Chapter 1366 The Past of "Project 640"
"Um?"
Liao Yongcai never expected that there would be topics 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 is a serious written report after all, and considering that most of the descriptions come from the memories of the parties involved, there is no need to add much detail.
Chang Haonan smiled:
"When I asked the Beijing Space Control Center to do a 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''s already-
As the first attempt to build a strategic early warning system in China, although the 7010 project hastily been completed, it has been truly put into use. Compared with the "Counterattack No. 1" interceptor missile that is also an anti-missile interception project and only stays in the verification stage, it is also a "Vanguard One" interceptor missile and "Pioneer" that are both an anti-missile interception project and only stays in the verification stage. "The super anti-missile cannon is closer to its full body state, leaving behind a lot of valuable experience.
Some of this even affected the later construction of the Air Force air defense system.
It is obvious that you can easily retrieve information about "finding someone to know" and it 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, although he looks like no one knows the 7010 radar better than me, he can only be regarded as a reserve backbone who was being vigorously trained by the organization when the incident happened, and is not a member of the management team of Xuanhua Radar Station.
Now seeing Chang Haonan''s appearance as if he was in control, Liao Yongcai was disconfidant.
"It''s true that the conclusion is."
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 already used to this kind of scene, and continued to explain without waiting for the other person to speak again:
"In the past two years, my country launched its own synthetic aperture radar satellite. Because its main functions are local disaster prevention and mitigation and resource exploration..., 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, the interference of a single satellite in the SAR system to ground radar will not exceed the statistical threshold of -6dB at 0.002% of the time ratio, and if it is adopted, it is more common in practical applications. Scan or stripe operation mode, the interference generated 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 can be discovered.
However, even though I realize it, I still want to struggle:
"If the satellite''s transmission power is stronger..." Chang Haonan of course knew what he wanted to say, so he waved his hand immediately:
"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 took a gesture of being reluctantly convinced, and asked:
"That''s the real reason..."
Chang Haonan did not give a direct answer, but suddenly asked:
"The situation at that time is actually very similar to that now, isn''t it?"
"Um?"
Liao Yongcai was stunned at first, raised his head in confusion, but then he immediately understood what the other party wanted to express:
"What you mean is that the other party set up an ambush during our debugging process, and then induces defects through interference signals at a specific time, which causes 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. ”
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 song, one content, one in 6, one book, one bar, one reading!
After a while of red warmth, I couldn''t help but sing a word about birds singing and flowers:
"That''s fucking..."
Chang Haonan was already preparing to go to the other side to see Guo Lin and the others'' work, but suddenly he heard this sentence, and turned his head curiously and looked at the other party with a shocking look.
Since graduating from a doctorate and taking up leadership position, few people have expressed their feelings in front of him.
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 Pentagon delegation to visit, including 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 uncommon.
Moreover, 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 yet. 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.
As a result, 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, 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 different from the real fall point. Kilometers, even more accurate than the range published by Americans themselves…”
"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 later... Looking back now, it may be inseparable from what you just said."
While speaking, Liao Yongcai didn''t know when he raised his head and looked towards the Yanshan Mountains to the east.
Although I was in an underground control center where there was no sunlight, I seemed to see Huangyang Mountain shrouded in the night again, and the Xuanhua radar station with bright lights. I saw the indicator lights flashing, technical parameters jumping, and I saw the footsteps running and commanding The institute was busy, and saw soldiers patrolling down the mountain and staring at every corner with vigilance...
Although Chang Haonan has not experienced that era personally and is not easy to empathize, he can also understand the other person''s mood a little.
He sat next to the other party and comforted him:
"There may be other factors in the dismount of the 7010 radar, but in the final analysis, it is because the 640 plan of the parent project is suspended... It is too luxurious to use a large radar with an antenna area of ??more than two basketball courts to conduct aerospace measurement and control."
"But this time, the superiors are determined to build a strategic early warning system... If nothing unexpected happens, you should have the opportunity to personally direct the new generation of anti-missile radar before retirement..."
