Technology: breaking the hegemony that monopolizes the world

The more old professor Zhou Xia thought about it, the more uncomfortable he felt, and his scalp became numb.

And Gu Qing already has the relevant content of Xuanwu Projection in front of him.

What the old professor was talking about came from a new type of radar developed by a certain institute of Daxia Guodian.

The working basis of the radar is the microwave quantum theory, and the operating environment is also relatively special, and must work at extremely cold temperatures. The performance and functions of this radar match the harsh and special working environment.

It can detect objects up to 15 million kilometers away.

This very exaggerated distance is equivalent to about forty times the straight-line distance between the moon and the blue star.

And according to the data collected by Xuanwu, this kind of radar can not help but detect unknown asteroids, and can also detect objects that are missed by other detection methods, such as some spacecraft such as stealth satellites.

The general radar works by means of radio waves. It transmits radio waves in the direction of the target through the antenna. After some radio waves are reflected by the surface material of the target object, they are received by the receiving antenna of the radar. After calculation by the system, it can be If the distance of the target is obtained, the launch and reflection frequency is high enough, and important parameters such as the direction, speed and even weight of the target object can be obtained.

It's just that this radar detection method is very weak in detecting distant targets due to the limitation of radio waves, and according to the radar detection distance formula that the maximum detection distance of the radar is proportional to the fourth root of the maximum transmission power of the radar, Under the condition that other conditions remain unchanged, if the detection distance is to be doubled, the transmission power of the radar must be increased to 16 times, or if the detection distance is to be 10 times, the radar’s The transmit power must be increased to 10,000 times the original.

Xuanwu also posted an example here very thoughtfully. The radar used for asteroid detection in the United States has an antenna with a diameter of 70 meters. The continuous transmission power in the X-band exceeds 1 megawatt, and it can only detect hundreds of thousands of kilometers. outside target.

Now, a new type of radar developed by a certain institute of Daxia Guodian Technology can detect objects tens of millions of kilometers away under theoretical conditions.

This is a bit similar to a certain radar under development of the Kyushu Science and Technology Aerospace Project

After browsing through the materials compiled by Xuanwu, Gu Qing sighed when he saw that the old professor still had a depressed and aggrieved expression like a cucumber.

If I don't solve this misunderstanding, will this professor be entangled to death?

Looking at the content of the report, Zhou Xia felt that every word of these brilliant achievements was so dazzling that his heart trembled every time he read it.

"This is a report from last year. Although they only worked out the theoretical basis and did not produce the actual object, this kind of parts require special equipment. How could they figure out the theory so quickly?

It's all my fault, I shouldn't have gone to that industry party, let alone drink, alas.

what to do?

Is it possible to let the company go to court with Charcot? This is simply, this is simply impossible!

I heard that the company is now dealing with a group of British technology companies in cross-border cases, and it simply does not have the resources and energy to deal with this situation.

How could these old friends of mine be such people?

They are obviously very honest...but this radar, I—"

"You were still designing a new generation of parts yesterday. In order to upgrade the environmental restrictions to warmer parameters, you did nothing wrong. When you were partying, you brought members of our security team with you, so you must have not leaked it. confidential."

Gu Qing's gentle voice made Professor Zhou, who was immersed in self-blame and shame, pause.

"This is the information at the Zhuhai Air Show six years ago. Daxia Electronics exhibited models of quantum radar and microwave photonic radar. Although they are all conceptual products with a sci-fi color, according to later interviews, Electronic Technology Yes, there is indeed research on this.”

Professor Zhou raised his head slowly after hearing this.

He is an old expert in this field, how big is the "gold content" of these two radars.

Quantum radar is a cutting-edge radar that uses the principle of quantum entanglement to work. By measuring the reflected photons, physical properties such as the size, shape, direction, and speed of the target can be calculated.

Although microwave photon radar still uses the old theory of electromagnetic wave reflection to work, photon technology will be added to the work to improve the key performance of the radar system such as target resolution, operating distance, and response speed.

Gu Qing saw that the old professor's eyes began to focus, and he continued: "The theoretical news about microwave quantum radar you have seen is just a new generation of technology based on this.

You are an old man engaged in research in this field. Of course, you know that radio waves are also a kind of light, which can be divided into tiny particles that cannot be further subdivided. These special microwave quanta are very different from microwave particles in nature.

And the biggest technical difficulty is—”

Before Gu Qing finished speaking, Zhou Xia said naturally: "The biggest technical difficulty is that the energy of the microwave quantum is extremely weak, and even the energy of a single microwave quantum is only one ten-thousandth of the energy of a photon.

Therefore, this kind of microwave quantum must be captured by a special superconducting receiver close to absolute zero, because even if it rises by 1 degree Celsius, the extremely small environmental noise will drown the microwave quantum.

Their theory is the same as ours. After all, this is a technology that has been discussed in the international academic frontiers these years. Both the United States and Britain want to do it, but they cannot complete the development of a normalized superconducting receiver.

Even if all the supercooling equipment in the world capable of creating this extremely cold environment could only be made by a few companies in the United States and Europe, we have developed better coolers long ago.

Two years ago, I heard that they built a cooler that can maintain the temperature at 0.01 degrees above absolute zero. Now it seems that this cooler gave them the conditions to continue their research.

But even with a cooler, they can't complete the follow-up development at this stage. After all, in nature, where is there such a cold and safe environment to keep the device superconducting?

There are also parts and equipment in an extreme cooling environment, how to connect and communicate with parts and equipment at room temperature? How are the signals translated? How does the system do it?

These are all questions!

Hey, these old boys are trying to scam me?

I said that just after returning from a break in the laboratory today, my grandson who just started college asked me this kind of question with last year's journal. "
