The Red Era, the Opening University Speech

Chapter 212 Pulse Doppler Radar

The next day, early.

After carefully getting up from the bed and covering the still sleeping Wang Ya with a blanket, Li Mu began to wash up. After exercising around as usual, he returned home and prepared breakfast.

When the aroma of breakfast filled the whole house, Wang Ya woke up and walked out of the room.

"Time for breakfast." Li Mu heard her coming out, turned around with a smile, and said with a gentle look.

Wang Ya looked at him and thought of last night, her face turned red again.

Li Mu couldn't help but be distracted again.

——What should I do if I have a lovely wife at home and she gets shy easily?

While having breakfast, Li Mu talked about the savings matter which he forgot to mention because he was too "busy" last night.

Seeing Li Mu casually take out a deposit slip with more than 8 yuan written on it and saying that the amount would increase every once in a while in the future, Wang Ya couldn't help but be shocked for a while.

But only for a moment.

She knew how important the research Li Mu was doing was to the country.

As for the donation, she had even less objection.

In this day and age, having so much money in your hands is actually of no use at all, and you may even run the risk of being labeled.

Although Li Mu's status would not be affected by a little rumor, why bother himself with trouble?

……

Go to the research institute as usual to carry out research and development work.

The current research is proceeding relatively smoothly and there will not be any major breakthroughs in the short term.

Li Mu checked everywhere and saw that no one had encountered any problems for the time being, so he went to the game development center of Beijing Institute of Technology to continue providing guidance on game development.

In terms of game design, graphics rendering, physics engine, user interaction, audio processing, etc., this group of students has accumulated a certain amount of knowledge and is fully capable of handling current research and development tasks.

Occasionally, if I encounter difficult problems, I can solve them by myself.

After discovering this, Li Mu was not disappointed, but was very happy about their growth.

No matter how capable a single person is or how hard he works, he can never be as good as a team. The name "coder" is not for nothing.

Of course, the key core codes still need his guidance, and his ability in this area needs to be strengthened.

……

After having lunch at the Beijing Institute of Technology canteen at noon, Li Mu was about to return to the game R&D center when he suddenly saw Qian Shuyan, Zhao Jiuzhang and a professor wearing glasses, with an elegant temperament and a square face walking towards him.

He took the initiative to greet them and asked, "President Qian, Director Zhao, why are you here, and this is..."

"I'm the director of the Radar Research Institute, Shen Zhongyi. You must be Li Mu, right? You're really a handsome man." Professor Wen Ya, who was wearing glasses, said with a smile without waiting for Qian Shuyan and Zhao Jiuzhang to introduce themselves.

Li Mu said: "You are too kind, Director Shen."

"It's not an exaggeration at all. Several of my old friends and semiconductor experts and professors I know all praise you highly and say that you are the number one in the semiconductor industry in our Xia country today!" Shen Zhongyi said with a smile.

To be honest, Li Mu's age is too misleading. Without knowing the truth, it is hard to believe that he is a super scholar who has achieved so many things.

If a person said it, he might not believe it.

But he found so many people who praised Li Mu highly that he had no choice but to believe it.

Shen Zhongyi continued, "Okay, I won't say polite words. This time I came here to invite you to participate in one of our research as a special expert in semiconductors."

"Okay, I'll join." Li Mu agreed without any hesitation.

Shen Zhongyi and Qian Shuyan Zhao Jiuzhang were all a little surprised by his straightforwardness. He agreed so readily without asking any questions?
Seeing that the three of them were a little confused, Li Mu smiled and explained, "It just so happens that I am not busy with my research recently. I can just come and keep an eye on it regularly. I have plenty of time. Besides, you are the director of the Radar Research Institute. You came to me to do research in the field of radar. I am very interested in this."

"Okay, okay, then when can you come to the institute?" Shen Zhongyi said happily.

"Right now." Li Mu said with a smile.

……

It can be seen that Shen Zhongyi is a practical man.

When he heard Li Mu say that it would be possible now, he immediately took people to the Radar Research Institute.

Because of the special nature of radar, it may cause harm to the human body, so the research institute is located in the suburbs far away from the downtown area.

It took the two of them an hour to reach the gate of the Radar Research Institute.

After the inspection, Shen Zhongyi first brought Li Mu to the office, made a cup of tea, and then hurriedly summoned the backbone of the Radar Institute to a meeting.

After taking a sip of tea, the tea leaves were just ordinary tea leaves.

The furnishings in the office are also very simple, reflecting the good quality of simple struggle of this era.

I didn't have to wait too long before I heard a burst of dense footsteps coming from outside.

A group of experts from the Radar Research Institute filed in, first glanced around the office, and then asked Li Mu, "Young comrade, where is Consultant Li Mu? Is he out?"

It's not their fault for admitting their mistakes. It's just that Li Mu's face is too young. Even though he is married and his temperament has matured a lot, it's hard for people to associate him with words like "the first person in semiconductors" and "authoritative expert".

It's like a boxing match. If Hawking were to stand opposite Tyson, no one would think that Hawking would be his opponent.

"This is consultant Li Mu, an authoritative expert in the semiconductor industry." Shen Zhongyi, who had just been squeezed behind by the crowd and was unable to come in, squeezed out and explained breathlessly.

This explanation made the dozen or so people in the office stare with disbelief in their eyes:

"Director, you are serious, right? He is Consultant Li Mu?"

"An authoritative expert professor, the best in the semiconductor industry?"

"Wait, I seem to have seen this young man in the newspaper. He has made many inventions and is known as the King of Inventions."

"That doesn't prove that he's good at semiconductors. Radar research isn't just about small appliances and toys..."

……

The extensive publicity in newspapers across the country had a very good effect.

At least now many people who are not familiar with him know his title as the King of Inventions and no longer regard him as a nobody.

However, there are pros and cons to this matter.

The advantage is that everyone knows you and knows that your invention is amazing.

The disadvantage is obvious: people only know that your invention is great.

It's a stereotype.

Facing everyone's doubts, Li Mu smiled and shook his head:
"I am indeed Li Mu. I am currently working as a consultant at the Semiconductor Research Institute. Of course, I am not an authoritative expert or the best person. I just have some knowledge of semiconductors."

This sentence made everyone quiet down, and everyone looked at each other.

Even with Li Mu's personal confirmation, it still didn't seem real. They had seen geniuses before, but no matter how talented a person was, he wouldn't be so powerful in his twenties.

"Excuse me, Consultant Li, how old are you this year?" a researcher in his 30s couldn't help but ask.

Li Mu smiled slightly: "Twenty-three."

Well, the last possibility of having a young face has also been ruled out, that is, being as young as one looks.

"Okay, sit down first. You are here to discuss and research, not to inquire about Li Mu's personal situation." Shen Zhongyi coughed heavily.

After hearing this, everyone took their seats one after another.

Because there were not enough seats, many people brought small stools and sat in a circle around.

Shen Zhongyi first introduced them to Li Mu one by one: "This is Zhang Guoying, the deputy director of the Radar Research Institute, and this is Professor Liu Yongtan, Professor Wang Ben, and Professor Zhang Haishi..."

"Hello, professors. I look forward to your guidance in the future." After Shen Zhongyi finished his introduction, Li Mu stood up and bowed slightly.

After all, he is young, and even if he has the title of a specially invited expert, he still needs to be polite, otherwise he might give people an impression of arrogance.

In the future he will still rely on these big guys to help him with research, so he can't offend them.

Shen Zhongyi was very satisfied with Li Mu's performance. He nodded and said, "Okay, let's stop talking nonsense and get started."

The Radar Institute's current research project is about the design and development of Doppler radar.

This type of radar, also known as pulse Doppler radar, is a radar that uses the Doppler effect to detect the position and relative motion of moving targets.

In 59, the General Electric Company of the United States developed a ballistic missile early warning radar system that could track high-altitude missiles 3000 miles (about 4828 kilometers) away and 600 miles (about 966 kilometers) away with an early warning time of 20 minutes.

Worldwide, only M Emperor has made a major breakthrough in this technology.

Even Big Brother has not yet been developed.

Shen Zhongyi first briefly introduced the research project, and then said:

"Doppler radar contains multiple circuit structures such as range gate circuit, single-sideband filter, main beam clutter suppression circuit, etc."

"At present, our research on them is relatively slow due to technical and equipment reasons."

"But your successive breakthroughs in semiconductors have made us much more advantageous than Emperor M in this area."

"So I think that with your participation, the research speed of Doppler radar will be greatly accelerated and we can catch up with Emperor M!"

After he spoke, he looked at Li Mu with burning eyes.

The same went for the others, who stared at Li Mu with anticipation.

The advantages of integrated circuits were not obvious in the early days, but as the degree of integration became higher and higher, anyone could see that it would be the development direction of various precision instruments in the future.

Facing everyone's gaze, Li Mu hesitated for a moment, then said: "I think the original experimental goal of benchmarking Emperor M is a bit inappropriate."

"Is it inappropriate? Then it's okay to lower the requirements a bit." Shen Zhongyi was stunned for a moment, then said.

He also knew that with Xia Country's current technological level, it would be difficult to achieve this goal.

But after hearing what Li Mu said, he couldn't help feeling a little disappointed.

Other experts and professors also sighed in their hearts.

Looking at the disappointed eyes of the crowd, Li Mu pinched his chin and said:

"Why should we lower the requirements? We should raise them!"

"With our current level of semiconductor technology, we must be at least ten years ahead of Emperor M in integrated circuit technology."

"With so many advantages, the performance is almost completely superior. Whether it is the warning range, warning altitude, or warning time, it has been improved by at least 2 times!"

The office fell into silence following Li Mu's words.

2 times, what does that mean.

The tracking range of 6000 miles and 9656 kilometers far exceeds the maximum diameter of the Xia Kingdom map of more than 5500 kilometers, and can even fully cover the surrounding sea areas.

If it can be developed, those hostile forces that dare to invade Xia’s airspace will be exposed.

"Li, Consultant Li, you are not kidding, are you?" Deputy Director Zhang Guoying stammered.

It’s not that he didn’t believe what Li Mu said, but the data was too exaggerated. The detection distance and detection height of the radar were generally improved by hundreds or thousands.

Exponential growth, unheard of!

Li Mu smiled and said:

"Of course it is true, and I am not making this goal without basis."

"I am currently studying applied physics with Professor Qian Wu, and I also have a certain understanding of the aerospace field."

"I have previously completed the development of an automated guidance system and am preparing to continue in-depth research on surface-to-air D missiles, so I have some experience with radars."

"So your teacher is Professor Qian Wushi!" Zhang Guoying said in surprise.

The three words "Master Qian Wu" still carry a lot of weight in the country.

Although a famous teacher may not necessarily produce outstanding students, at least the fact that Li Mu was accepted as a student by the teacher shows that his ability is not exaggerated.

So, a 2-fold data increase is indeed possible!
Everyone was also suddenly aware of it, but soon found that something seemed wrong.

Wait, isn’t he the number one person and an authoritative expert in the semiconductor industry? Why would he be studying applied physics with Master Qian Wu?
Shen Zhongyi also noticed this and couldn't help but ask curiously, "Advisor Li, you even know applied physics?"

"Not really, not really. I just dabbled in it a little. I haven't even graduated from graduate school yet." Li Mu said modestly.

When everyone heard this, they all smiled bitterly.

A graduate student can solve the automated D-missile guidance system before he even graduates. Even a doctoral student would be dumbfounded by this level!

……

After staying at the Radar Research Institute for three or four hours, Li Muxian briefly learned about the current research status and progress of Doppler radar.

Then he returned to the Semiconductor Industry Research Institute and started recruiting people.

He can provide guidance for the development of multiple integrated circuit projects such as range gate circuits, single-sideband filters, and main beam clutter suppression circuits, but he is definitely not good at practical operations.

It’s not that I can’t, but there’s not enough time.

He first came to Huang Xinhua and asked him to recommend a few people to help.

Huang Xinhua said: "Professor Xu and Professor Lu are as good as me in semiconductors. They should be able to help you solve the difficulties in the early stages."

"You can also take Liu Ze and Wang Yang with you. Although their skills are not good enough, they can do odd jobs."

"Okay, then let's do as you say, Professor Huang." Li Mu recalled that Professors Xu and Lu did perform well in previous research.

As for Liu Ze and Wang Yang, they have also made great progress and there is no problem at all in following them for research.
