Vol 3 Chapter 2308: Distinctly different active defense systems

, the fastest update to the latest chapter of military technology!
While Wu Hao and the others were talking, the medium-sized intelligent unmanned assault vehicle was ready, 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 strong interest in their expressions: "This active defense system live ammunition interception test mainly demonstrates to everyone that the active defense system of our medium-sized intelligent unmanned combat vehicle is in Ability to respond to incoming threats.
This test is mainly divided into three parts. First of all, we will simulate the most common and most easily encountered RPG rocket attack on the battlefield, especially in urban street battles and many public security battles.
This is almost the longest weapon attack 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 more, followed by roadside bombs and landmines.
Therefore, in order to deal with the attack of RPG rockets, the rice army and other western armies have thought of many ways. Among them, the most common and well-known are the fence grilles 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 get stuck in the grille with denser gaps and cannot hit the body, so it cannot explode, and naturally cannot damage the vehicle.
Secondly, even if it explodes, these RPG rockets use the directional hollow charge used by the armor-piercing projectile. After the fuze hits the vehicle, the hollow tube in the bomb body is ignited, forming a powerful metal jet to penetrate armor.
But this kind of metal jet must closely fit the armor in order to exert its power. When it is detonated at a distance of tens of centimeters from the armor, the metal jet attacks the armored target again at a distance, and the power is too small. "
Speaking of this, Wu Hao paused for a moment, then changed his tone and continued: "Despite this kind of grille protection, there are many armored vehicles damaged by rockets on 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, and it is also a technology that all countries are eager to study.
At present, the active defense systems of various countries are mainly based on the principles of active defense systems on 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 blowing up and intercepting the incoming missiles and rockets.
I think 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 has one interception and destruction. If the interception fails, it can only be destroyed by incoming missiles and rockets.
At present, the active defense technologies unveiled by various countries are basically like this, and there is no innovation. This has also led to the fact that this technology has not been widely used. On the one hand, it is because the interception success rate of this technology is not so satisfactory, and it can only be better than nothing. In addition, the price is expensive. Let's not say anything else, just say that the four small shields (phased array radar) on the tank are very valuable.
Therefore, the current technology in this area is still in the exploratory stage of various countries and armies, and only a small number of troops are deployed. "
After speaking, Wu Hao glanced at the people who were listening carefully to his explanation, then smiled slightly, and then said loudly: "As for our active defense technology, it should be said that it is different from the active defense system mentioned above. Or two concepts, two completely different technologies.
First of all, the principle of our active defense system is very different from the active defense system that is currently researched and installed in various countries. Our active defense system does not use the method of damage and interception, but more like the rapid-fire gun on the ship, which uses the method of impact interception.
Although it may not have a high range of interception with close-to-explosive damage, it can achieve continuous interception, and the interception distance is relatively long, which can achieve mid-section interception.
That is to say, when missiles or rockets are flying, they are discovered and intercepted in real time. Improve interception accuracy by distance and time. Through continuous firing, the barrage is deployed in the air, so that the incoming target hits the barrage to achieve the goal of damage and interception. "
Hearing Wu Hao's words, Leader Meng said with a smile, "It's a bit like a Phalanx interception system."
"Yes, the principles are similar, but there are still big differences. First of all, our equipment is relatively small and can be installed on armored vehicles. Second, our active defense system is more intelligent, it does not require personnel to control, 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, so as to quickly detect and intercept, and buy time for the successful interception.
We know that the flight speed of missiles and rockets is very fast, so we must fight for every millisecond to react. "
Speaking of which~EbookFREE.me~ Wu Hao paused for a while and continued to speak with a smile: "Different from the phased array radar system used by other active defense systems, what we use is a thousand-channel lidar plus image recognition technology. , using high-power thousand-channel lidar and our intelligent image recognition system to build an environmental awareness area of ​​several hundred meters in the vicinity of 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 by the intelligent system, and important data information will be retained.
When the system detects that the flight trajectory of a flying target in the air is heading towards the armored vehicle, the active defense system will immediately lock the target for tracking, and then calculate the threat level. 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 for real-time calculation, we can accurately detect the flight trajectory of the incoming target, predict the flight trajectory in front of it, 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. "
