After hearing Yan Mingcheng's words, Zhao Zhongyao laughed and said: "Old Yan, are you trying to gain other people's ambition and destroy your own prestige?"

Yan Mingcheng quickly smiled and said: "Yes, I'm just telling the truth. Are their stealth missiles awesome? Damn it, they hit our mushroom island, and we didn't even know it!"

"Lao Yan, don't worry, no matter what bullshit stealth missiles the enemy develops, I can always find a way to deal with them."

Zhao Zhongyao is very confident. He has surpassed Jonis and Wesley many times in anti-interference technology before. This time, he also feels that he can surpass them.

"Zhongyao, what do you think? Will you make a fuss about the radar again this time?" Yan Mingcheng thought of how Zhao Zhongyao had made a fuss about the radar several times before and defeated the enemy.

, this time, he wondered if Zhao Zhongyao wanted to make some improvements on the radar again!

"Of course it is. Radar is the eye of the missile. Without radar, the missile is just a pile of scrap metal. If the enemy has developed a stealth missile, then we must develop a new radar that can decipher the anti-jamming signal on the enemy's stealth missile."

Zhao Zhongyao feels that this time it is not just about improving the radar, but it seems that a new type of radar will be developed!

"What, you want to develop a new type of radar, is this necessary? You can just improve the original radar." When Yan Mingcheng heard Zhao Zhongyao say that he wanted to develop a new type of radar, he still couldn't figure it out!

"It's okay to improve it, but in this case, it's better to develop a new one." Zhao Zhongyao looked at Yan Mingcheng and said.

"Why, last time, didn't you just install an 'electronic cutter' on the radar and be done with it? Why, this time you are going to develop a new radar! You won't use an 'electronic cutter' again.

Knife'!"

Yan Mingcheng felt that it would be troublesome to develop a new radar. It would be easier to improve the original radar. He felt like last time, just add an "electronic cutter" to the radar and that would be it!

"Old Yan! Do you think that 'electronic cutter' is a '******!' It can open any kind of 'lock'! This time the enemy's 'lock' is not ordinary. I still use the previous one.

I'm afraid the 'key' is of no use at all."

During this period of time, Zhao Zhongyao had already thought about how to deal with the enemy's stealth missiles. He knew that in order to deal with the enemy's stealth missiles, a new high-power radar must be developed. The original radar was not powerful enough.

.It doesn’t work at all. It can only deal with ordinary missiles. I’m afraid it can’t deal with the new stealth missiles developed by the enemy. This time they can successfully launch it, which means that their previous air defense radar is time to be updated.

It's time.

"Oh! Is it so powerful? How on earth did the stealth missile developed by the enemy become invisible this time? Wasn't it like before that a radio anti-jamming device was installed on the drone?"

When Yan Mingcheng thought about the issue of stealth, he naturally thought of the anti-jamming equipment installed on the enemy's drones before. He thought that the stealth missile developed by the enemy this time might be the same as the one installed on the drone last time.

It’s the same thing as the anti-interference equipment installed above!

"Haha! This time, they were able to become invisible, which is much better than last time." Zhao Zhongyao looked at Yan Mingcheng and said with a smile.

After hearing this, Yan Mingcheng looked at Zhao Zhongyao with wide eyes and said: "Then what is the difference between the stealth missile they developed this time and the previous drones!"

"On the previous drone, Jonis and Wesley installed an anti-jamming device on it.

You have also seen this anti-interference device. It is just a small rectangular iron box. In fact, it is a radio transmitting device that simulates radar waves. When used on an airplane, this device can be used to emit some radio waves. These

Radio waves and radar emit radio waves at the same frequency. This will cause the radar to regard this false signal as a signal that bounces back when the radar wave hits the drone.

At this time, the drone may have flown beyond the radar's scanning range. The radar thought that the drone was within the radar's scanning range. The anti-jamming equipment used by the enemy's drone only allows the radar to

Unable to determine the specific location of a drone in the sky does not mean that the drone cannot be detected by radar.

Air defense radar can detect drones, but there will be deviations when determining the location of the drone. In other words, the anti-jamming equipment on the drone only allows our air defense radar to accurately measure the target position in the sky.

The speed drops, rather than the target being unable to be found.

But this time the stealth missile developed by Jonis and Wesley is different. This thing can completely block the radar waves of the air defense radar, making the radar completely unable to 'perceive' the existence of the stealth missile.

In this way, our radar becomes a decoration for stealth missiles, and has no certain function. It is equivalent to saying that as soon as other people's missiles fly in, our air defense radar's eyes are blinded, and the radar

Even if there are many 'eyes', I can't see a single stealth missile!"

Zhao Zhongyao is indeed a military genius. Regarding the enemy's stealth missile attack this time, he quickly understood how it all happened and what was the root cause of it all.

It's just that Yan Mingcheng is not a military expert. He was still a little confused after hearing Zhao Zhongyao's explanation of the difference between stealth missiles and drones.

"Zhongyao, you said that the stealth missile developed by the enemy can completely block the signal of our air defense radar this time. So what advanced instruments did they install on the stealth missile? It can actually do this!

Yan Mingcheng couldn't understand what Zhao Zhongyao said, so he asked again.

"I don't know exactly what advanced instruments Jonnis and Wesley have installed on their stealth missiles. After all, we can't see the missiles they launch now, so we don't know what advanced equipment they have on their missiles.

Where is the instrument!

Last time, the enemy launched a drone. At least we were able to find some anti-jamming equipment from the wreckage of the drone.

But this time, they launched a missile. The missile completely self-destructed after attacking the target. Even on Mushroom Island, where the missile attacked the target, you could not see the appearance of their stealth missile. At most, it could

Just pick up a few pieces of shrapnel.

This is also meaningless. It is impossible for us to see from a few pieces of shrapnel what advanced instruments they have installed on the missile."

"Zhongyao, what you are saying is that we have no idea how the stealth missiles developed by others can become 'invisible'. Then how can we deal with them? You were so confident just now, I don't understand your

That’s where confidence comes from.”

When Yan Mingcheng heard Zhao Zhongyao say that he didn't know how the invisible missiles developed by Jonis and Wesley could become invisible, he was very surprised. He didn't understand that Zhao Zhongyao didn't know how the missiles were made invisible.

It's completely invisible, so how can you deal with others?

"Old Yan. Although I don't know how the enemy's stealth missiles become invisible. But I am certain that they must have installed something powerful that blocks radio signals on the missiles. This kind of thing can block the radar.

The waves are blocked, or absorbed. Our air defense radar can only transmit signals to their missiles, but cannot receive any signals. In this case, it is equivalent to our air defense radar not detecting anything. Because there is

This situation is exactly the same as the normal working state of the radar. Usually the radar will also emit radio waves into the air when no target is found. However, these radio waves fly into the universe and will naturally not come back.

.So, our radar can’t find anything. You have to know that the working principle of radar is to transmit a signal and then receive the reflected signal. If the reflected signal can be received, it means that the radar has found the target, and vice versa. If it cannot receive the

If the reflected signal is detected, it means that the radar has not found the target. The enemy's stealth missiles can completely block the radio waves of our air defense radar, so naturally our radar can't detect anything."

Zhao Zhongyao explained in detail again. Yan Mingcheng finally understood.

"Ah, so the stealth missile developed by the enemy this time is indeed very powerful, and we have no good way to deal with it." When Yan Mingcheng heard Zhao Zhongyao's explanation, he was a little discouraged.

"No, no matter how advanced the enemy's missile is. But I think the biggest difference between this missile and ordinary missiles is that it can completely shield the radar signal.

On the surface, the enemy's stealth missiles are indeed very powerful. But the opposite can also be said. It's not that the enemy's stealth missiles are powerful, but that our air defense radar is not very good. It's not very powerful. If our air defense

Radar is so powerful, can it still detect the enemy's stealth missiles and make them invisible?"

Zhao Zhongyao knows that in fact, it is difficult to completely shield radio signals. It would be good if most of them can be shielded. He believes that the air defense radar he developed is already relatively advanced.

The reason why such an advanced radar still fails to detect the enemy's stealth missile is mainly because the power of this radar is too small. If the power is too small, the radio waves emitted are not strong. This allows the radio signal shielding device on the stealth missile to shield it.

After being detected, only very few radio signals can be reflected back. The reflected radio signals are too weak to be detected by the radar itself. This is the real reason why the ground air defense radar did not detect the stealth missile.

If you want to detect stealth missiles, you can only develop a high-power air defense radar to make the radar's transmission signal very strong. In this way, even if the stealth missiles are shielded, a large amount of signals will still be reflected back to the radar.

In fact, radio signals are just like light. It is obviously impossible to completely shield the light waves.

This is one reason why humans still cannot develop an invisibility cloak. Because light will be reflected when it hits any object. There is no object in the world that does not reflect light. As long as there is reflected light, it will be visible to human eyes.

.

To achieve true invisibility, the object must not reflect light. This is a very abnormal phenomenon. It is almost impossible to develop an object that does not reflect light on earth.

How to achieve true "invisibility". There is only one way, which is to make the light not reflect back when passing an object, but go around the object. This is what we usually call the light bending phenomenon.

Whether light can really bend is simply impossible in Newton's classical physics. Only in Einstein's Theory of Relativity can some theoretical basis be found.

In order for light to bend, the object must have a huge gravitational force. Only a huge gravitational force will cause light to bend.

This huge gravitational force is beyond the reach of human beings. Only the gravitational force generated by huge objects such as celestial bodies can bend the light passing through them.

For example, the sun can bend the light from stars emitted from distant interstellar space.

Of course, this phenomenon is not easy to see. It can only be detected with special instruments during a total solar eclipse.

Einstein's great prediction that "gravity can bend light" was detected by scientists through a total solar eclipse.

But even celestial bodies, not all celestial bodies can bend light! Only huge stars like the sun and some special dense celestial bodies with huge gravity can possess such 'divine power'.

Planets like the Earth do not yet have this ability! Of course, this is only a relative term. Perhaps the Earth can also bend light, but the bending rate is so small that humans cannot observe it. It is the same as no bending.

.

Although stars as big as the sun can bend light and can be detected by humans, the sun can only bend light slightly, which is not obvious at all.

Highly dense celestial bodies such as neutron stars can bend light so much that the light from the neutron star is emitted in the form of parabolas, instead of being emitted directly like the light from the sun.

The densest celestial body in the universe, the black hole, which is denser than a neutron star, can not only bend light, but also bend the light into a circle. In other words, if a beam of light passes through the black hole, then this beam of light will be
