"I really don't know. I'll have to ask later." Zhou Meng explained a little awkwardly: "My brother arranged for me directly. I never asked about this."
"Your brother is the boss? Is that the one just now?" Cai Ye'er asked with a strange look: "Aren't you an only child? When did you have a brother? Why didn't I know?"
"Yes!" Zhou Meng nodded: "I recognize it."
"Recognize???" Cai Ye'er added a long "oh": "I understand, so that's what happened."
"I seemed to be feeling pretty good just now." Cai Ye'er said with an "I understand" expression on her face.
"What are you thinking? My brother has a wife. Didn't I tell you just now?"
"It's okay, you can grab it if you can." Cai Ye'er winked.
"Don't talk nonsense. My brother will find out later and will beat me to death. This joke cannot be made casually. My sister-in-law is very good to me."

A research center!
In a very large conference room, there were several rows of people, old and young, sitting there, some wearing glasses, some not wearing glasses, some with gray hair, some with red faces and green temples!
"Everyone is here, Mr. Su, let's get started!" A white-haired old man in his late 60s, wearing a sky-blue military uniform with two stripes on his shoulders, said!
"Okay, then I will explain it to you and my colleagues!" A vigorous old man in his late seventies, wearing dark gray clothes and a pair of reading glasses, stood up from the middle of the front row!
"..." The conference room fell silent instantly.
"Hello everyone, maybe many people know me, but maybe they don't know me, so let me introduce myself to you first. My name is Su Anguo. Now I will explain to you the latest designed s-light wave in our gb research institute.
radar!"
"Is it Mr. Su?" Some younger researchers in the audience looked at the nearly seventy-year-old man curiously, with respect and reverence in their eyes.
Speaking of Su Anguo, this is a threshold that can never be bypassed on the radar of flower growers.
Su Anguo, electronics scientist.
Born on December 1, 1927, from Nantong, Jiangsu Province.
Graduated from the radar department of a certain communications engineering college (University of Electronic Science and Technology of China) in 1953.
From 1984 to 1992, he served as the president of a University of Electronic Science and Technology and has been engaged in theoretical research and engineering practice in radar and signal processing for a long time.
In the early 1960s, he presided over the development of China's first microwave weather radar. In the early 1970s, he invented the "impact flashover method" for detecting faults in buried power cables, which solved a major problem in the power supply department.
Since the mid-1970s, systematic and in-depth research has been carried out in digital signal processing, statistical signal processing, array signal processing and adaptive signal processing.
It has successively developed 0.5us and 0.2us radar moving target displays, radar antenna adaptive sidelobe cancellers, radar moving target detectors, programmable moving target detectors, etc., and promoted them to relevant factories, institutes and troops, and deployed them.
for a variety of radars.
Committed to research on spatial signal super-resolution, radar imaging and spatio-temporal two-dimensional signal processing, he has proposed relatively systematic and complete concepts and methods.
...
In 1991, he was elected as an academician of the Academy of Sciences.
Served as deputy director of the teaching and research section of a university, department head, and vice president.
He once served as a member of the academic degree committee’s subject evaluation group, a member of the natural science foundation committee’s evaluation group, and a member of the National Science Foundation for Distinguished Young Scholars committee.
He is currently the director of the Academic Committee of the Key Laboratory of Radar Signal Processing, consultant to the Electronic Science and Technology Committee of the Ministry of Information Industry, consultant to the Science and Technology Committee, and consultant to science and technology development and talent training.
"I've only heard of him in legends before, but he's my idol. Today I met him in person!" A researcher looked at Su Anguo longingly.
"Yes, I finally met the real person today. I always admire Mr. Su!"
At this time, Su Anguo held a laser rod in his hand, walked to the C position, pointed at the large screen behind him and said: "Let me first explain to everyone the working understanding of S-light wave radar, so that everyone can have an idea!"
"S light wave radar, it uses the existing S radio waves in space to detect the target by reflecting the echo formed by the target."
"Whether there is no transmitter, or the light wave reflected from the target relies on the existing S-wave in space, this kind of radar is called S-light wave radar, also called non-radiation line source radar."
Su Anguo paused for a while and looked at the audience to let everyone digest what he just said!
"Everyone, please look at the screen!" Su Anguo directly used the laser wand in his hand to slide the big screen behind him.
"Since the radar itself does not radiate radio waves, this leads to changes in radar positioning methods, information processing and other related issues."
At this point, Su Anguo stopped, turned off the laser stick in his hand, turned around and continued: "In addition, this S-light wave radar is a stealth radar, and the nemesis of the radar, the anti-radiation missile, tracks radar radiation waves.
, and attack it."
"Lightwave radar continuously radiates radio waves into space, which will prevent anti-radiation missiles from finding the location of the radar. Therefore, lightwave radar is a stealth radar in the true sense. There is no need to use stealth materials and reduce the scattering and reflection of the radar device itself.
and diffracted waves.”
"..."
"What I just said above is the working principle of S-light wave radar. I will tell you about its approximate performance later!" Su Anguo had already turned off the screen.
"The main technical indicators of light source radar are: long detection range, high accuracy, real-time detection of multiple targets (including aircraft, missiles), all-round, all-weather surveillance, can coexist in fixed and fast-moving types, and can be installed on the ground, aircraft
And on the ship.”
"His advantages are that it has good concealment, strong maneuverability, low cost, resistance to enemy reconnaissance and anti-stealth characteristics."
"S light wave radar has many advantages in anti-reconnaissance, anti-jamming, anti-stealth aircraft and cruise missiles, anti-anti-radiation missiles, anti-low-altitude penetration, etc. It is an important field of modern radar research."
"Positioned in the fields of navigation, aviation and other fields."
"..."
Half an hour later.
Su Anguo finally finished talking about the approximate parameters and said: "What I mentioned above are the approximate parameters of the S-light wave radar. Everyone here is the mainstay of our country!"
"Some are masters in materials, some are masters in processing, and some are experts in electronics. I invite you all here today mainly to ask for your help. Now that the S-light wave radar has been designed, we have also trial-produced it ourselves.
One machine, but the finished product is far from our design requirements!”
"There are mainly two problems, materials and processing precision. Because S-light wave radar is a large radar, and the accuracy requirements are too high, these two problems are difficult to solve now, and the entire project can be said to have come to a standstill!"
