Chapter 3479

The formula of target distance S = CT / 2, s is the target distance, t is the time from electromagnetic wave transmitting from radar to receiving target echo, C is the speed of light.

It is an important function of radar to measure the velocity of target. The Doppler principle in physics is used in radar velocity measurement.

About ten minutes later, Zhou Nan stopped his movements.

"Deputy regiment, I analyzed the areas determined by the maximum operating range, minimum operating range, maximum elevation angle, minimum elevation angle and azimuth angle range, and calculated that the radar's risk coefficient is high, and it is recommended to intercept."

Kong Feng's eyes flashed and appreciated, but his face was cold: "OK, you go out first."

Zhou Nan's heart cluttered for a moment. Why did the vice regiment let her go out? Is it her calculation error?

No, she is very confident in this area.

But deputy commander Kong's face was cold, and she didn't dare to say anything more. After a salute, she left the radar monitoring room.

As soon as she went out, Ren Yusheng came out of the small office beside her and said in a low voice, "how, deputy head Kong, is the test still qualified?"

Kong Feng's face was expressionless: "he is still young and needs more experience."

"Can he take part in some of our important tasks?"

"Barely qualified, he can come in and learn more and watch more."

"Kong's deputy regiment is so strict that he has passed the test. At least that boy has two real skills, isn't he?"

Kong Feng squinted at him: "this is just a basic test. If he comes in and stagnates, I won't be lenient outside the law."

"Yes, yes, I think the same as you."

After Zhou Nan went out, he was still worried. He wanted to practice shooting in the shooting range.

She kept in mind the instruction of the commander and did not dare to relax in physical training.

As soon as I entered the shooting range, I saw Hu Jun and Tao Peng. It's true that they didn't get together.

Zhou Nan put on the earmuff, took the gun, and went to the shooting table. The target was about 15 meters away. She adjusted the earmuff and loaded the gun with ammunition. After that, Tao Peng came up to her and hit her elbow heavily. The loaded ammunition almost slipped out.

Zhou Nan turned to look at him: "what are you doing?"

Tao Peng sneered: "what do you do?"

Zhou Nan took off the earmuff and looked at him: "you bumped into me. I'm sorry."

Tao Peng shrugged: "who saw you hit me?"

Zhou Nan glanced at his epaulet: "I saw it. You bumped into me, apologized, and ran 30 laps on the playground as punishment."

Tao Peng looked at her like a monster: "what do you say?"

Zhou Nan said coldly: "what? My rank is above you. I'm at the battalion level, and you're at the deputy battalion level. You don't have the honor to go up. You've committed more than one time. I'll punish you. Are you not satisfied or what? "

Tao Peng was so angry that his face turned to pig liver color. Hu Jun came from behind. Before a word was said, Zhou Nan gave him a cold look: "why, is commander Hu going to cover up your subordinates?"

Hu Jun:

Damn it, how can this kid be so eloquent?

At the door of the training room, Gu Yanzhi and Ren Yusheng walked in side by side. Ren Yusheng glanced at him: "Yanzhi, you are really very concerned about your old subordinates. I don't see you attach so much importance to a person."

"He's excellent, isn't he?"

"Yes, it is. It's excellent in every aspect."

"I just came by to see him, and then I left."
