Chapter 1366 The Past of "Project 640"
"Huh?"
Liao Yongcai never expected that there was still topic related to him.
He glanced at the young man in front of him, who was only in his early 30s, and he didn't look like a witness: "You know this too?" >
Guo Lin did mention a brief story about the past in the report, which is a proof of their analysis conclusions.
But it was a serious written report after all, and considering that most of the descriptions came from the memories of the parties involved, there was no need to add much detail.
Chang Haonan smiled:
"When I asked the Beijing Space Control Center to conduct mutual correlation test yesterday, I found someone I knew and retrieved the information from that year..."
This sentence shocked Liao Yongcai directly.
Due to the long-term lack of information, and the director of a radar station is not considered a scientific researcher, Guo Lin did not have time to fully introduce it just now, so he actually didn't know much about Chang Haonan.
I only know that I am a very powerful guy who can lead such an important military project at a young age.
As for how powerful it is, there is indeed no specific concept before.
But now it has already been done—
As the first attempt to build a strategic early warning system in China, although the 7010 project has been completed hastily, it has been truly put into use after all, and compared with the same anti-guidance The interception project, the "Counterattack One" interceptor that only stays in the verification stage, and the "Vanguard" super anti-missile cannon are closer to the full body state, leaving a lot of valuable experience.
Some of this even affected the later construction of the Air Force air defense system.
Able to easily retrieve information about such projects by "finding someone to know" and sounds like a core information involving work details, it is obviously a saying that it is powerful.
"But..."
For a moment, Liao Yongcai was even a little afraid to make a judgment.
After looking back for a long time, I still asked the doubts in my heart:
"I remember that the final conclusion that was officially submitted to the upper part of the station should be the signal interference of a synthetic aperture radar satellite?"
In fact, don't look at him now, he looks like no one knows better than me about the 7010 radar. When the incident happened, it was only considered a reserve backbone who was being vigorously trained by the organization, and was not a member of the management team of Xuanhua Radar Station.
Now seeing Chang Haonan's appearance of being in control, Liao Yongcai himself was disconfidant. "It's true that the conclusion is this." Chang Haonan answered while watching Guo Lin busy around him:
"But I took out some of the key outputs and analyzed them again, and found that there were some problems with the conclusions of that year..."
The expression on Liao Yongcai's face was even more shocked.
The archived report conclusions are equivalent to being recognized by superiors.
When many of the parties involved are still alive, they cannot be overturned by just one or two words.
The vast powers of magic may not be enough to describe this situation.
It's almost the same with your hands and eyes.
Chang Haonan is used to this kind of scene, and continued to explain without waiting for the other side to speak again:
"In the past two years, my country launched its own synthetic aperture radar satellite, because it is mainly The function is for local disaster prevention and mitigation and resource exploration..., so the possibility of electromagnetic signals interfering with ground equipment has also been considered. "
" Finally, it was found that even if the spotlight mode is used, SAR The interference of a single satellite in the system to ground radar will not exceed the statistical threshold of -6dB at 0.002% of the time ratio. If the scanning or striping operation mode is used, the interference will be generated. It will be further reduced."
In fact, when he heard this, Liao Yongcai realized the problem.
Everyone is skilled, so the other party can't just make a few data to deceive themselves.
The interference intensity cannot reach the statistical threshold, which means that even if the radar does not adopt additional filtering and noise reduction methods, there will be no error parameters that are sufficient to be discovered.
However, even though he realized it, he still wanted to struggle:
"If the satellite's transmission power is stronger..." Chang Haonan certainly knew what he wanted to say, and immediately Waving his hand:
"The current satellite-borne SAR payload is indeed much more refined than more than 20 years ago. The model we tested is relatively small, so the transmission power is not as good as the SIR-B satellite you analyzed back then, but there will be no order of magnitude gap. , not to mention that the interference intensity we calculated is actually far below the threshold. "
Liao Yongcai was not prepared to be stubborn to the end. After gaining a new explanation, he went downhill and showed a look of barely force. The convincing gesture asked:
"The real reason..."
Chang Haonan did not give a direct answer, but suddenly asked:
"At that time The situation is actually very similar to now, isn’t it?”
"Huh?"
Liao Yongcai was stunned at first, raised his head in confusion, but then immediately understood what the other party wanted to express:
"What you mean is that the other party is too During our debugging process, an ambush was set up, and then defects were induced by interference signals at a specific time, which caused abnormal equipment operation? "
Chang Haonan nodded: "At present, This should be the most reasonable explanation, and it also conforms to the content recorded in relevant historical materials. Unfortunately, the original parameters during the debugging process were not completely preserved, so it cannot be 100% confirmed. "
< br>
That being said, it is only due to the rigor of a technician.
In fact, he is almost 90% sure that the conclusion he has drawn is correct.
Liao Yongcai also obviously agreed with this statement, showing an indignant expression.
No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!
After a little warm after being alone, I couldn't help but sing a word about birds singing and flowers:
"What a fuck..."
Chang Haonan was already preparing to go to the other side to see Guo Lin and the others' work. Suddenly, he heard this sentence and turned his head curiously, using the shock of curiosity. He glanced at the other person with a doctorate degree and had taken up leadership position, few people have expressed their feelings in front of him like this.
Liao Yongcai sighed and explained: "The international situation in that year was quite special... In September 1980, in order to reflect military mutual trust, we also specially invited a representative from the Pentagon. The tour of the group includes the 7010 radar station."
Obviously, this is another story of "Brothers exchange hearts with you, you play with your brains."
But at that time, it was not unusual.
In addition, the 7010 radar began antenna installation and array debugging in 1976 and entered trial operation in 1977.
At that time, the two sides had not established diplomatic relations, and it was normal for others to bury a mine for the key national defense projects that you imagined.
As for what happened later, I can only blame myself for not being vigilant enough.
That visit was an ice-breaking journey for exchanges between the two armies, and it should have been conducted completely in line.
So the Chinese delegation only visited the Hawaiian base far away from North America, but allowed the other party to directly enter the most core secrets.
"From the perspective at that time, the performance of the 7010 project was actually very advanced."
After a moment of silence, Liao Yongcai continued: "In July 1979, the At that time, our station coordinated and cooperated with the 110 radar in Yunnan Province and continued to track the trajectory of the Sky Laboratory's re-entering atmosphere. The final calculated fall location and fall time are only about 100 kilometers away from the real fall point, even more than the Americans. The scope you publish is accurate..."
"In January 1983, when Moscow did not announce the detailed orbit parameters, we were the first to give the fall trajectory of the Universe-1402 nuclear-powered reconnaissance satellite, and judged that it would not pose a threat to densely populated areas..."< "So we didn't understand it very well when the radar was dismantled and the radar station was removed... Looking back now, it may be inseparable from what you just said."
Speak During this period, Liao Yongcai didn't know when he raised his head and looked towards the Yanshan Mountains to the east.
Although I am in an underground control center where there is no sunlight, I seem to see Huangyang Mountain shrouded in the night again, and the Xuanhua radar station with bright lights. I see the indicator lights flashing and technical parameters jumping. When I was running around and busy in the command post, I saw the soldiers patrolling down the mountain and staring at every corner with vigilance...
Although Chang Haonan had not experienced that era personally, it was not easy to empathize with it, but You can also understand the other person's mood a little.
He sat next to the other party and comforted him: "The 7010 radar has some other factors, but in the final analysis, it is due to the suspension of the 640 plan for the mother project... a large-scale antenna area of more than two basketball courts is used. Radar is too luxurious to engage in aerospace measurement and control. "
"But this time, the superiors are determined to build a strategic early warning system... If nothing unexpected happens, you should still have a chance before retirement Personally command the new generation of anti-missile radar..."
