Military Technology

While Wu Hao and the others were talking, this medium-sized intelligent unmanned assault vehicle had been prepared, and the most anticipated live-fire demonstration of the active defense system was finally about to begin.

Wu Hao, as for Wu Hao, smiled and introduced to everyone who showed great interest: "This live-fire interception test of the active defense system is mainly to demonstrate to everyone the active defense system of our medium-sized intelligent unmanned combat vehicle. The ability to respond when encountering incoming threats.

This test is mainly divided into three parts. First, we will simulate the RPG rocket attack that is most common and most likely to be encountered on the battlefield, especially urban street fighting and many security battles.

This is almost the longest weapon attack you will encounter on the battlefield. Because it is cheap enough, simple enough, and violent enough, it is basically active on every battlefield.

The US military even has relevant statistics. Among the many attacks they encountered, the number of RPG rocket attacks was the largest, followed by roadside bombs and landmines.

Therefore, in order to deal with RPG rocket attacks, the American army and other Western armies have thought of many ways. The most common and well-known one is the fence grille welded and installed on the periphery of many armored vehicles and tanks. This kind of grille will effectively protect against rocket attacks.

The principle is that the rocket will get stuck in the grille with dense gaps and cannot hit the car body, so it cannot explode and naturally cannot damage the vehicle.

Secondly, even if they explode, these RPG rockets use the directional hollow charge used in armor-piercing projectiles. After the fuze hits the impact vehicle, it ignites the hollow charge tube in the missile, forming a powerful metal jet that penetrates Armor.

But this kind of metal jet must fit tightly into the armor in order to exert its power. When detonated tens of centimeters away from the armor, the metal jet attacks the armored target again at a distance, and the power is much smaller. "

At this point, Wu Hao paused for a moment, then changed his tone and continued: "Despite this grille protection, armored vehicles damaged by rockets are everywhere on various battlefields.

Therefore, a better defense technology must be developed, so military technical experts from various countries have thought of many ways. Among them, the active defense system is the most promising, and it is also a technology that all countries are vying to study.

The current active defense systems in various countries are mainly based on the principles of active defense systems on new tanks equipped by the Go Army. Simply put, they use phased array radar to scan the surrounding environment of armored vehicles in real time. When incoming missiles are detected, Or after a rocket launch, the interceptor device on the armored vehicle will launch an interceptor missile according to the angle. This interceptor will explode near incoming missiles and rockets, thereby destroying and intercepting incoming missiles and rockets.

This kind of active defense technology is much stronger than passive defense armor, but it also has a problem, that is, it uses terminal interception, that is to say, it can only be destroyed once. If the interception fails, it will only be hit and destroyed by incoming missiles and rockets.

At present, the active defense technologies unveiled by various countries are basically the same, without any innovation. This has also led to the fact that this technology has not been widely used. On the one hand, this is because the interception success rate of this technology is not so satisfactory, it can only be better than nothing. The other thing is that it's expensive. Let's not talk about anything else. The four small shields (phased array radar) on the tank are worth a lot of money.

Therefore, currently, the militaries of various countries are still in the exploratory stage regarding this technology, and only a small number of troops have been commissioned. "

As he spoke, Wu Hao glanced at the people who were listening to his explanation attentively, then smiled slightly, and then spoke loudly: "As for our active defense technology, it should be said that it is two different things from the active defense system mentioned earlier. In other words, they are two concepts, two completely different technologies.

First of all, the principle of our active defense system is very different from the active defense system currently being researched and installed by various countries. Our active defense system does not use a damage and interception method, but is more like a rapid-fire cannon on a ship, using a collision and interception method.

Although it may not have as high a range as close-in damage and interception, it can achieve continuous interception, and the interception distance is relatively long, and it can achieve mid-course interception.

In other words, the missiles or rockets are discovered during their flight stage and then intercepted in real time. Use distance and time to improve interception accuracy. By continuously firing, a barrage is laid in the air, allowing the incoming target to hit the barrage to achieve the goal of damaging and intercepting it. "

Hearing Wu Hao's words, Leader Meng smiled and said: "This is a bit like the Phalanx interception system."

"Yes, the principles are somewhat similar, but there are still big differences. First of all, our equipment is relatively small and can be installed on armored vehicles. Secondly, our active defense system is more intelligent and does not require human control. We can discover the target by ourselves, attack and intercept the incoming target. In this way, we have a faster reaction speed than humans, so we can quickly discover and intercept the target quickly, buying time for successful interception.

We know that both missiles and rockets fly very fast, so we must gain every millisecond to react. "

Speaking of this, Wu Hao paused and continued with a smile: "Different from the phased array radar system used by other active defense systems, what we use is 1000-channel laser radar plus image recognition technology, using high-power 1000-channel laser radar LiDAR and our intelligent image recognition system create an environment awareness area of ​​several hundred meters around the armored vehicle.

All targets in this area will be detected and captured by our system, and useless and secondary information will be filtered out through the intelligent system, while important data will be retained.

When this system detects that the trajectory of a flying target in the air is heading towards an armored vehicle, the active defense system will immediately lock on the target for tracking, and then calculate the threat level. When it is confirmed that the target poses a serious threat to its own safety, the active defense system will The defense system will remotely control the machine gun of the turret or the weapon station above to intercept incoming targets.

Because there is a powerful intelligent system performing real-time calculations, we can accurately detect the flight trajectory of the incoming target, predict its forward flight trajectory, and then implement early attack and interception. In this way, we can use this system The interception success rate against incoming targets has been raised to a new level. "
