While Wu Hao and the others were talking, the 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.

As for Wu Hao, he introduced with a smile to the people who showed great interest in their expressions: "This live-fire interception test of the active defense system is mainly to demonstrate to everyone that the active defense system of our medium-sized intelligent unmanned combat vehicle can The ability to cope with incoming threats.

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

This is almost the longest weapon attack encountered on the battlefield, because it is cheap enough, simple enough, and violent enough, so it basically appears active on every battlefield.

Even the Mi Army has relevant statistics. Among the many attacks they encountered, the number of RPG rocket attacks was the most, followed by roadside bombs and landmines.

Therefore, in order to deal with the attack of RPG rockets, the Mi Army and other Western troops have thought of many ways, the most common and well-known of which is the fence grille welded and installed on the periphery of many armored vehicles and tanks. This grille will effectively defend against rocket attacks.

The principle is that the rocket will be stuck in the grille with dense gaps and cannot hit the car body, so there is no way to explode, and naturally it cannot hurt the vehicle.

Secondly, even if it explodes, these RPG rockets use the directional hollow charge used in armor-piercing projectiles. After the fuze hits the vehicle, it ignites the hollow charge tube in the projectile body, forming a powerful metal jet to penetrate armor.

But this kind of metal jet must be closely attached to the armor in order to exert its power. After detonating tens of centimeters away from the armor, the metal jet will attack the armor target again after a certain distance, and its power will be much smaller. "

Speaking of this, Wu Hao paused for a moment, then changed his tone and continued: "Despite the protection of this grille, armored vehicles damaged by rockets abound on all major battlefields.

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

At present, the active defense systems of various countries are mainly based on the principles of active defense systems on the new tanks equipped by the Goose Army. Simply put, they use phased array radar to scan the surrounding environment of armored vehicles in real time. Or after the rocket, the interceptor on the armored vehicle will launch an interceptor according to the angle. This interceptor bomb will explode near the incoming missiles and rockets, thereby destroying and intercepting the 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 only intercepts and destroys it once. If the interception fails, it can only be hit and destroyed by incoming missiles and rockets.

At present, basically the active defense technologies unveiled by various countries are basically like this, without any innovation. This has also led to the delay in the large-scale application of this technology. On the one hand, it is because the interception success rate of this technology is not so satisfactory, it can only be better than nothing. The other is that the price is expensive. Let alone other things, just say that the four small shields (phased array radar) on the tank are very valuable.

So at present, regarding the technology in this area, all countries and armies are still in the groping stage, and only a small number of troops are deployed. "

As he spoke, Wu Hao glanced at the people who were listening carefully to his explanation, then smiled slightly, and then raised his voice and said: "And our active defense technology should be said to be different from the active defense system mentioned above. In other words, there are two concepts, two completely different technologies.

First of all, the principle of our active defense system is very different from the active defense systems currently researched and installed in various countries. Our active defense system does not use the method of damage interception, but is more like a rapid-fire gun on a ship, which uses the method of impact interception.

Although the range of interception may not be as high as that of close bomb damage, it can achieve continuous interception, and the interception distance is relatively long, which can achieve mid-range interception.

In other words, during the flight stage of missiles or rockets, they are discovered and then intercepted in real time. Improve interception accuracy with distance and time. The barrage is deployed in the air by continuous firing, so that the incoming target hits the barrage to achieve the target of damage and interception. "

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

"Yes, the principle is somewhat similar, but there is still a big difference. First of all, our equipment is relatively small and can be installed on armored vehicles. Second, our active defense system is more intelligent, and it does not require personnel to control it. We can discover the target by ourselves, and attack and intercept the incoming target. In this way, we have a faster reaction speed than humans~lightnovelpub.net~ so that we can quickly discover and intercept quickly, and buy time for successful interception.

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

Speaking of this, Wu Hao paused for a moment and continued with a smile: "Different from the phased array radar system used by other active defense systems, what we use is a thousand-channel laser radar plus image recognition technology, using high-power thousand-channel Lidar and our intelligent image recognition system to build an environment awareness area with a radius of hundreds of meters near the armored vehicle.

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

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

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