"I really don't know. I'll have to ask later." Zhou Meng explained awkwardly, "My brother arranged for me to be in there directly. I really haven't asked about this."
"Your brother is the boss? The one just now?" Cai Yeer asked with a strange look on her face: "Aren't you an only child? When did you have a brother? How come I didn't know?"
"Yeah!" Zhou Meng nodded: "I recognize it."
"Recognized???" Cai Yeer added a long 'oh': "I understand, so that's how it is."
"I seemed to be feeling pretty good just now." Cai Yeer had an expression that showed she understood.
"What are you thinking? My brother has a wife. Didn't I just tell you that?"
"It's okay, we can grab it if we can." Cai Ye'er winked.
"Don't talk nonsense. If my brother finds out, he will beat me to death. You can't make such a joke casually. My sister-in-law treats me very well."

A research center!
In a not-so-large conference room, there were several rows of people sitting there, young and old, some wearing glasses, some without, some with white hair, some with rosy cheeks and some with green temples!
"Everyone is here, Mr. Su, let's start!" said a white-haired old man in his 60s, wearing a sky blue military uniform with two stripes on his shoulders!
"Okay, then I will explain it to you and my colleagues!" A spirited old man in his seventies, dressed in dark gray and wearing a pair of reading glasses, stood up from the middle of the first row!
"......" The conference room fell silent instantly.
"Hello everyone, maybe many of you know me, but maybe you don't, so let me introduce myself to you. My name is Su Anguo. Now I will explain to you the latest S-wave radar designed by our GB Research Institute!"
"Is it Mr. Su?" Some younger researchers in the audience looked at the nearly seventy-year-old man curiously, with respect and admiration in their eyes.
Speaking of Su Anguo, he is a hurdle that can never be avoided on the radar of the flower growers.
Su Anguo, electronics scientist.
Born on December 1, 1927, from Nantong, Jiangsu Province.
In 1953, he graduated from the Radar Department of a Communications Engineering College (University of Electronic Science and Technology of China).
From 1984 to 1992, he served as the president of a certain University of Electronic Science and Technology, and has long been engaged in theoretical research and engineering practice in radar and signal processing.
In the early 1960s, he presided over the development of the first microwave meteorological radar in China. In the early 1970s, he invented the "impact flashover method" for measuring buried power cable faults, which solved a major problem for the power supply department.
Since the mid-1970s, systematic and in-depth research has been conducted in many aspects such as digital signal processing, statistical signal processing, array signal processing and adaptive signal processing.
We have 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 their application in relevant factories, institutes and troops, and deployed them in a variety of radars.
He is committed to the research of spatial signal super-resolution, radar imaging and space-time two-dimensional signal processing, and has proposed relatively systematic and complete concepts and methods.
......
He was elected as an academician of the Academy of Sciences in 1991.
He served successively as deputy director of a teaching and research section, department director, and vice dean of a university.
He has served as a member of the subject review group of the Academic Degree Committee, a member of the review group of the National Natural Science Foundation of China, and a member of the National Outstanding Young Scientist Fund Committee.
He is currently the director of the Academic Committee of the Key Laboratory of Radar Signal Processing, consultant to the Electronic 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 is my idol. Today I get to meet him in person!" A researcher looked at Su Anguo with longing.
"Yes, today I finally saw him in person. I have always admired Mr. Su!"
At this time, Su Anguo walked to the center with a laser stick in his hand, pointed at the large screen behind him and said, "Let me first explain to you the working understanding of the S-wave radar, so that everyone can have an idea in their mind!"
"S-wave radar uses the S-waves already in space to detect targets by reflecting the echoes formed by the target."
"Whether it is without a transmitter or the light waves reflected from the target are made with the help of the existing S waves in space, this kind of radar is called S-wave radar, also known as non-radiation line source radar."
Su Anguo paused for a while and looked at the audience, allowing everyone to digest what he had just said!
"Everyone, please look at the screen!" Su Anguo used the laser stick in his hand to slide the large screen behind him.
"Because radar itself does not radiate radio waves, this leads to changes in radar positioning methods, information processing and other related issues."
Su Anguo paused, turned off the laser rod in his hand, turned around and continued: "In addition, this S-wave radar is a stealth radar. The anti-radiation missile, the nemesis of radar, tracks radar radiation waves and attacks them."
"Light wave radar continuously radiates radio waves into space, which will prevent anti-radiation missiles from finding the radar's location. Therefore, light wave radar is a truly invisible radar, without the need to use stealth materials or reduce the scattering, reflection and diffraction waves of the radar device itself."
"......"
"What I just said is the working principle of S light wave radar. Later I will tell you about its approximate performance!" Su Anguo has already turned off the screen.
"The main technical indicators of light source radar are: long detection distance, high precision, real-time detection of multiple targets (including aircraft and missiles), all-round and all-weather monitoring, coexistence of fixed and fast-moving types, and installation on the ground, aircraft and ships."
"Its advantages are good concealment, strong mobility, low cost, and resistance to enemy reconnaissance and anti-stealth."
"S-wave radar has many advantages in anti-reconnaissance, anti-interference, anti-stealth aircraft and cruise missiles, anti-anti-radiation missiles, and anti-low-altitude penetration, and is an important field of modern radar research."
“It is positioned in the fields of navigation, aviation, etc.”
"......"
Half an hour later.
Su Anguo finally finished talking about the approximate parameters and said: "What I have said above is the approximate parameters of the S-wave radar. Everyone here is the backbone of our China!"
"Some are masters in materials, some are masters in processing, and some are experts in electronics. We invited everyone here today mainly to ask for your help and advice. Now that the S-wave radar has been designed, we have also tried to produce one ourselves, but the finished product is far from what we designed!"
"There are mainly two problems: materials and processing precision. Because the S-wave radar is a large radar, and the accuracy requirements are too high, these two problems are difficult to solve. The entire project can be said to have come to a halt!"
