Cheng Yuan and Chen Chao originally came to Zhao Zhongyao's office with great interest, thinking that as long as Zhao Zhongyao read the design drawings of the two of them, they would definitely praise them! But after listening to Zhao Zhongyao's words, they were a little unhappy.

"The radar I'm talking about isn't what yours looks like! You can only be regarded as a new-style communication radio station! Can this also be called an air defense radar?" Zhao Zhongyao looked at Cheng Yuan and Chen Chao angrily and said.

"Yes, you said that we designed this not an air defense radar, then what do you say the air defense radar looks like. This is a new type of equipment, and there is no information, and there are no samples, and it is not what we design, but what it is!"

Cheng Yuan listened to Zhao Zhongyao's words, and he immediately pulled his face down.

"Yes, Director Zhao, this is strange, the air defense radar is a brand new equipment, we have never seen it, how can you say that the air defense radar we designed does not look like a radar! Then what do you say the radar should 'look like'!"

Chen Chao was also very unhappy, and he also looked at Zhao Zhongyao with an angry face.

"That's right, the air defense radar is a new type of equipment, but it must also be designed according to the actual situation! The defense radar is used to track high-altitude reconnaissance planes. It is used to detect such high-altitude metal objects. But how can you track high-altitude reconnaissance planes with such a thing you designed!"

Of course, Zhao Zhongyao knows the role of air defense radar very well, and when he saw this thing designed by Cheng Yuan and Chen Chao, he felt funny, they didn't know what radar was at all!

"Okay, our design is not good, then your Director Zhao is good at designing! Don't you even have this kind of bad design! What qualifications do you have to say that our design is not good!"

Cheng Yuan has a big temper, and after listening to Zhao Zhongyao's words, he immediately became angry.

"Yes, Director Zhao, do you look down on the two of us! You don't have any designs for anything yourself. Just shoot the things that the two of us worked so hard to design, don't you respect the hard work of the two of us!"

Chen Chao saw that Cheng Yuan was on fire, of course he was not polite, and immediately fired at Zhao Zhongyao.

"Haha, well, since you're not convinced, let you see. What does a real air defense radar look like?"

Zhao Zhongyao didn't want to make these two guys ugly! But they were actually angry with themselves, so what was he polite to them!

Zhao Zhongyao said as he put the four different air defense radar drawings designed by Cheng Yuan and Chen Chao on the sofa on the side, picked up the air defense radar drawings he designed on the desk, and put them in front of Cheng Yuan and Chen Chao.

When the two looked at the air defense radar drawings designed by Zhao Zhongyao, they were dumbfounded. They saw a piece of equipment that they had never seen before, a device with a semi-spherical antenna, similar to a radio station, with a circular shape and a display or something.

"Is this the anti-aircraft radar you designed?"

Cheng Yuan looked at the equipment designed by Zhao Zhongyao, which looked very special. Asked curiously.

"Yes! This is the air defense radar I designed, how about it, is it much more advanced than yours!" Zhao Zhongyao said very confidently.

"What's wrong with the fact that it looks advanced, maybe it's not as useful as the air defense radar we designed!" Chen Chao was also a little surprised when he saw the air defense radar designed by Zhao Zhongyao! Because he had never seen this kind of semi-circular spherical antenna!

But how could he be willing to admit defeat in front of Zhao Zhongyao! So he was unconvinced and defended himself in front of Zhao Zhongyao.

"I know you're not convinced, so I'll explain it to you!" Zhao Zhongyao said. While putting his drawings on his desk again.

"Radar is a piece of equipment used to track and detect enemy aircraft, and it works with electromagnetic waves. The plane is in the middle of the sky. It was just a metal object, although the size of the plane was more than ten meters long.

But compared to the vast sky, these objects of more than ten meters are just a small black dot from the ground!

To detect such a small target, it is necessary to make only the antenna of the air defense radar. When emitting electromagnetic wave signals, it can cover a large area of the sky!

The kind of simple equipment you designed can only detect a beam of electromagnetic waves, and it can only be aimed at the sky in a certain direction. It's impossible to catch a small target in the sky!

And the spherical antenna I designed is different, on top of this antenna I designed. There are a lot of small antennas. Each small antenna can emit a beam of electromagnetic waves.

And this antenna of mine can also rotate. In this way, when the air defense radar I designed is working, it can cover a large area of the sky with electromagnetic wave signals, and as long as a certain suspicious enemy plane flies to the target area that the air defense radar I designed is constantly scanning, it will be able to detect them on the radar display very quickly.

And the air defense radar you designed can only emit one beam of electromagnetic waves, and can only target someone in one target area, so you say, do you have a target for capturing the target!

Let me give you another simple example. You will understand better.

The air defense radar I designed was like a big net in the sky. And the air defense radar you designed is nothing more than a birdcage in the sky. You say, is it easier for you to catch the birds with this birdcage, or is it easier to catch the birds with my big net?"

Zhao Zhongyao's words can be said to be vivid and simple to understand, after saying it, Cheng Yuan and Chen Chao were stunned, the two of them were speechless, and they couldn't say a word.

"Cheng Yuan, Chen Chao, this kind of air defense radar you designed is actually similar to using human eyes to look at the target and find the target! The two antenna-like air defense radars you designed are the same as your two eyes! You say, what's the use of your design, it's better for you to stand on the roof of the building and keep looking at the direction in which the enemy plane might fly!"

Zhao Zhongyao saw that these two guys didn't speak, so he took advantage of the victory to chase after them and played a trick on the two of them again.

"Zhao--Director Zhao, in this way, the air defense radar you designed is really very advanced, and the one we designed is not very good. Cheng Yuan was already stammering and didn't know what to say.

"Hmph, there are some things that are useless just by saying it. Director Zhao, don't boast about the air defense radar you designed like a flower, is this just a drawing! Whether it is useful or not, I am afraid that it will only count if it is developed!" Although Chen Chao was also surprised in his heart, he was unwilling to admit defeat! (To be continued......
