When I am reborn, I just want to be a top student

Chapter 219 The most important weapon of the country, Chang’e- satellite

The next day, Wang Donglai received a call from Xu Songyao, saying that the project was time-sensitive and the task was heavy, and he needed to leave immediately to participate in the project.

Now that he has agreed to participate in this project, Wang Donglai will naturally not change his mind again.

Therefore, after asking about the research location, we went directly to the research institute.

Originally, Xu Songyao was planning to send Wang Donglai there in person, but something unexpected happened and he couldn't leave at all, so he had to let Wang Donglai go alone.

According to the location given by Xu Songyao, Wang Donglai didn't take long to find the place.

After arriving at the place, he made a call, and after a while, a man walked out of the research institute.

"Hello, Professor Wang, I am Yang Shuai. Academician Yang asked me to pick you up."

Yang Shuai saw Wang Donglai at a glance, walked up to him, and took the initiative to introduce himself.

"Hello, please."

“LiDAR technology, do you know?”

Although this project is very important, they don't think it will be difficult for them.

Wang Donglai shook his head and said: "I only know that it is an aerospace engineering project, but I don't know the details yet."

Wang Donglai naturally knew about this technology. He had read so many books in the library of Jiaotong University in Tangdu, so he had naturally seen this content.

Before Yang Shuai had time to answer, Song Hui spoke up.

Song Hui stopped what he was doing, turned around and said to Wang Donglai.

After introducing Wang Donglai, Yang Shuai introduced Wang Donglai again: "Professor Wang, this is Song Hui, a doctorate from Tangdu University of Electronic Technology."

With the ability shown by Wang Donglai, he is fully qualified.

Lidar is a radar system that emits a laser beam to detect characteristics such as the position and speed of a target.

Wang Donglai's performance did not make Yang Shuai and Song Hui feel uncomfortable. After all, they were all aware of Wang Donglai's achievements.

"How many people do we have on this project?"

In terms of working principle, it is to transmit a detection signal to the target, and then compare the received signal reflected from the target with the transmitted signal. After processing, some information about the target can be obtained.

"Hello there!"

"At this moment, they may have gone to another research institute to sort out information and data."

"You should know the research content of our project, right?" Song Hui asked curiously.

"I won't let you down!"

"Academician Yang, as the general person in charge, is responsible for many projects, so Professor Lu is mainly responsible for things here."

At most it just takes a little more time.

Through chatting, Wang Donglai found out that Yang Shuai had not graduated yet and was studying for a PhD at Tsinghua University. His mentor was Academician Yang, the person in charge of this project.

Wang Donglai also nodded and said, "Hello."

Yang Shuai nodded, not surprised by this, and said: "In this case, let me briefly introduce to Professor Wang that our project is a small branch of the lunar exploration project, and is responsible for the laser A breakthrough in radar technology.”

"I've heard of your reputation. It's very impressive. I'm looking forward to your performance!"

After Yang Shuai asked, he took Wang Donglai directly to the laboratory.

Soon, the two arrived at the laboratory.

Wang Donglai was shocked when he heard what Yang Shuai said.

As soon as the words "lunar exploration project" came out, he thought of the Chang'e series, as well as the Tiangong, remote sensing and other series.

When Song Hui said this, he asked curiously.

Wang Dong took a look at the laboratory and found that Song Hui was the only one there, so he asked curiously.

"Including you, there are only eight people."

When I opened the door of the laboratory, I saw someone operating a digital delay pulse generator.

"Well, in that case, what aspects of work do I need to be responsible for, is it only mathematical modeling and algorithm research?" Wang Donglai asked curiously again.

Although Wang Donglai is younger than Yang Shuai, Wang Donglai's aura is far greater than that of Yang Shuai.

On the way, Yang Shuai asked aloud.

Wang Donglai nodded, indicating that he knew.

The two of them were walking and chatting.

"Old Song, let me introduce to you. This is Professor Wang from Jiaotong University in Tangdu. He is a master in charge of mathematical modeling and algorithms."

Because he was in Tangdu, Wang Donglai didn't plan to stay here and didn't bring much luggage.

Song Hui looked Wang Donglai up and down, with a faint smile on his face, and said hello.

Wang Donglai was not modest, and his tone revealed a hint of confidence.

“Our project this time is to upgrade the lidar mounted on the Chang’e-5 satellite of the lunar exploration project!”

"I wonder if Professor Wang knows about our project this time?"

Active remote sensing technology uses lasers as transmitting power and photoelectric detection technology. Lidar is an advanced detection method that combines laser technology and modern photoelectric detection technology.

It consists of a transmitting system, a receiving system, information processing and other parts. The emission system is composed of various forms of lasers, such as carbon dioxide lasers, neodymium-doped yttrium aluminum garnet lasers, semiconductor lasers, wavelength-tunable solid lasers, and optical beam expansion units. The receiving system uses a telescope and various forms of photodetectors, such as photomultiplier tubes, semiconductor photodiodes, avalanche photodiodes, and a combination of infrared and visible light multi-detector devices.

Using pulse or continuous wave working methods, detection methods can be divided into laser radars such as meter scattering, Rayleigh scattering, Raman scattering, Brillouin scattering, fluorescence, and Doppler according to different detection principles.

Lidar plays a great role in the military and can be said to be one of the core technologies in the world today.

Not only that, this technology is equivalent to the eyes of the mechanical age. Drones, driverless cars, or robots can all use this technology.

The country's technological accumulation in this regard is far inferior to that of foreign countries, and its technology is several generations behind.

With this information flashing through his mind, Wang Donglai nodded to Song Hui and said, "I know a little bit about this technology."

Song Hui nodded and didn't care. After all, in his opinion, Wang Donglai was only very talented in mathematics, and at most he could just add another computer.

Lidar is not a subject technology like mathematics and computers.

"Professor Wang, during research, you may need to model the problems that arise and adjust the computer algorithm. I heard that the artificial intelligence medical auxiliary diagnosis system was written by Professor Wang, and the laser slam algorithm may be needed by then. Leave it to Professor Wang."

"Of course, this is also my guess. Professor Lu and Academician Yang will be responsible for the specific work arrangements. You will know when Professor Lu comes back later."

Hearing what Song Hui said, Wang Donglai nodded and there was no problem.

Then, Song Hui continued to play with his instruments, while Yang Shuai took Wang Donglai around the laboratory to let Wang Donglai get familiar with the place.

"This is the data room. There are many journal articles and professional materials on laser radar. If you are interested and have any questions, you can come here to find them."

"Our project is actually not really a project under the aerospace engineering, it should be regarded as a spare tire."

"It's just that, as you know, Academician Yang is from Tangdu University of Electronic Science and Technology, and there are many aerospace engineering projects in Tangdu, so he fought for such an opportunity."

"It doesn't matter whether it can produce better results or not. We are not the only ones working on this project. There are also many people in Beijing who are also working on this technology."

“When the time comes, whoever conquers the technology first will be able to adopt it.”

After listening to Yang Shuai's words, Wang Donglai understood immediately.

No wonder he said why this project will stay in Tangdu, and there are only eight researchers on the project.

Yang Shuai and Song Hui are still two Ph.D. After thinking about it, Wang Donglai did not relax or change his mind.

Now that it is known that lidar technology will be used on the Chang'e-5 satellite, it is naturally impossible for Wang Donglai to paddle.

Mathematical modeling and algorithms are not a problem at all for him.

Therefore, he now needs to think about what kind of entry point he should use to help this project be completed quickly and raise lidar technology to a higher level.

Yang Shuai would never have imagined that Wang Donglai was thinking about these things at this moment.

Seeing Wang Donglai lost in thought, Yang Shuai interrupted Wang Donglai's thinking and said aloud: "Professor Wang, Professor Lu and the others are not back yet, why don't you take a look at the information first."

Wang Donglai nodded in agreement, then stayed in the information room and looked at the information.

Wang Donglai knew the principles of lidar technology, but if he wanted to improve lidar technology, he still needed to study it carefully.

Fortunately, there is a lot of relevant information here.

Wang Donglai estimated that it would only take him a few days to read through the information and he should be confident.

Thinking of doing it, he started to read.

Two hours later.

Professor Lu returned to the laboratory with several other people.

After some introduction, Professor Lu welcomed Wang Donglai’s joining.

After all, having a mathematical genius like Wang Donglai joining the team will make their research more likely to succeed.

Regarding Wang Donglai's arrangements, it was indeed as Song Hui said.

In this way, Wang Donglai strengthened his idea.

Compared with other people's work, Wang Donglai seems a bit relaxed and has more time at his disposal.

Wang Donglai did not waste this time.

I was reading books on lidar in the reference room.

With [Speed ​​Reading] and [Photographic Memory] in his possession, Wang Dong reads books very quickly.

The most convenient method is to first memorize these principles in your mind, and then use the [Brain Overclocking] skill to integrate the technologies in your mind and introduce new ones.

This is also the best way to use it that Wang Donglai came up with through repeated experiments.

Originally, Professor Lu's idea was to book a table for Wang Donglai in the evening.

However, this proposal was rejected by Wang Donglai.

After some communication, Professor Lu also gave up this proposal and chose to respect Wang Donglai's idea.

In the evening, at ten o'clock.

People in the laboratory left one after another, but Wang Donglai still stayed in the reference room reading.

"Professor Wang, there is no need to rush at this moment, you should have a good rest first!"

Yang Shuai walked in and saw Wang Donglai still reading, so he persuaded him.

"it is good!"

Wang Donglai didn't insist. Even if he read the information slowly, it would only take him a few days at most to finish reading it.

After putting the information back to its original place, Wang Donglai and Yang Shuai left the laboratory together.

Since he was not staying at the institute, Wang Donglai went directly back to the house he bought in Tangdu.

For convenience, he had already bought a house and lived there occasionally.

……

the next day.

Because he participated in this project, Wang Donglai did not have to show up at Tangdu Jiaotong University for the time being and could focus on this.

Early in the morning, Wang Donglai came to the laboratory and continued to read the information.

As time passed, other talents began to arrive.

When they saw Wang Donglai already here, everyone was a little surprised and a little impressed.

"No wonder Professor Wang was able to achieve such results with such a hard-working attitude. If he fails to succeed again, it will really be unreasonable."

"Diligence is only part of it. What's more, Professor Wang's talent is too strong. Even if others work as diligently as Professor Wang, their results may not be as good as one-tenth of Professor Wang's."

Many people are actually very curious about Wang Donglai.

The members of this research team are actually only a few years older than Wang Donglai, so they are even more curious.

One morning, several people would look at Wang Donglai from time to time, wanting to see what Wang Donglai was doing.

When you see Wang Donglai's reading speed, he often just turns the page in just a few dozen seconds.

Several people began to murmur in their hearts.

"Is reading so fast real or fake?"

"It can't be fake, right? This kind of fraud is meaningless. After all, his job is not to study these things, so he doesn't even need to read these materials."

"But if you read so fast, can you really remember it after reading it?"

"With such a great reputation as a virtual scholar, since Professor Wang can achieve such results, it is normal for him to read faster."

After a few people discussed it for a while, they put aside their curiosity and started busy with their work.

It has to be said that the people in this research team are all elites from various schools, and they do have two brushes in their hands.

It's almost noon.

Professor Lu and a middle-aged man in his fifties walked into the laboratory.

Seeing these two people, the people in the laboratory instantly became serious.

Seeing this person, Wang Donglai recognized him at a glance. He was Academician Yang Anchao, the chief designer of Chang'e-5.

Yang Anchao, led by Professor Lu, walked towards Wang Donglai.

"Hello, Academician Yang!"

Wang Donglai said hello proactively.

"Well, I heard your name from Zheng Hua many times. I didn't expect that Tangdu Jiaotong University would be so lucky to recruit you. I really found a treasure."

"This time, I brought you here because I want to borrow your mathematical skills to help us solve the lidar problem."

"How is it? Do you have confidence?"

Although Yang Anchao appeared friendly, he spoke very directly without any mince-and-thrust. He stated his purpose in just two sentences.

Wang Donglai didn't care, nodded, and said confidently: "I have confidence!"

"Okay, as long as you are confident, then come with me. I will tell you the specific information about this project so that you can have an understanding. By the way, I will tell you about your mission."

With that said, Yang Anchao walked into the office, followed closely by Wang Donglai.
