was a regular part of the radar debugging process. Naturally, the technical team began to try to solve it in one go.

But if you follow Liao Yongcai's speculation, it involves the issue of overseas forces.

Even if there is no difference in the specific solution, the superiors must know that this is the case.

"Yes, we have to report it."

Guo Lin nodded:

"You write a report as soon as possible and deliver it to the group headquarters, Academician Chang and others."

The decision to build a national early warning and missile defense system itself comes from the highest decision-making level and is completely independent of any other project. The military even has plans to establish a new military or service to be responsible for these strategic support tasks.

But this radar is only a pre-task in the pre-task. In order to facilitate cooperation with hypersonic weapons as the "spear", it is included in the same execution plan in management.

"Then let's follow up..."

"First follow the standard procedures, at least for the moment, this intensity of interference will not make the debugging work impossible."

Guo Lin said as he unbuttoned the top button of the work clothes to make his breathing smoother:

"But this is a bit weird... Remember to save the running logs for the past few days, and don't be afraid of delaying the hours, leave a few more backup points, so that even if there are any changes in the future, it will be convenient to make adjustments. …”

...

Due to the delay problem caused by poor communication, Chang Haonan did not receive a report from the Maodao radar station from the correspondent until he returned to the camp of the Mass Effect Range that night.

"Academician Chang and General Manager Guo Lin and Guo personally issued a situation report, saying that their radar debugging process was disturbed and it is expected that it may delay 3-4 days."

When he just heard that "the radar debugging process was interfered with", he thought it was caused by his side for a moment.

But this idea was immediately thrown behind.

Their work has been basically in a silent state so far. Only after each group of font-shaped antenna array is arranged will a startup test be conducted. However, it is only a set of standard signals, which cannot affect the radar hundreds of kilometers away. equipment.

If you take a step back, even if it can have an impact, the test process will only last for a moment and will not be repeated, and will definitely be filtered out directly.

Thinking of this, Chang Haonan felt relieved and took the message from the other party and started reading it.

"The side lobe inhibition rate decreases..."

"Coherence detection is abnormal, and regular depressions are formed in the 1.14GHz frequency band..."

"Suspectedly the interference signal comes from the satellite..."

He subconsciously raised his head and looked at the night sky outside the window.

This place is deserted within a radius of hundreds of kilometers and has not been subjected to much atmosphere and optical pollution from human activities. Therefore, when the weather is sunny, you can only see the dazzling galaxy like in the photos with your naked eyes.

It’s just that there are frequent sandstorms recently, so there is only a gray area that comes to your eyes.

"Xiao Wu."

He came back to the correspondent again:

"Send the abnormal time of the radar signal to the Beijing Aerospace Measurement and Control Center in another name, so that they can provide a copy of the intercorrelation detection between these times and satellite orbits as soon as possible. I will write to you the specific satellite list later."

"yes!"

After watching the other party return to the small room next to him, Wang Hongrang spoke in shock:

"Academician Chang, you are preparing..."

He has worked in the Second Artillery Force for half his life and does not understand radar technology very much, but at least he has learned some basic circuit theories and has seen the guys in the air defense force.

Now someone just looked at the text description in the report and started to assign tasks so confidently, which really challenged his worldview.

"I may have to go to Maodao radar station tomorrow. Director Wang, just continue to do your homework according to today's new plan..."
