Chapter 1363 The dialogue between metal and silicon
at the same time.
Hundreds of kilometers away.
The spring breeze of Qilian Mountains was wrapped in fine sand and slapped on 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 is a photo of some years in the notebook. Although it is not very clear, it can still be seen that there is a semi-buried building three kilometers away, like a weathered steel skeleton.
That was the 7010 radar control center that started in 1974, but only about 60% was completed and never entered into the used 7010 radar control center.
On a hillside a little further away from the camera, a huge cement base outlines a jagged silhouette in the setting sun in the afternoon.
This was taken as a memorial when he first arrived at this radar station—
The functional parts of the radar station are all in the new camp behind him, so these wreckages of the last century were listed as "memorial areas" and are not strictly kept confidential.
In the next twenty years, the maneuverable early warning radar that replaced the 7010 radar was replaced by the earliest parabolic antenna to the Casegren antenna, and then replaced by the current plane phased array antenna.
But outside the wall, time was as frozen by wind and sand, and no obvious changes occurred.
Liao Yongcai has believed more than once that the radar station he is responsible for will not have the day to assume the original mission.
The indicators of the new radar are first-class, but after all, they are only models used to cooperate with the Air Force''s local guides. The core function is still to play a tactical role, protecting the few big cities in Qingtang and Longyuan areas.
It is completely incomparable to the strategic value expected to be played by the 7010 radar back then.
However, in just a few short months, everything has changed drastically.
The memorial area that was originally planned to be converted into a tourist attraction was reblocked, and the transport truck that once came only 1-2 times a week has become a regular visitor every night.
Apart from the usual basic supplies such as food fuel, the remaining space is filled with various equipment and electronic components.
Of course, there are also engineers.
Thanks to the earlier development time of the 7010 radar, extremely huge space was left behind the antenna to accommodate various signal processing and command communication equipment at that time.
For the new model in the 21st century today, it seems more than enough.
It also saves the trouble of damaging construction.
Until recently, the installation of antennas has begun, some large machinery has entered the site to cut and replace reinforced concrete bases that are outdated due to lack of maintenance.
Regarding the ultimate goal of this big move, Liao Yongcai currently only knows that it is related to the hypersonic weapon test to be conducted.
His subordinates were told that the radar station would add orbital measurement and control departments to contribute to the development of the aerospace industry.
Considering that the 110 ultra-long-range single-pulse tracking radar located in Yunnan Province has indeed been converted to civilian use in previous years, this statement has a certain degree of credibility.
"Director Liao, the joint test data has come out."
Just as Liao Yongcai was feeling alone, a voice suddenly came from below.
He turned his head a little and found that the person coming was Guo Lin, chief radar designer of Electronic Technology Group.
The latter is climbing up the platform along the maintenance ladder:
"The electromagnetic background nearby is very different from that in Jinling. Our operators have never been able to adjust the electric sweep antenna to an 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 calculated through some parameters.
This process is inevitably affected by the external environment.
Especially during the preliminary debugging process, due to the lack of zeroing point, small deviations can often lead to very outrageous jumps in results.
So, it’s no wonder that many electronic engineers believe in some metaphysics after working.
For example, what is Jihun Joy or something.
"Okay, let''s go."
As an old technology, this feeling of being needed made Liao Yongcai very satisfied, and he was instantly full of energy.
The two of them returned to the ground quickly, then jumped onto a jeep and rushed towards the radar control center in the distance.
…
Even if the space is relatively abundant, it is impossible to set up a brand new control center in an underground building reserved by a radar.
Therefore, most of the equipment was updated in situ based on that year.
Due to the tight time, many traces of the past have been left.
For example, metal pipes that are sleeping at the bottom of a deep well.
It was originally laid to protect huge data transmission lines, but now they are all fiber-optic transmissions, so the entire maintenance well is useless.
Liao Yongcai was worried that an accident would occur after walking and passing by. He mentioned it several times and wanted to fill it in, but he never spared any staff.
"Mr. Guo, Director Liao." Seeing the two of them walking 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 check it out."
Guo Lin did not make any moves. He probably had seen it on the computer before, but he just signaled to hand the file directly to Liao Yongcai.
When the latter was taken into his hand, he noticed that a square gauze was sticking to the other party''s wrist, which seemed to be a mark of burning by high-energy microwaves from the edge.
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.
No mistakes, one song, one content, one in 6, one book, one bar, one reading!
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."
