Chapter 301 Examination (Part 1)

"Then what else can we do?" Zhao Yanyan asked. Among the three, only Zhao Yanyan was the most suitable to be this curious questioner.

"The infrared system can be considered." Guo Tailai thought for a while and replied.

"Infrared?" Zhao Yanyan frowned: "Now snipers are lurking hundreds of meters or even more than one thousand or two kilometers away. The probability of infrared system detection is too low, right? And what a powerful infrared receiver ?”

"Not looking for someone directly." Guo Tailai shook his head and said, "Detect the muzzle flash and track the flying bullets to determine the position of the enemy sniper."

The principle is very simple, and you can understand it as soon as you say it. Even if you don't know the technology, you will know what's going on. All three of them nodded slightly.

"However, the requirements for equipment are relatively high." Guo Tailai continued: "It is necessary to have an excellent infrared camera and an excellent video signal processing chip. The hardware requirements are relatively high, and the research is relatively difficult. It may be a little more difficult to do it in China. .And this is the kind of late-after-event, which cannot be discovered in advance.”

"Then are there any less difficult ones?" Zhao Yanyan glanced at General Sun and Colonel Wang, and asked seriously.

As soon as this question came up, both General Sun and Team Leader Wang looked at Guo Tailai expectantly, expecting to say "yes" from him.

"Yes!" Guo Tailai really lived up to everyone's expectations and said the word that everyone was most looking forward to.

Zhao Yanyan also laughed, she knew that the fat man would never let her down.

"Detection through sound waves." Guo Tailai gave the answer without waiting for Zhao Yanyan to continue to ask: "It is realized by receiving and measuring the muzzle shock wave of the sniper rifle and the shock wave generated by the projectile flying. This is most effective for supersonic projectiles."

"Under normal circumstances, two kinds of shock waves are emitted when shooting light weapons, one is the shock wave produced by supersonic bullets, and the other is the muzzle shock wave produced by propelling gunpowder. In a short distance, the arrival directions of the two shock waves The position of the shooter can be accurately judged by time and time. If the distance is far away, the ballistic and shock wave parameters of the bullet need to be considered, and the type of bullet can also be judged by the pressure and cycle generated by the shock wave." Say what you know.

"How to judge the arrival direction and time of the shock wave?" Zhao Yanyan was very keen and asked the key point at once.

"Arrange a few microphones." Guo Tailai replied without hesitation: "A device that collects sound waves, and microphones are arranged in several directions around it. Specifically, how many microphones need to be arranged? The time difference to the sound wave is used to judge the distance and direction, the signal principle of GPS, the three-point positioning method or the multi-point positioning method, this should not be difficult, right?"

Colonel Wang and Zhao Yanyan were both pondering the feasibility of this technology. General Sun was close and didn't know much about the technology, but he also understood that it must be feasible for Colonel Wang and Zhao Yanyan to ponder.

Three-point positioning or multi-point positioning, the Beidou navigation system that is being developed in China, is directly ready-to-use. The slightly more complicated thing is to collect sound waves and filter clutter to improve accuracy.

"Well, if you want to do it comprehensively, you can collect the shooting sound wave parameters of various light weapons, and you can also determine what kind of weapon it is." Guo Tailai continued to add: "If it is bigger, it will be a vehicle-mounted or mobile platform-carrying type. If it can be made small, it can be worn by a single person. If it is too big, it can be fixed in the camp.”

These additions do not require too much technical foundation, and everyone can immediately understand whether it can be done, and nod frequently.

"Of course, this is also an afterthought type." Guo Tailai finally concluded: "But something is better than nothing. At least it is good to prevent the enemy snipers from firing a second shot."

General Sun nodded in agreement. Next to Team Leader Wang and Zhao Yanyan looked up and saw the excitement in each other's eyes.

These kinds of plans are all theoretically feasible, but there was no such cruel demand before, so few people in China considered it. In fact, in recent years, the research direction of domestic weapon systems has basically been catching up with the technology of developed countries. Foreign countries do not have this direction for the time being or secret research projects have not been made public, so domestic people do not know. It's not that there is no need, it's just that no one thought of it.

This time, if Zhao Xiangbei and Guo Tailai hadn't talked about sniper rifles, Chechen meat grinder Grozny, and peacekeeping troops, they probably wouldn't have heard the name of this anti-sniper detection system.

Fatty is indeed a senior military fan, he doesn't know what he is thinking about every day, and he can think so comprehensively about things that others have not thought of. A direction that no one has ever paid attention to, Guo Tailai was able to think of such an eye-opening active anti-sniper system from the principle of the cat's eye, and even gave two solutions to remedy the situation, all of which are theoretically feasible , but also a simple solution and a difficult solution.

Combining the three plans mentioned by the fat man, it is completely a systematic anti-sniper detection system from easy to difficult. There is basically no similar type of equipment at home and abroad. As long as the research continues in this direction, it may become another leading military equipment field in the world. The protection of peacekeepers, the increase of military strength, and the improvement of military technology are all of great significance.

What is even more speechless is that Guo Tailai is only a graduate of the Department of Precision Instruments, and he is still studying medicine by himself recently, which is completely out of line with these majors. What a pure layman can think of, these real soldiers and experts have never even thought about it. Facing the fat man, the three of them feel a little ashamed.

"At least the not-so-rigorous knowledge system and principles we have at present are feasible." Colonel Wang expressed his opinion to General Sun on the spot: "We will organize experts to conduct technical demonstrations when we go back, and strive to establish the project and produce products as soon as possible."

I dare not say whether the two systems of laser and infrared are feasible or not, but sonic detection is completely feasible. Colonel Wang is also a technical official. From the perspective of difficulty and feasibility of implementation, he can't find a reason not to pass it.

"Well, I have a small selfish intention." Guo Tailai saw that they were so vigorous and resolute, raised their hands decisively, and after attracting the attention of the three of them, he suggested in a low voice: "Can I let my alma mater join?"

Of course Zhao Yanyan has no objection, she is also from Shuimu University. General Sun and Colonel Wang exchanged glances and nodded.

"It is absolutely necessary to seek experts from Shuimu University for argumentation." Team leader Wang smiled and gave Guo Tailai an affirmative answer.
