Chapter 168 Effects of Integrated Radar Communication
There are many types of Huaxia Research Institute.

The most famous ones are: the Academy of Sciences, the Academy of Engineering, and the Academy of Social Sciences.

A study of science and technology.

A study of engineering technology.

A study of Philosophical Economics.

Not affiliated with each other, each researches its own.

Among them, the Academy of Sciences and the Academy of Engineering are collectively referred to as the 'two academies', with thousands of top researchers in the Chinese scientific community, also known as the cradle of 'academicians'.

Two in the afternoon.

Professor Xu came to the Engineering Institute with a thermos cup in his arms, riding the windy red flag, amidst the roar of the plane engine.

The armed old man, who had been waiting for a long time, secretly had some doubts when he saw such a grandeur. If he was raised two more levels, he might not have to take a plane next time we meet.

"Grandpa, I have sent your special car to the Weibei Test Site."

"At my level, how can I sit in a car of this specification, and besides, I can't afford it."

"The Hongqi car has applied for the official car standard. The provincial chairman and above can be equipped with a bulletproof version of the red flag. In addition, according to the honor and meritorious deeds, the car payment can be deducted. You just meet it."

"Really?"

"I'm talking, can there be a lie?"

Xu Fei chatted with the armed old man, and led by the guards to the Department of Information and Electronic Engineering.

In fact, the radar communication integration project should have been handed over to the Academy of Sciences, after all, it mainly studies technology.

However, the Academy of Engineering was newly established, and the higher-level departments paid more attention to it. In the field of information electronics, including the field of machinery and transportation involved in radar, there are more talents here.

After a while, walk into the information center.

The room, which was comparable to a basketball stadium, was filled with all kinds of people.

From the front to the back, the hair color changes from white to gray.

From the inside to the outside, the attire changed from a white coat to a fully armed green suit.

On the rostrum, in a square vessel shaped like bulletproof glass, there were two integrated circuit boards that were pitch black.

The left side is exquisite in workmanship, the size of a matchbox.

The right side is slightly rough, and the whole is like a wallet.

Undoubtedly, the former is the 'radar module part' left by Strauss, and the latter is the 'imitation' made by the researcher.

There is also a set of switching devices with various wires wrapped around it, and a mini-radar, which seems to be used to test the performance of both.

In fact, the parts disassembled from the base module can also be used as long as they are used correctly and within a radius of 50 kilometers from the base.

Such as supercapacitors.

At the beginning, it was loaded into the big red flag, and the car was deliberately driven 100 kilometers away from Huangnigang, but it turned out to be no problem at all.

For example, when Mr. Lan goes on a trip, the accompanying SEALs can get the "Leopard Commando Arms Set" through Zhang Shiren, even if he is 1000 kilometers away, there is no problem.

But the control chip of the radar module is different from the two.

It is a highly integrated system that must be within 50 kilometers of the core of the base and obtain technological support before it can be activated.

In other words, the system is connected to the minimap.

If it is easily imitated, it is estimated that one's own camp can manufacture the core of the base.

Xu Fei thought about it, put down the thermos, looked around the audience, called out the translucent page, and decided to start blowing.

But out of the corner of his eyes, he saw blackboards filled with various formulas on both sides, and then subconsciously turned around to look at the big blackboard behind him...

1. The Doppler effect of mechanical waves: f'=f*(1+v/V)/(1-u/V).

As shown.

大功率：Rmax=[(4π)2SminPtGAeσ]1/4(Pr=Smin)=[(4π)3SminPtG2λ2σ]1/4(G=λ24πAe)=[4πλ2SminPtAe2σ]1/4(G=λ24πAe)
As shown.

2. Amplitude modulated continuous wave signal...

Amplitude modulated pulse signal...

As shown.

3. Frequency Modulation Linear Frequency Modulation (LFM, Chirp).

As shown.

3-1, frequency agility.

As shown.

3-2, Phase modulation.

As shown.

4. High-power electromagnetic oscillation generation and modulation are completed at the same time.

As shown.

5. Output power...

11. Rectangular amplitude modulation, working ratio 0.01%~1%...

'My mother, what the hell are these symbols? '

Xu Fei was stunned for a moment, and quickly dragged the translucent page, but couldn't find a matching profile.

Yup!

Strauss has said all that needs to be said, so why am I here?

Can you explain the formula on the blackboard?

But there are no junior high school textbooks or high school textbooks.

Besides, how to pronounce these letters?

Xu Fei turned around and picked up the thermos, "Well, grandparents, I'm sorry, I went to the wrong house."

Everyone: "..."

"Let's see you later, and welcome everyone to visit Wong Nai Kong."

After finishing speaking, he stepped off the rostrum and rushed out of the house.

Seeing this, the armed old man quickly stopped him, "Don't tell me, do you understand?"

"I understand, but I don't understand the calculation formula."

"..."

"I mean, I can hook up the modules, but let me explain what signal stability, what spectral purity, what frequency the actual transmit signal is, aren't you embarrassing a high school student?"

As Xu Fei spoke, he suddenly became confident.

Yes, I am a high school student.

I know a hammer.

The armed old man must know that this guy doesn't understand, "You connect the modules first."

"no problem."

Xu Fei walked back to the rostrum, picked up the module left by Strauss, and pulled out many lines and card slots with pins from the switching device.

In fact, he secretly called out the translucent page, looked at the core of the main base that was left in the hotel suite and was looked after by 10 engineers, and chose to activate the dismantled radar.

Then, take back the core of the main base again.

This is because, to activate a base unit, a base core must be dropped.

Now that it is activated, carry the base core with you, as long as the base unit is within 50 kilometers of itself, it can be used normally.

Moreover, the core of the main base is different from the huge core of the secondary base.

As long as the production line is stripped away, the whole becomes smaller.

Look at the introduction, this is convenient for the commander to hide easily after the defeat.

Of course, when the core of the main base comes to the capital, the base units within the Huangnigang area will definitely lose their effect.

But currently there are three secondary base cores, one is in Seoul, and the other two have not been deployed.

Therefore, when Xu Fei came, he left the second one in Huangnigang and authorized engineers to take care of it, so as to prevent various enterprises from suspending production.

at the same time.

With the light of the integrated circuit board indicator light, a picture consisting of 'circles' emerged on the projection device on the left.

Since there is no map, the current radar module only presents the most primitive 'visual effects'.

However, it still marked the number of people in the venue, how many tables there were, and the length, width, and height of the venue.

Xu Fei looked left and right, started the computer that came with the radar module, and connected another projection device.

2 minute later.

The second curtain outlines a 3D model.

Including people's faces, figures, clothing edges and corners, and raised walls in the venue...

Then, with a millimeter-level error, it will continue to enrich all of this.

Unfortunately, all gray and white, no other colors.

And because the radar is indoors, the power is low, so it cannot penetrate the building, and can only present everything in the venue.

But these functions, in this day and age, are still terrifying and scary.

If it is applied on the battlefield, what kind of thermal imager is needed?
The armed old man said: "Is there any news?"

"there must be."

Xu Fei started the computer that came with the second radar module, and then connected the third projection device.

soon.

A set of pictures composed of four angles: horizontal, front, rear, and bird's-eye view, appeared in front of everyone.

And there is a ball in the middle that can adjust the angle, roll it at will, and even pull it into the camera, and see a certain academician wipe his glasses...

"My God, this kind of radar, except that it has no color, almost achieves high-definition camera level."

"No wonder Mr. Zhang said that this is not something that should appear in this era."

"No, its transmission and reception frequency is too high, and the performance of the computer...I suspect it surpasses the new generation of Galaxy."

"Is overseas technology so advanced?"

The discussion gradually disappeared, and many academicians, like Weibei researchers, cheered up after worrying and decided to catch up.

After all, if one's own camp obtains this level of radar, it means that it is almost invincible in the same field.

With such a high start, why are you afraid of going abroad?

Xu Fei was busy, thought carefully, dragged the big blackboard, and picked up the chalk, "I remember the TEP database, which once decrypted such a piece of information, saying that the integration of radar and communication is only the most elementary project, and the next stage should use photon characteristics. Constitutes optical communication and optical detection."

"In other words, the integration of second-generation radar communication belongs to the application of 'visible light' technology."

"It's just that electromagnetic waves are as fast as light, and both will be blocked by smog and thick clouds. I don't understand the advantages for the time being."

"The third-generation radar communication integration, also known as the sensory communication system, belongs to the quantum level, just like today's 3D modeling. At that time, it can directly present a color picture, and it can even be divided into dynamic and predictive dynamics. That is to say, I can know what action you are going to do next and make a response in advance."

"Of course, the third-generation technology is currently at the theoretical level, and there is no relevant technical support."

After Xu Fei finished speaking, he looked at an old man who was talking in a low voice with the old man who looked like the person in charge of the engineering academy.

"That's about it. Well, can I get into the school? I don't want to be a graduate student, but I can get an undergraduate degree. As you can see, I have a strong practical ability."

Hearing this, the latter chatted with the armed old man again, and seemed to understand the meaning of the words, "Boy Xu, this is not a school. If you want to go to university, our department can help you apply for MIT. One quota."

"Forget it, let's leave the places to the seniors, I will go to study abroad with my ability!"
