Chapter 1174 There are so many people at the airport
Li Wenjun waved his hand at him, motioning for him to get out of the way.
Then I adjusted the angle of the "pot lid".
He waved to Dong Qingjun.
Dong Qingjun whistled into the microphone.
The bird was so frightened that it flew away.
Tao Guangming's eyes widened: "Really?"
Dong Qingjun nodded: "Ang."
Tao Guangming still couldn't believe it and muttered: "The bird was not that far away just now. Without this thing, your whistle can scare the bird away."
Dong Qingjun said: "The current effective range is one kilometer. Director Li requires us to reach more than three kilometers."
Tao Guangming sneered: "Why don't I believe it? It's still one kilometer."
Dong Qingjun adjusted his angle to face the mountain, increased his energy, and stretched out his hand toward Tao Guangming: "Come on, come on, it's about a kilometer from the back mountain to here."
Tao Guangming said to the microphone: "Get out!"
Then a flock of birds on the mountain started and scattered.
Tao Guangming looked blank, and then gave a thumbs-up to the directors of several research institutes: "You are great."
Then the directors of those research institutes rolled their eyes: Damn, you bastard, just one sentence has caused us to lose a lot of hair. If we hadn't scared you just now, we would really want to strangle you to death right now.
-----
Tao Guangming took that thing and ran to the airport to try it out for a day.
The effect is really good. Five or six of them are installed in an airport and they play sharp sounds. No birds will fly in at least 500 meters in the sky outside the airport wall.
Tao Guangming has been running around in the sun every day for two consecutive months. He has become tanned and numb, almost the same color as Xiao Hei, and has also lost a lot of weight.
Li Wenjun laughed at him and returned to ten years ago overnight.
------
In fact, the airport built by Li Wenjun also has a secondary radar, which is just a simple radar transmitter and receiver, commonly known as an interrogation machine. It has no imaging and positioning function.
This time Yang Shouzhuo was very tight-lipped. Anyway, Li Wenjun would not be allowed to fly again unless he completed the short-range primary air traffic control radar.
Then, Li Wenjun handed over this task to the walkie-talkie factory. The electronic equipment factory and the machinery factory cooperated.
Zheng Yuehua, the director of the walkie-talkie factory, was confused when he received this task. He said to Li Wenjun with a sad face: "We who make walkie-talkies are really no match for radar."
Can't you just treat us like shit?
Let us make walkie-talkies with peace of mind and make a little money, even if we are ranked last in the "Wenjun Industrial" every year.
Li Wenjun comforted him: "Actually, they are all radio waves, transmitting and receiving. They are just larger and farther away, so don't be afraid."
Zheng Yuehua knew that he could not shrink back.
Back then, with the help of Li Wenjun, he chased the stewardess.
Now my father-in-law has been promoted. If he can't do this, the director of the walkie-talkie factory will have to be replaced.
This time he asked his wife to obtain the technical parameters of surveillance radars of several major airports, and then studied them behind closed doors with the technicians at the factory.
Thinking about it carefully, hey, this thing is not as demanding as a mobile phone base station.
If the distance is a little further than 100 nautical miles, then get a radio frequency with high power and low decay!
You can do it, don’t be afraid.
Then it took half a month for Ding Ding Bang to make the first version.
Li Wenjun attached great importance to it and came to the walkie-talkie factory to have a look.
Then Zheng Yuehua turned on the radar very confidently.
Li Wenjun looked at it for thirty seconds and said, "No, do it again."
Zheng Yuehua was very unconvinced: "No way."
Li Wenjun said: "You can't even use this radar. The airport is equipped with one, and you need more than a dozen to fully cover it. Why did I call the machinery factory? Because you want to give him a task and ask them to help you solve the mechanical problem.
.”
Zheng Yuehua fell silent.
The picture he got was flat and would not move.
He had never seen the radar operating. He had no idea what Li Wenjun meant by turning in circles.
Is it up and down, or left and right?
Is it like an electric fan shaking its head, or like a wheel spinning?
Then he salivated and begged his father-in-law to let him observe the airport radar.
My father-in-law found an acquaintance and took him in to have a look.
Zheng Yuehua took one look and understood that it turned out to be a 360-degree circle.
No wonder Li Wenjun said that one can cover all directions.
Then the walkie-talkie factory spent a month to make the second version.
Li Wenjun said to put it on and try it.
He requested that radar monitoring be used in conjunction with bird-catching equipment, drones, and new desktop computer prototypes made by the computer factory. By the way, he would test the computer prototype.
When turning on the bird-catching equipment, use radar to monitor birds over the airport, large drones and kites that are specially flown.
By the way, I also checked the performance of the drone.
After the radar was installed, Li Wenjun asked Tao Guangming and Zheng Yuehua to go together for the detection task.
Tao Guangming thinks this life is quite interesting.
You can play with drones, radar, and computers.
After hearing this, Dong Qingjun dropped what he was doing and followed Tao Guangming.
Everyone was used to Dong Qingjun's lack of organization and discipline, and no one stopped him.
He will finish his work in the end anyway, so why make yourself angry by nagging him.
Tao Guangming and Zheng Yuehua sat in the control tower, and then Dong Qingjun went outside to fly drones and large kites.
The 6m wide and 3m high radar antenna with a plane distance of 3.8 meters from front to back has been turned on remotely. It faces the sky of the airport at an elevation of 1.5 degrees and rotates at a speed of one revolution per second.
Tao Guangming turned on the monitor, and then he and Zheng Yuehua leaned back in fear.
Because the screen is full of stuff.
The distances vary from far to near. One or two kilometers are as close as possible, and dozens of kilometers are far away.
If it's something three kilometers away, no matter how much it is, they won't be surprised.
Maybe there was a plane passing by.
What's within one kilometer is obviously over the airport.
According to what is displayed on the radar, the sky above the airport is now occupied.
Tao Guangming walked to the floor-to-ceiling glass with a telescope and looked carefully, but found nothing.
Damn it, am I an old lady?
He walked back and stared at the screen.
Although those things are no bigger than a fingernail, their shapes are very vague. But if you look closely, some of them look like old ladies, and some of them look like the face of a devil. Anyway, the more you look at them, the more scary they become.
A chill ran up from my tailbone, along my spine, and straight to my forehead.
Tao Guangming pointed to the monitor and asked Zheng Yuehua: "Did you see it?"
Zheng Yuehua also looked very unhappy and nodded: "Ang."
Tao Guangming: "What is this?"
Zheng Yuehua shook his head: "I don't know."
Tao Guangming asked Dong Qingjun on the walkie-talkie: "How many kites did you fly?"
Dong Qingjun: "Crazy, just give me one and I can put a few in. I'm not the Thousand-Hand Guanyin. I haven't put any in yet. This thing is too difficult to handle."
