Bright Sword Military System

Then Wang Xuexin found Su Liguo.

During this period of time, Su Liguo was very busy. He was not only responsible for the production, improvement and upgrade of radar, but also managed the production of radios and electronic tubes. In addition, he also had to follow Turing to learn the production of monocrystalline silicon. Now he is also involved in supplying monocrystalline silicon. Doping research and development work.

But Su Liguo enjoyed it, and he often sighed to others: "I used to do my own research behind closed doors, and only made some progress after several years of research. It's not an exaggeration to use the word 'closed doors' to describe it. Just like flying an airplane, there is a breakthrough in a few days, and a discovery in a few days... I have learned much more in the past few months than I have learned in the past few years!"

For a scholar, the greatest reward is to learn new knowledge and solve the confusion in his heart. Su Liguo is such a scholar.

Wang Xuexin found Su Liguo in Turing's laboratory. At that time, Su Liguo was tossing about inside with a mask on his body. Wang Xuexin waited outside for more than half an hour.

It is said that half an hour is not bad, but other times Su Liguo would go in for several hours, and he would not come out to take a breath until his body couldn't take it anymore.

"Head!" Su Liguo, who walked out of the laboratory with a tired face, took off his mask casually, and said apologetically, "I kept you waiting for a long time, and I can't let go of the work in hand..."

"Understood!" Wang Xuexin handed Su Liguo a cigarette, and said, "Mr. Su, although work is important, you should pay attention to your body, don't get tired!"

"Oh, it's okay!" Su Liguo replied indifferently: "The Red Army even climbed snow-capped mountains and crossed grasslands. What is my suffering?"

As he said that, Su Liguo lit a cigarette and took a few greedy puffs.

Then Su Liguo asked: "Leader, are you here to see the progress of doping? Actually, it has been realized, but we are looking for a more economical and effective way, after all, we need mass production!"

Wang Xuexin nodded.

Silicon chips are used in computers and put into the military, and indeed they cannot be limited to laboratory implementations.

Wang Xuexin is not in a hurry, because he knows that he will succeed in the end. If it doesn't work, he will use the knowledge of the system to unplug Turing another day...

Wang Xuexin said: "Mr. Su, it's not because of this that I'm here today. I have a new idea that I want to discuss with you and see if it works!"

"New idea?" Su Liguo, who had been slumped in a chair, suddenly regained his energy: "Is it about silicon chips?"

Wang Xuexin shook his head: "Let's put it this way, we have achieved positioning, right? And positioning is achieved through ranging. Sometimes I wonder, can we develop a range-measuring equipment for tanks!"

Su Liguo let out a "huh", he didn't expect this point at all, he didn't even understand why the tank had to measure the range.

"It's like this!" Wang Xuexin explained: "Tank gunners can only observe the target through the observation window or periscope. What they see is flat, and it is difficult to judge the distance of the target. However, firing shells requires knowing the distance of the target. This has always been the difficulty of tank gunners!"

Su Liguo understood the reason after a little thought, he nodded slightly and said, "That is to say, most of the tank gunners now fire by feeling?"

"Yes!" Wang Xuexin replied: "Or rely on the scale on the periscope to roughly estimate the distance of the target! If we can develop a range-measuring device that can accurately measure the distance, it will have a great advantage on the battlefield. Can hit fast and accurate!"

Su Liguo nodded to express his understanding.

It's not difficult.

If the gunner can read the distance directly from the device without spending time estimating, this will achieve "shooting fast".

The distance measured by the equipment must be more accurate than the estimated distance, and "accurate shooting" has been achieved.

After thinking for a while, Su Liguo asked: "Commander, what do you mean, we use a method similar to locating missiles to measure the distance to the target?"

"Almost!" Wang Xuexin nodded.

"But..." Su Liguo frowned: "The positioning of the missile depends on the pulse signal emitted from the missile. It is impossible for us to install a pulser on the enemy tank..."

Wang Xuexin asked: "Then, can we use radar to measure the distance? For example, when the radar wave hits the target, the receiver receives the reflected wave and calculates the distance from it?"

Su Liguo was silent for a while, then shook his head and said: "It can indeed be done, but one is that the radar is too big to be installed on the tank, and the other is that the radar needs a huge antenna to rotate on the top, so installing it on the tank will affect Its combat performance. More importantly, there may be many targets in ground combat. For example, several tanks with different distances are lined up in a pile. The radar reflection waves will detect multiple targets at the same time, so there will be multiple data... In the end We still don't know which data to use as the target distance!"

Wang Xuexin secretly praised Su Liguo. This Su Liguo is indeed an expert in electronics. He can accurately describe the disadvantages of radar with only his imagination... The electromagnetic waves emitted by radar are scattered, and there are errors. If a few enemy vehicles Tanks are likely to be indistinguishable in one piece.

But Wang Xuexin's final idea is of course not this.

He said: "If radar waves cannot be realized, can we find another method to calculate the distance by receiving and reflecting the same method?"

Su Liguo thought for a while, then shook his head and said, "Head, there probably isn't such a thing now, if there is, other countries would have used it long ago!"

Then Su Liguo added: "However, if we want to achieve accurate range measurement of the target, it must be different from the scattered electromagnetic waves of the radar. It should be concentrated!"

Wang Xuexin let out a "hmm", and these words were getting closer to what he wanted.

Because only concentrated things can accurately select one of a group of targets and measure the distance, otherwise several data will be obtained.

Wang Xuexin said: "Old Su, if electromagnetic waves are not good, is it feasible to use light?"

"Light?" Su Liguo was taken aback: "You mean laser light?"

Then Su Liguo laughed: "Leader, your idea is very correct, and it has been proved to be feasible in theory, but no one has realized it yet!"

Wang Xuexin thought that Su Liguo really knew a lot.

The laser was realized in 1960, and the laser rangefinder was invented in the same year.

It was first proposed by Einstein, and after decades of demonstrations, it has remained in theory until 1960, when a scientist named Meimanli in Eagle Sauce discovered laser light by stimulating rubies with high-intensity flashlights...

Now that Wang Xuexin is here, is it Mei Manli's turn to invent?
Is this invention good for us?
