Chapter 686;
Wen Guozhong left regardless of his daughter's anger, but said to Jiang Xinwei: "Boy, my daughter is the best woman in the world, and I will leave it to you." You say, how do you crack the stealth technology?"
Jiang Xinwei hurriedly broke free of his hands and said, "I just have some experience and ideas. Can you sit down and listen to me?"
Wen Guozhong said yes again and again, and his body reluctantly retreated, and as soon as his ass sat down, he couldn't wait to urge in his mouth: "Boy, if you have a fart, let it go, why haven't you spoken for a long time?"
Jiang Xinwei said: "The so-called stealth technology is actually to avoid radar detection to a certain extent. The first method is to lay a layer of coating on the surface of a stealth aircraft or stealth missile that can absorb radar waves, and absorb the electromagnetic waves that irradiate the body, so that the radar will naturally not be able to detect it. The second method is to change the shape of the aircraft or missile, changing the shape of their radar reflective surface as much as possible, so that the irradiated electromagnetic waves are not reflected back, but reflected in other directions. The radar cannot receive the electromagnetic waves emitted by itself, so it will naturally not be able to detect the target. ”
Wen Guozhong said: "I understand this principle, you can talk about the solution." ”
Jiang Xinxu said: "For the second method, I can't solve it. However, the stealth effect obtained by the second method is actually limited, although the aircraft and missiles can be designed for stealth, but no matter how it is designed, it is impossible to do it completely not reflect back the electromagnetic waves, at most it is reduced by half, reduced by two-thirds, after all, whether it is an aircraft or a missile, it must be loaded with things, and it must have a certain volume. Besides, the direction in which the radar irradiates the aircraft and missiles is not fixed, and there may be radars around the aircraft or missiles, so it is impossible to consider such a comprehensive ...... no matter how it is designed."
Wen Guozhong hurriedly said: "Then you say the first method, the first method of how you can crack the stealth technology." ”
Jiang Xinwei said: "I am engaged in telecommunications, and I am studying the field of telecommunications, so I naturally consider problems from the perspective of telecommunications technology. Isn't the coating they put on to absorb electromagnetic waves? I can't let them absorb it, right?"
Wen Guozhong was dumbfounded, and asked incoherently: "Why do you make them unable to absorb electromagnetic waves? Do you have a way to make them fail? Impossible, the coating is on the plane, how do you make it fail? Oh, are you going to give the stealth plane a lot of electromagnetic waves, so much that they can't absorb them all, just kill it?"
His eyes lit up, but then he shook his head and said: "Impossible! Impossible! We don't know where the plane is, and how can we send enough electromagnetic waves to it so that they can't eat it? If we release a large amount of electromagnetic waves in all directions and all over the sky, how can we have such a high-power radar? What kind of powerful power is needed, and what kind of powerful logistical support is needed? No, no, you can't do this method. ”
Jiang Xinwei said: "You are right, the way I want to do it is to hold it to death so that it can't absorb it." However, my solution is not to increase the power of electromagnetic waves, let alone to send electromagnetic waves into the sky. ”
Wen Guozhong hurriedly asked, "What is your solution?"
Jiang Xinwei said with a smile: "My method is to emit electromagnetic waves of various frequencies and frequency bands to exceed the frequency bands it absorbs. As far as I know, the so-called stealth coatings can only absorb the electromagnetic wave frequency band emitted by common radars, as long as it is not the electromagnetic wave of this frequency band, these coatings cannot absorb it. ”
Wen Guozhong asked in disbelief: "Really? Do they really only absorb electromagnetic waves in a certain spectrum?"
Jiang Xinwei nodded and said: "Electromagnetic waves can be divided into many kinds according to wavelength, there are meter waves, centimeter waves, millimeter waves, and even micron waves. ”
Wen Guozhong sighed and said: "Then we have to change the transmitting and receiving unit of the radar, the current radar spectrum is the frequency that has been selected after decades of optimization, if we switch to other spectrum, change to other frequency bands, this is not a small workload." ”
Jiang Xinxu said: "Of course it is not small, the meter-wave radar or something, the volume is much larger than the current radar, the cost is much higher, and the role is also single, if it is not for the purpose of cracking the stealth, who would want to do it? Isn't it because the United States has taken advantage of this feature to develop the stealth coating? And I believe that they will develop more and more extensive coatings that are more and more suitable for more frequency bands." ”
Speaking of this, he confidently said: "Of course, we can also develop more and more radars of various wavelengths and frequency bands." As the saying goes, if you are one foot tall, you will see who has the last laugh. ”
Wen Guozhong gave a thumbs up and said, "Yes, what I appreciate most is that you don't admit defeat!"
Jiang Xinwei smiled and said, "General Wen, what you say is a bit insincere, right? I think what you appreciate most is that I am stupid, that is, I pay you for no reason." ”
Wen Guozhong laughed out loud and said, "Haha, you can't say that, you are generous." Besides, this money is for the state, and I personally can't get a penny. Also, don't think that you have suffered a lot of losses, don't you have to dig up national experts every time? I don't think you will be generous enough to contribute money to us this time, right?"
Jiang Xinxu replied: "There is no way. We are a private enterprise, and we are engaged in telecommunications products, so where can we have the ability to develop military products and equipment? If we do not ask for people from you, how can we proceed and fulfill your tasks? …… As for this time, I'm going to have 10 experts in sensors and 10 experts in wireless communications. When they are in place, we will start working on them. ”
Wen Guozhong's eyes widened, and he said angrily: "Boy, how can you ask for such a sky-high price? Twenty experts, why don't you grab them? And we just need radar, why do you want experts in these fields?"
Jiang Xinxu said: "The frequency band of the radar must be constantly changing, and the corresponding radar transmitting unit and receiving unit are not sensors?
Wen Guozhong said depressedly: "What about wireless communication experts?"
Jiang Xinwei said: "It's very simple, the electromagnetic wave emitted by the radar itself is a kind of wireless signal, but it does not carry information, and once the radar captures the target, should it be transmitted to the superior? Moreover, for the capture of stealth planes and missiles, it is not as simple as detecting old planes in the past, and it is necessary to detect from different positions and different directions at the same time, looking for different directions on the reflective surface. To put it bluntly, several radars must detect at the same time, and information must be shared between several radars to ensure that nothing goes wrong. You say, do I want a wireless communications expert?"
His words are high-sounding, how can it sound like this, but what about the reality?
