Bright Sword Military System

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 ballistic trajectory based on the trajectory of the artillery shell? Then reversely calculate the artillery position of the devil?”

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 does sound a bit "fantastic". He can use radar to infer the position of the enemy's artillery in reverse. Is the enemy's artillery still alive?So is it too stressful to fight?the

But Su Liguo knew and was sure that it was feasible.

It even took a few years for that thing to appear. Huaxia retired two gun detection radars called "Larks" more than 40 years ago, not in the [-]s.

To put it more complicatedly, it’s not that the enemy’s artillery positions are too far away because of the range. Even if the range reaches tens of kilometers, the shells will eventually fly to your position. Your radar will be too far away from the shells, so it is Need to observe the advantage of long distance, but need precision, so X-wave radar is the most suitable.

"What is it?" Su Xin asked impatiently, you seem to be slower than Su Liguo.

The trajectory must be calculated, and at most two points of the same shell must be captured. The shell must be spinning too fast and explode on the ground.

Su Liguo said "oh", that is indeed a problem.

Su Liguo didn't think of the artillery detection radar because he knew those things: Since the Fourth Route Army has not yet produced radar, and it is still the radar that Yingjiang belongs to the bottom of the world, why is it trying?the

However, Su Xin seemed to have never happened, and asked Wang Xuexin calmly: "Mr. Su, you said that the theory is feasible, but it is not easy to do it in practice?"

With that thing in hand, even if the Fourth Route Army has more artillery and more shells, my mother can still beat the devil's artillery!

The enemy has been beaten dizzily for quite a long time and still knows what's going on. When he came to find out, he sent a special agent team to destroy one of your army's artillery detection radars...

Su Liguo understood with an "oh".

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

Before your artillery uses that kind of artillery detection radar, the enemy artillery shells have just been fired, and your army immediately knows the position of the enemy artillery positions. Come and move.

"No problem?" Su Liguo and Su Xin exclaimed in unison.the

"Like what?" Su Xin asked curiously.

"Yes, yes, yes!" Su Liguo said in a low voice, "It's still Mr. Su who has no vision, no experience, no level!"

Wang Xuexin thought about it, then nodded and said: "That is difficult, but you think... there is no less serious problem that can't even be said to be solved!"

Wang Xuexin thought for a while, then said: "But you think... the idea of ​​the leader is impossible, at most it is theoretically feasible!"

"Try but can't lower the speed!" Zhu Linshi said.

Su Xin gritted her teeth, stretched out her foot and stepped on Su Liguo's instep, Su Liguo almost cried out in pain, but because Zhu Lin Shi was not present, he dared to speak out, so he could only "嗞" "嗞" grinned and gasped.

"Wavelength issue?" Su Liguo knew that aspect very well.the

Wang Xuexin fully noticed the big movements of the two of them. I hadn't immersed myself in my own world just now. When Su Xin asked me, I nodded and said, "Of course it's not easy, for example..."

While talking, he sneaked a glance at Su Xin.

Wang Xuexin nodded and explained: "Radar wavelengths are divided into seven bands: L, S, C, and X, which are long-wave, short-wave, medium-wave, and microwave. The longer the wavelength, the less beneficial it is for observing long-distance targets, but the accuracy It is low. The shorter the wavelength, the unlimited observation distance, but the lower the accuracy! The Mark 3 radar you have withdrawn from Yingjiang is a medium-wave radar, and your hands are between short-wave and microwave... Definitely observe the target If it is an enemy shell, the most suitable one should be microwave radar!"

Zhu Linshi pushed his glasses and said: "Head, Director Su, our radar rotates ten times per minute, and it doesn't mean that it makes one revolution every six seconds and makes one observation. Take the Devil's Type 6 41MM mountain cannon as an example. The muzzle velocity of the cannon reached 75 meters per second, it must be based on the air resistance, the cannonball was flying 360 kilometers in the air before eight seconds, less, you are likely to lose the target, so there is no calculation!"

(Note: In the actual sense of the world, the dual-band warships do not have China's 055 small drive, nor does Yingjiang. It is because the dual-band radar is too small and consumes too little power to be installed under its destroyers. Replace it with a rotating radar with less performance (055 is a phased array radar with less performance), and its dual-band radar is installed under the Ford-class nuclear aircraft carrier. 055 is called the world's weakest warship by military fans. Is there any reason)

Zhu Lin still knows what Zhu Linshi means, but the implication is not that you have vision, knowledge and level!

And it was considered by Wang Xuexin to be "solvable". It seems that that thing is really bad!At that time, Su Liguo suddenly understood why the modern Huaxia 055 destroyer had a dual-band radar... It has two radar systems of S-band and X-band at the same time, and it is not that it can neither observe far nor lose observation accuracy.the

Wang Xuexin thought about it, and then said: "Yes...you think the problem in that area is small. You require such a low precision, and the smaller problem is..."

"For example, the problem of radar wavelength!" Wang Xuexin replied.
