He knows the technical principle, and now, if it is said that it is necessary to launch a powerful laser beam in the past, so as to kill the enemy's equipment, this is a way, a relatively simple way, just like the Soviets engaged in a ballistic missile defense system, because it cannot be guided to the level of precise collision, so simply come to a nuclear warhead, relying on the expansion of the killing radius of the warhead to destroy the enemy's ballistic missile, this way is more crude, primitive, direct, but it requires a lot of energy.

Now, instead of directly using a powerful laser beam to hard-kill the enemy's sighting system or even eyes, it is necessary to interfere with and suppress the opponent's laser rangefinder, so it must have more advanced performance.

What does it entail?

First of all, it needs to be encoded and decoded, and it needs to completely simulate the other party's laser beam.

The principle of laser ranging is as simple as radar, the past is a pulsed laser beam, for example, an interval of 1 millisecond, a pulse is emitted, and then, if it encounters a target, it is reflected back, which must be within a millisecond, before the second pulse does not go out, the first pulse is reflected back, so as not to cause errors, otherwise, the second pulse passes, the first pulse is reflected back, then, the reflection back, is it the first pulse, or the second?

No one knows, can't tell, so there's no way to measure the distance.

This suppression system of the own side is to artificially transmit more pulses between the two pulses of the other party, so that the other party can receive them, so as to lose the ability to judge and find the real pulse signal, then, in this way, it means that the pulse signal of the other side must be the same as the pulse signal of the other party, and this system of the other side will distinguish the pulse signal of the other party and simulate the pulse signal of the other party.

In this way, the power required is greatly reduced, but the complexity of the technology is greatly increased.

Or to use radar as an example, the MiG-25's radar power is so strong that some media misrepresent that it can burn a rabbit or something, so, is its radar powerful? Of course not, this kind of radar has super power, but it does not have a large enough processing power, the range is limited, the resolution is very poor, and in the end it can only guide a medium-range missile with a range of tens of kilometers.

The Tomcat fighter's radar does not have such powerful power, but it has a high enough processing power, so it can irradiate hundreds of kilometers at most, and the target can be clearly distinguished, and the latter's technical degree is far beyond the former.

After sensing the laser beam fired by the other party, then distinguishing, then simulating, and launching back, these must be completed in a short period of time, and the other party cannot be allowed to complete the work of ranging, so the difficulty and complexity of such a system are far more than the hard killing of a simple laser beam.

"In other words, this system can recognize the encoded information of laser pulses, and it also has the ability to distinguish friend and foe on the battlefield?" The thirty-something Navy officer continued to ask.

"Yes." Wang Xiaoyu said: "Based on this system, we are currently developing a battlefield identification system for friend or foe, as well as an exercise system for battlefield simulated confrontation training. The research and development of related systems has entered the final stage, and the first generation of products will soon be available. ”

On the battlefield, the identification of friend or foe is the most important!

In the war in the oil area, the Sam-6 missile once showed great might, but at the same time, because of the lack of the ability to distinguish between friend and foe, so they used a simple method to divide the defense area, as long as they flew over me, those who came did not refuse, and completely shot down, so although they shot down a lot of Israeli fighters, but the probability of their own fighters being hit by mistake is also a lot, in a complex air battle, who cares about the limitation of the air defense area!

On fighter planes, there are friend or foe identifiers that can be installed, but on land, it will be difficult.

In a battle, if the exchange of fire has just begun, the big guy rushes up and beats him hard, of course, he can distinguish between the enemy and the enemy, as long as he fires at the opposite side, but what about when he rushes in?

Rushing to a close place, or even staggering between friend and foe, how to identify friend and foe at this time? Especially the most ruthless one, you may rush past the enemy's tank formation, and then turn around from behind, and what if your side sees the direction of the opponent's advance and misjudges it as an enemy army?

In the past, World War II relied on visual vision, and various tanks could be recognized at a glance by the eyes of tankers, but now, with the increase in the distance of firefights, it is likely that there is no opportunity to observe them visually.

Now, there is a way to use this laser suppression system, which can recognize the information of the opponent's laser rangefinder, and can determine friend or foe based on this information.

At the same time, on the training ground, it will also be of great use!

In the past, the training and exercises were all one-sided, and the Red Army roared past and fired at one target after another, and those targets could not be manned, otherwise they would be injured by mistake, so this kind of exercise was never real.

Can it be like a real war, where the enemy and the enemy are mixed and mixed, and then, you aim at me, I aim at you, and whoever strikes first loses?

How do you determine this?

Is it me that you aim at first, or do I aim at you first? Who knows if you don't fire?

At this time, it is difficult to say.

Now, Wang Xiaoyu has provided a solution, a battlefield laser countermeasure system. This system is simply a must-have for exercises tailored to the military. If you have watched "Soldier Assault", there is the kind of system that simulates the effect of live ammunition and does not hurt people, and there is a system that automatically determines that it smokes after being hit, in fact, it is this kind of battlefield laser countermeasure system.

In fact, this system was invented very early, as early as the 60s, France and Germany developed similar things, but, after all, the electronic equipment at that time had limited performance and could not really meet the needs of actual combat, and the system that really realized the judgment induction after shooting and being hit was developed and put into use by the Americans in the 80s.

After years of research and development, they finally developed a breakthrough multifunctional integrated laser engagement training simulation system for infantry and armored vehicles (MILES), which was first equipped at the Fort Irwin military base at the U.S. National Training Center in 1982.

The technological gap between the big countries in the East is very large, in the past, I could only look at the advanced and modern people drooling, but now, I finally have the ability to research and develop.
