The more Professor Zhou Xia thought about it, the more uncomfortable he became and his scalp became numb.
Gu Qing already had content related to Xuanwu projection in front of him.
What the old professor was talking about came from a new radar developed by a certain institute of Daxia Guodian Technology.
The radar works based on microwave quantum theory, and its use environment is also quite special. It must work at extremely cold temperatures. The performance and functionality of this radar match the harsh and special working environment.
It can detect objects up to 15 million kilometers away.
This extremely 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 radar can not only detect unknown asteroids, but also objects missed by other detection methods, such as spacecraft such as certain stealth satellites.
General radar relies on radio waves to work. It emits radio waves in the direction of the target through the antenna. After part of the radio waves are reflected back by the surface material of the target object, it is then received by the radar's receiving antenna. After system calculation, it can If the distance to the target is obtained and the emission and reflection frequencies are high enough, important parameters such as the direction, speed and even weight of the target object can be obtained.
It's just that this method of radar detection has very weak detection capabilities for distant targets due to the limitations of radio waves. Moreover, according to the radar detection distance formula that the maximum detection distance of the radar is proportional to the fourth root of the radar's maximum transmission power, When other conditions remain unchanged, if you want the detection range to be doubled, the radar's transmit power must be increased to 16 times, or if you want the detection range to be 10 times, the radar's transmit power must be increased to 16 times. The transmission power must be increased to 10,000 times its original value.
Xuanwu also thoughtfully posted an example here. The radar used by the United States for asteroid detection 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. external goals.
Now, a new radar developed by a certain institute of Daxia Guodian Technology can theoretically detect objects tens of millions of kilometers away.
This is almost similar to a certain radar under development of the Jiuzhou Science and Technology Aerospace Project.
After browsing through the information compiled by Xuanwu, Gu Qing sighed when he saw that the old professor still looked as depressed as a cucumber.
If I don't resolve this misunderstanding, will the professor be obsessed with it to death?
Zhou Xia looked at the contents of the report and felt that every word of these brilliant achievements was so dazzling that it made his heart tremble every time he read it.
"This is a report from last year. Although they only made a theoretical basis and did not produce specific objects, such parts require special equipment. How could they come up with the theory so quickly?
It's all my fault, I shouldn't have gone to that industry party, let alone drank, ugh.
what to do?
Should we let the company file a lawsuit with Charcot? This is simply, this is simply impossible!
I heard that the company is currently engaged in cross-border business with a group of British technology companies, 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 all obviously upright...but with this radar, I——"
"Yesterday you were still designing a new generation of parts. In order to upgrade the environmental restrictions to warmer parameters, you did nothing wrong. When you had the party, you also brought members of our security team with you, so you definitely did not leak it. confidential."
Gu Qing's gentle voice made Professor Zhou, who was immersed in self-blame and shame, pause.
"This is information from the Zhuhai Air Show six years ago. Daxia Electric Technology exhibited models of quantum radar and microwave photon radar. Although they are conceptual products with a science fiction color, according to subsequent interviews, Electronic Technology There is indeed relevant research in this area.”
After hearing this, Professor Zhou slowly raised his head.
He is an old expert in this field. How valuable are the two radars of Nature's Way?
.
Quantum radar is a cutting-edge radar that uses the principle of quantum entanglement. By measuring reflected photons, it can calculate the size, shape, directional speed and other physical properties of the target.
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 key performance such as target resolution, range, and response speed of the radar system.
Gu Qing saw that the old professor's eyes began to focus, and he continued: "The theoretical news about microwave quantum radar you see is only a new generation of technology based on this.
You are an old man engaged in research in this area. Of course you know that radio waves are also a kind of light, which can be divided into tiny particles that cannot be subdivided. These specially prepared microwave quanta are very different from the microwave particles in nature.
And the biggest technical difficulty is——"
Before Gu Qing finished speaking, Zhou Xia spoke naturally: "The biggest technical difficulty is that the energy of 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 quanta must be captured using a special superconducting receiver close to absolute zero, because even if it rises by 1 degree Celsius, the extremely small environmental noise will drown out the microwave quanta.
Their theory is the same as ours. After all, this is a technology that has been discussed at the international academic frontier for these years. The United States and Britain both want to do it, but they are unable to complete the development of normalized superconducting receivers.
Even though all the super cooling instruments in the world that could create such an extremely cold environment could only be manufactured by a few companies in the United States and Europe, we have already developed better coolers.
Two years ago, I heard that they built a cooler that could 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 the cooler, they are simply unable to complete subsequent development at this stage. After all, where in nature is there such a cold and safe environment to keep the device superconducting?
There are also parts and equipment in extreme cooling environments. How to connect and interoperate with parts and equipment at room temperature? How are signals translated? How does the system do it?
These are all questions!
Hey, these old boys want to defraud me?
I just came back from a break in the laboratory today, and my grandson who just entered college asked me this question with last year's journal. "
