Chapter 1314 Gun Reconnaissance Radar
Speaking of this, Wang Xuexin stopped playing charades with Su Liguo, and he directly expressed his thoughts: "Old Su, I have an idea, if we can use radar to detect the shells fired by the enemy's artillery, that is Isn’t it possible to calculate the trajectory of the artillery shell based on its trajectory? And then reversely calculate the artillery positions of the devils?”

As soon as these words came out, Su Liguo was stunned. Su Xin also looked at Wang Xuexin with incredible eyes while listening to him.

After a while, Su Xin asked in doubt: "Student Wang, you don't want to use this method to gain an advantage in artillery, do you?"

"Isn't it?" Wang Xuexin replied: "If this calculation can be done in this way, then we don't need any artillery observers to do the calculations. We can directly use the radar to calculate the artillery positions of the devils, so we can hit one accurately! So what if we don't have enough shells or enough artillery? Isn't the devil's artillery only to be beaten?"

Su Liguo and Su Xin couldn't help but look at each other. They both have research on radar, especially Su Liguo, who likes to tinker with radios, sound waves and the like all day long, but he didn't expect radar to be able to so use.

"Xiao Wang!" Su Xin couldn't help but said, "Aren't you a little whimsical, how can it be so easy!"

Wang Xuexin just smiled and didn't speak.

He can actually understand Su Xin. It sounds a bit "fantastic". He can use the radar to infer the position of the enemy's artillery in reverse. Is the enemy's artillery still alive?Is it too easy to fight like this?
But Wang Xuexin knew and was sure it was feasible.

It didn't even take a few years for this thing to appear. Huaxia imported two gun detection radars called "Larks" more than forty years later, that is, in the 90s.

After our artillery used this kind of artillery detection radar, the enemy artillery shells had just been fired, and our army immediately knew the position of the enemy artillery positions, and then the artillery shells immediately passed by in pieces, and the enemy artillery had no time to move.

The enemy was beaten so dizzy for quite a long time that he didn't know what was going on. Later, when he found out, he sent a special agent team to destroy one of the artillery detection radars of our army...

It was because Wang Xuexin knew these things that he thought about whether he could develop artillery detection radar: Since the Eighth Route Army has been able to produce radar, and Yingjiang belongs to the top radar in the world, why not try it?

If this thing comes out, even if the Eighth Route Army has less artillery and fewer shells, the **** can still beat the devil's artillery!

Su Liguo thought for a while, and then said: "But I think...the idea of ​​the leader is possible, at least theoretically feasible!"

"Yes, yes, yes!" Wang Xuexin said happily: "It's still Mr. Su who has vision, knowledge and level!"

While talking, he sneaked a glance at Su Xin.

Su Xin still doesn't know what Wang Xuexin means. The implication is that she has no vision, no experience, no level!
Su Xin gritted her teeth, stretched out her foot calmly and stomped hard on Wang Xuexin's instep, Wang Xuexin almost cried out in pain, but because of the presence of Su Liguo, he could only grin and twitch Cool.

However, Su Xin seemed like nothing had happened, and asked Su Liguo calmly: "Mr. Su, you say this theory is feasible, but it is difficult to implement it in practice?"

Su Liguo didn't notice the small movements of the two of them at all. He was already immersed in his own world just now. When asked by Su Xin, he nodded and said, "Of course there are difficulties, such as..."

"Like what?" Su Xin asked curiously.

"For example, the problem of radar wavelength!" Su Liguo replied.

"Wavelength problem?" Wang Xuexin didn't know much about this aspect.

Su Liguo nodded and explained: "Radar wavelengths are divided into four bands: L, S, C, and X, which are long-wave, short-wave, medium-wave, and microwave. The longer the wavelength, the better it is for observing long-distance targets, but the accuracy is not good. High. The shorter the wavelength, the limited the observation distance, but the higher the accuracy! The Mark 3 radar we imported from Yingjiang is a medium-wave radar, that is, between short-wave and microwave... If the observation target is an enemy shell, The most suitable one should be microwave radar!"

Wang Xuexin understood with an "oh".

To put it simply, the enemy's artillery positions will not be too far because of the range. Even if the range reaches tens of kilometers, the artillery shells will eventually fly to our positions. Our radar will not be too far from the artillery shells, so there is no need The observation distance is an advantage, but precision is required, so X-wave radar is the most suitable.

At this time, Wang Xuexin suddenly understood why the modern Huaxia 055 destroyer has a dual-band radar... It has two sets of S-band and X-band radar systems at the same time, that is, it can observe far and accurately.

The so-called dual-band radar of the Guizi Qiuyue class is C-band and X-band. The reason why it is called tasteless is because the two bands are too close. Although the observation distance of the C-band is farther, it is not far away.

(Note: The actual dual-band warships in the world are only Huaxia’s 055 large drive, and Yingjiang also has them, but because the dual-band radar is too large and consumes too much power, it cannot be installed on its destroyers, so it can only be used with poor performance. It is replaced by more rotating radars (055 is a phased array radar with much stronger performance), and its dual-band radar is installed on the Ford-class nuclear aircraft carrier. It is not without reason that 055 is called the world's strongest warship by military fans)

Su Liguo thought for a while, and then said: "However... I don't think this is a big problem. We don't require such high precision. The bigger problem is..."

"What is it?" Su Xin asked impatiently, she seemed more anxious than Wang Xuexin.

Su Liguo pushed his glasses and said, "Head of the regiment and director of the factory, our radar makes ten revolutions per minute, that is, one revolution per 6 seconds for one observation. Let me take the Devil's Type 41 75MM mountain cannon as an example. This cannon The muzzle velocity reached 360 meters per second, if the air resistance is not taken into account, after six seconds the shell would have been flying more than 2 kilometers in the air, and we would probably lose the target, so there is no way to calculate it!"

Wang Xuexin said "oh", this is indeed a problem.

If you want to calculate the trajectory, you must capture at least two points of the same shell. If the speed is too slow, the shells will explode on the ground, and you still need to detect farts.

"Try if you can increase the speed!" Wang Xuexin said.

Su Liguo thought for a while, then nodded and said: "This is not difficult, but I think... there are more serious problems that can even be said to be unsolvable!"

"Is there a problem?" Wang Xuexin and Su Xin exclaimed in unison.

Moreover, it was considered "unsolvable" by Su Liguo. It seems that this thing is really difficult to fix!
