527: A word to wake up the dreamer!

Wang Jianguo seemed a little surprised at the moment, because he saw Su Ming’s nonchalant expression, which is usually only shown when a person has considerable self-confidence.

After a moment of shock, Wang Jianguo said: “Xiao Ming, you should first explain your own point of view. It doesn’t matter if you say it wrong.”

Wang Jianguo still doesn’t believe in Su Ming. After all, Su Ming is a teenager. He was only in the first year of high school this year. Hearing that he has been invisible to fighters can only show that he pays more attention to the news.

But to say that you can think of a way to crack the invisible technology, this is a bit of a fantasy.

As a national senior researcher, I haven’t achieved any decent results after studying for more than two months. I can’t solve this problem with just one child, right?

Su Ming saw Wang Jianguo’s expression and knew what he was thinking, but he didn’t feel any discomfort due to it.

Wang Jianguo helped him a lot, and he is also a national senior researcher. It is already very good for someone to talk to himself so politely. Otherwise, who would discuss such a cutting-edge problem with a child?



Su Ming smiled slightly and said, “Uncle, the stealth fighter is made invisible by reducing the radar reflection surface, right?”

Wang Jianguo nodded when he heard this. There were also reports on this news. It was nothing unusual. Su Ming looked at him and nodded, and then said:

“If you want to deal with a stealth fighter, the most important thing is to be able to find it in time, so that it has nowhere to hide and can attack it, Uncle Wang, is that right?”

Wang Jianguoxin said: Isn’t this nonsense? This is what I am studying now, can you directly get to the point?

Although Wang Jianguo thought so in his heart, he smiled on his face: “Yes, but it is not a simple thing to find it in time. Its radar reflector is too small and it is easy to be overlooked.”

Su Ming smiled slightly, and then said something like this: “The radar reflector we discussed just now is only relative to a single radar. If multiple radars are used to target it at the same time, what do you think will be the result?

When facing a single radar, the stealth fighter can refract and absorb radar waves very well, but after all, there will still be radar waves escaping.

If these escaped radar waves are received by other radars, the cross section of the stealth fighter will become very large.

…For flowers…

At least it is much larger than the radar reflector of a bird, so that it will not be discovered?

This truth can be described in an ancient poem: “Looking at the side of the mountain is like a mountain with a peak.” When two people look at the same thing from different angles, the shapes they see are different.

It is like a mirror. If you face it, you can know its area intuitively, but if you stand on its side, all you see is its thickness.

.0

In this way, is the area of ​​the mirror that sees you much smaller?

Of course, if you want to talk about the sphere, then you don’t need to talk about it. The stealth fighter is not a sphere. Then it is more inappropriate to do it?

The working principle of radar is similar to this. It judges the size of this thing by transmitting radar waves and receiving the radar waves reflected by the object.

The stealth fighter has many refraction surfaces and special materials are used to minimize the radar waves that are fed back to the radar.

If a radar emits 100 units of radar waves, it may be absorbed and refracted by the stealth fighter itself.
