Chapter 1583 Artillery Reconnaissance Radar
"How are you doing these days? Are you used to the living here? How's the food? Is the food in the cafeteria to your liking?"

The factory director quietly walked behind someone and looked at Chai Yiyuan who was holding a pencil and manually composing a drawing in CAD. When he stopped writing, he asked.

Chai Yiyuan was drawing with great enthusiasm, but he never expected that the factory director suddenly jumped out from behind him. He was startled and turned around quickly, putting the ruler and pen in his hand on the easel.

"Director Li?"

Chai Yiyuan turned sideways to allow the easel behind him to display more space.

The drawing I just worked on was about the control panel. Although there was no computer graphics in the days, mechanical drawings were drawn one stroke at a time.

"Well drawn, very clear at a glance. This is the version you designed, right? As expected of someone who has worked in the military industry, the design is very rigorous~!"

The control panel was the first problem that the research team had to solve. Li Feng went to the next room and looked at other people's designs. It can be said that each design had its own advantages.

Chai Yiyuan came from the radar factory and had his own ideas about the control panel. However, this idea was very much in line with the characteristics of the era and looked very Big Brother-like.

"Thank you, Secretary Li. The design you proposed is not difficult. There are not many control buttons. It's just that the digital instrument is a bit difficult. It would be safer to use a mechanical instrument and add an electrical instrument."

"Mechanical instruments have limited accuracy, but they are simple and easy to maintain. Electrical instruments are complex but highly accurate. The combination of the two makes it less likely to make mistakes~!"

Chai Yiyuan looked at his own design drawings and made some upgrades based on Director Li's request. The idea of ​​military workers is to keep enough backups.

"It's okay. I don't understand technology, so I won't interfere with your ideas. When the time comes, we'll have to discuss it. Whoever has the better plan will get it!"

Li Feng took out a cigarette, tapped it with his fingers, and motioned Chai Yiyuan to take one. Drawing is a very boring job, and because of this, it is very demanding on one's character. Occasionally, when one has no inspiration, one has to rely on a cigarette to keep going.

"By the way, I wanted to ask you just now, are you used to the food and accommodation?"

The two men walked to the trash can in the corner. Li Feng lit a cigarette and saw that there were already quite a few discarded drawings in the trash can. These would have to be burned by someone later.

"It's all fine with me. I'm not picky about food, as long as I'm full, the factory has made good arrangements, we just need people to come over~!"

Chai Yiyuan smiled reservedly. He was very content. The conditions in the factory could be said to be the best. If he was picky, it would be a bit tactless.

"As for home, let's call and ask if my wife and children will come over, or what?"

"My wife will come over when the time comes, but my child won't. He will take the high school entrance exam soon, and I don't want him to be distracted. After he finishes the exam, if his grades are good, I will take him over~!"

Chai Yiyuan doesn't value Beijing as much as others do. Everyone in the group comes from a different place. Factory 720 is in Jinling, and its nickname is Huijing. Huijing is also Beijing, and the education level is not low.

Li Feng nodded. As long as his wife came over, it would be fine. If she was willing to come, it would be like a new employee bringing his own water cup to work. Everything would be settled.

"I only know some of the answers to some of the questions by reading books, but reading books is not as convenient as communicating with professionals. I want to discuss some technical issues with you. Do you think it's convenient? About radar~!"

Director Li, who didn't understand technology, started discussing technology with others again, but this time the content was more sensitive. When Chai Yiyuan heard the director talking about his old employer, he looked puzzled. Although he came from there, confidentiality didn't mean he didn't need to keep it secret just because he changed factories.

If Li Feng was not the factory director, Chai Yiyuan might not be willing to talk more about the work there.

"I won't make it difficult for you. You don't have to answer the questions you can't answer. That is, the working principle of radar is that the electromagnetic waves emitted by the device are reflected by the target and then intercepted by the antenna, and then the target is displayed on the screen?"

Li Feng raised his eyebrows. He saw the embarrassment on Chai Yiyuan's face, but this thing was very important to him and also to the artillery unit.

Seeing that the questions Li Feng asked were very basic, Chai Yiyuan was slightly relieved. These theoretical knowledge were not confidential, and there would be no problem in normal technical exchanges.

"Yes, we can lock onto the target based on its reflected waves. Director Li, does our factory also have research in this area?"

"No, it was only after you came that I came up with an idea. I feel that this idea has a lot to do with artillery. It can effectively improve the accuracy of artillery shooting and its counterattack capability~!"

Li Feng flicked the ash off his cigarette, walked to the blank easel next to him, picked up a pencil, and began to draw on it hastily.

After the artillery pieces were set up on the two hills on the left and right, the artillery on the left hill fired first. He casually drew an arc in the sky as the trajectory of the artillery shell. It was not until the right side, near the hill, that Li Feng drew the shape of the artillery shell warhead.

With just a few strokes, a simulated battlefield situation appeared on the drawing. Chai Yiyuan, who was standing by, had no idea what potential connection there was between the picture drawn by Li Feng and the radar mentioned above.

"This is the warhead of a cannonball. The speed of the warhead after it leaves the barrel is about 800-1000 meters per second. Assuming a range of 20 kilometers, the warhead should theoretically stay in the air for more than seconds. Let's take seconds to calculate. Can the radar detect this warhead~!"

"If we can detect the approach of a warhead through electromagnetic wave reflection, can we infer the launch position of the enemy's artillery based on the trajectory of the warhead?"

Li Feng used the pencil in his hand to draw a circle on the left side of the hill, and then drew a big question mark next to the circle.

The radar industry, at present, should be similar to bulletproof vests, both of which are highly confidential in the country. Li Feng has no way to directly ask the other party whether the country has started research on artillery reconnaissance radar. He can only complete the inquiry in a disguised way through this method.

Chai Yiyuan looked at the drawings drawn by Li Feng and couldn't help frowning. If Director Li was thinking in this way, this radar seemed to have some relationship with the Red Star Factory.

Chai Yiyuan's index finger gently stroked from the hill on the left to the 20-kilometer arc in the sky. Finally, his finger stopped on the warhead that was about to land, as if he had simulated the warhead that was still rotating in his mind.

"Director, do you really not understand technology?"

Chai Yiyuan was a little unsure. The function of radar was to detect the existence of objects in the sky or on the sea. Li Feng's idea was to just change the working object from fighter planes and warships to the warheads fired from artillery shells.

"I don't understand technology, but based on the trajectory of the ballistic missile, it shouldn't be difficult to figure out the enemy's artillery position. I know the role of radar is to intercept the position of aircraft. Now, I want to narrow the target down a bit, not necessarily just aircraft, but just targets the size of artillery shells. Is it possible to achieve this? This should be of some use for the timely counterattack of the artillery, or self-defense, right?"

"Director Li, if, if it is realized, what are you going to call it?"

"Artillery reconnaissance radar~!"
