The military-industrial scientific research system of the academic master

At the same time.

Hundreds of kilometers away.

The spring breeze of the Qilian Mountains, carrying fine sand and gravel, hit the slightly mottled cement exterior wall of the Maodao Radar Station.

Station Director Liao Yongcai sat on an observation platform, holding a somewhat worn and yellowed notebook in his hand.

There was an old photo in the notebook. Although it was not very clear, it was still possible to see that it was a half-buried building three kilometers away, like a weathered steel skeleton.

That was the 7010 Radar Control Center, which started construction in 1974 but was only about 60% completed and never put into use.

On the hillside slightly away from the camera, a huge cement base outlined a jagged silhouette in the afternoon sun.

This was taken as a commemorative photo when he first came to this radar station-

The functional parts of the radar station are all in the new camp behind him, so these wreckages from the last century are listed as "memorial areas" and are not strictly confidential.

In the following twenty years, the mobile early warning radar that replaced the 7010 radar was replaced by the earliest parabolic antenna, the Cassegrain antenna, and then by the current planar phased array antenna.

Beyond the wall, time seemed to be frozen by the wind and sand, and no obvious changes occurred.

Liao Yongcai had thought more than once that the radar station he was responsible for would never take on the original mission again.

The indicators of the new radar are first-class, but after all, it is only a model used for cooperation with the air force ground-to-air missile force. The core function is to play a tactical role and protect the few large cities in Qingtang and Longyuan areas.

It is completely different from the strategic value that the 7010 radar was expected to play.

However, in just the past few months, everything has changed dramatically.

The memorial area, which was originally planned to be converted into a tourist attraction, was blocked again, and the transport trucks that used to come only 1-2 times a week became frequent visitors every night.

In addition to the usual basic supplies such as food and fuel, the remaining space is filled with various equipment and electronic components.

Of course, there are engineers.

Thanks to the early development time of the 7010 radar, a very large space is left behind the antenna to accommodate various signal processing and command communication equipment at that time.

For the new models of the 21st century, it is more than enough.

It also saves the trouble of major construction.

Until the installation of the antenna recently, some large mechanical equipment has been brought in to cut and replace the old reinforced concrete base due to lack of maintenance.

Regarding the ultimate purpose of this big move, Liao Yongcai currently only knows that it is related to the upcoming hypersonic weapon test.

And his subordinates were told that the radar station will add a track measurement and control department to contribute to the development of the aerospace industry.

Considering that the 110-type ultra-long-range single-pulse tracking radar located in Yunnan Province was indeed converted to civilian use a few years ago, this statement is somewhat credible.

"Director Liao, the joint test data is out."

Just when Liao Yongcai was feeling alone, a voice suddenly came from below.

He turned his head slightly and found that the person who came was Guo Lin, the chief radar designer of the Electronic Technology Group.

The latter was climbing up the platform along the maintenance ladder at this time:

"The electromagnetic background around here is very different from that in Jinling. Our operators have not been able to adjust the electronic scanning antenna to the ideal state. You may need to use your experience."

Compared with specific mechanical equipment, electromagnetic waves and digital signals are invisible and intangible, and the working status of the equipment can only be inferred through some parameters.

And this process is inevitably affected by the external environment.

Especially in the early debugging process, due to the lack of zero point, often a small deviation can bring very outrageous result jumps.

So, it is no wonder that many electronic engineers will believe in some metaphysics later.

For example, something like the joy of the machine soul.

"Okay, let's go."

As an old technician, this feeling of being needed makes Liao Yongcai very satisfied, and the whole person is instantly full of energy.

The two of them returned to the ground quickly, then jumped into a jeep and rushed towards the radar control center in the distance.

…

Even if there was more space, it was impossible to set up a new control center in the underground building reserved for one radar.

Therefore, most of the equipment was updated on the basis of the original one.

Due to the tight time, many traces of the past were left.

For example, the metal pipes sleeping at the bottom of the deep well.

It was originally laid to protect the huge data transmission line, but now it is optical fiber transmission, so the entire inspection well is useless.

Liao Yongcai was worried about accidents when walking and passing, and he mentioned several times that he wanted to fill it up, but he never freed up manpower.

"Mr. Guo, Director Liao."

Seeing the two people walk out of the elevator, a young engineer walked up quickly, holding a stack of documents with the residual heat of the printer in his arms:

"The work log of the trial run just now has been sorted out, please take a look."

Guo Lin did not move, probably because he had seen it on the computer before, but just gestured to hand the file directly to Liao Yongcai.

When the latter received it, he noticed that there was a square piece of gauze on the other party's wrist, and judging from the edge, it seemed to be a mark of burns caused by high-energy microwaves.

This made his shoulders feel a little tingling.

There was also an almost identical scar there, which was left by him at the Xuanhua radar station when he was young.

"I'll take a look."

Liao Yongcai shook his head gently, threw away his distracting thoughts, and sat at a table and lowered his head to read.

Guo Lin quietly came to the other side of the control center, waiting for the former to come to a conclusion.

In fact, if he is given plenty of time, the problem can definitely be solved in multiple iterations.

The reason why Liao Yongcai was specially invited here is that on the one hand, the work can be completed faster with experience, and on the other hand, it also provides this old senior with some sense of participation.

The installation and debugging of the new radar, including the subsequent testing process, was completed by the Institutes 14 and 38 of the Electrical Engineering Department, and the Maodao radar station was almost completely excluded.

Except for Liao Yongcai and political commissar Zheng Tianyu, the rest of the personnel were not even fully aware of the information.

Obeying orders is obedient, but there is also some emotion.

Liao Yongcai's performance did not disappoint Guo Lin.

About an hour later, just when many people were almost forgetting that there was still someone sitting in the corner, he finally spoke again.

"Engineer Guo, you know, equipment debugging is a big deal, and I hope to participate in the work on the spot."

Guo Lin looked at Liao Yongcai's confident expression and hesitated for a moment:

"good."

...

Under the seemingly silent sky, current and electromagnetic waves echoed again in this Gobi desert.

In the control center, Liao Yongcai's fingers were hanging above the red buttons on the console, and the blue light from the LCD screen casts a fine shadow in the wrinkles at the corners of his eyes.

He repeated this action for nearly 30 years, from the mechanical joystick of the 7010 radar to the interface that is no different from the home PC, and consists of a keyboard and mouse. The cold touch of metal seems to remain in the fingertips.

"It looks like...is the phase noise spectrum of Array 3 has a 0.5Hz offset."

Liao Yongcai's voice mixed with the buzzing sounds in the computer room, staring at the three-dimensional beam map on the display screen.

"Director Liao, do you want to run the self-test procedure again?"

Behind him, the engineer who had just handed over the information asked.

"No, I just want to see what went wrong."

Liao Yongcai replied in a deep voice:

"Calling out the phase noise spectrum of array 3."

The beating curves on the home screen reminded him of the rainy night in 1983.

Xiao Liao, who was still a technician at the time, followed the old director to climb onto the radar antenna and wrapped a spectrum analyzer in a military raincoat to capture the ionosphere disturbance.

The anomaly spike on the oscilloscope lasted for 17 seconds and was later confirmed to be a beam of a radar imaging satellite.

Of course, it was not targeted interference, it just hit a perfectly related position by chance, and the equipment lacked automatic noise reduction capabilities back then.

But this is already the 21st century, and it is impossible for new equipment to still need to use hand twisting to achieve such basic anti-interference functions.

so……

Liao Yongcai raised his head and looked at the top of his head.

"Engineer Guo."

His originally relaxed expression became serious:

"Is this situation happening all the time?"

Guo Lin shook his head:

"The problem is here... it's intermittent, and it depends entirely on luck when it comes to reappearance."

"That's right."

Liao Yongcai took a deep breath:

"I speculate that the anomaly band of Array 3...is someone interfering with us with phase conjugated waves."
