Of course, this is just about the technical problems of flying drones at high speeds and crossing obstacles.
For this drone to be able to quickly find targets and identify targets for attack, this is also a technical problem that they urgently need to solve.
If you want to solve this problem, you must first figure out what targets their 'Battlefield Cleaner' high-speed small attack drone swarm strike system is used to target.
First of all, the most important target is definitely those enemy soldiers in a non-enclosed environment. This is the main target of this strike weapon.
Secondly, there are some ammunition piles, mortar positions, or some important enemy military nodes.
In addition, in Wu Hao's design, this attack drone will also have a certain attack effect on some light vehicles. Of course, a single drone has a limited amount of explosives.
But if the drone's explosive charge is specially designed so that it can explode in a forward direction. Multiple drones form an attack team and continuously attack a point on the target in a short period of time. The high-pressure metal jet generated by the directional blasting will also cause a breakdown effect on the thin body of the vehicle.
This principle is a bit like some tandem-charge armor-piercing projectiles or tandem-charge earth-penetrating projectiles. When facing ultra-high-strength armor or ultra-thick concrete bunkers, armor-piercing bombs and ground-penetrating bombs use the relaxation and progression of this continuous blasting until they penetrate the protective armor and reach the target.
If the task of detection, discovery and identification is left to people, there will definitely be no problem. Even ordinary people without professional training can tell which ones are people and which ones are vehicles. Not to mention the professionally trained warrior, he found that the recognition was faster and more accurate.
Of course, people also have limitations, because it is difficult for people to identify vehicles and people that are hidden and camouflaged.
So at this time, we need to rely on the power of the device. But how to let the device or system determine the target's identity and carry out selective attacks? This is also a problem they have to solve.
The first is the identification of people. At present, the identification of people mainly comes from infrared detection, radar detection, audio detection, and video pattern detection.
Not all of these technologies were first used in the military, but many were actually used in humanitarian relief. But they were later absorbed and improved from each other, and then served these two seemingly contradictory areas.
Yes, it is a contradiction. When applied to the military field, these technologies are used to discover and then destroy the enemy.
By using the search and rescue field, we can search and find those buried and trapped people, thereby saving their lives.
So in the final analysis, there is nothing wrong with technology. What is wrong is how it is used and the people who use it.
Looking back, to put it bluntly, these technologies use people's physiological signs to detect and identify personnel targets.
For example, infrared detection uses the principle that any object will produce infrared radiation as long as its temperature is above absolute zero to detect and identify people.
Although there are many objects with infrared radiation characteristics in the world, the infrared radiation characteristics of the human body are different from those of the surrounding environment. The infrared life detector uses the difference between them to separate the target to be searched from the background in the form of imaging.
This is what we often call thermal imaging cameras, which are widely used in the military. The principles and techniques are actually not complicated.
Radar detection is based on the reflection principle of electromagnetic waves. By detecting various micro-movements caused by human life activities, it can obtain relevant information about breathing and heartbeat from these micro-movements, thereby identifying the presence or absence of life.
Compared with infrared detection, the active detection method of radar makes it less susceptible to factors such as temperature, humidity, noise, and on-site terrain. The continuous emission mechanism of electromagnetic signals further increases its regional detection function. Therefore, this technology also greatly fills in the shortcomings of infrared detection.
As for audio detection, it is not commonly used in the military field. It mainly detects human heartbeat, breathing, and subtle movements by listening to subtle sounds to determine whether there are signs of life underground.
But on a battlefield with a relatively noisy environment, this technology is basically useless, so I don’t think too much about it.
Video graphics detection is actually also about judging graphics in video images. Thereby identifying which ones are people, which ones are objects, which ones are vehicles, etc. In addition, this technology can mainly be used to identify vehicle and mortar positions and ammunition piles.
Therefore, in terms of detection and recognition technology, there are actually not many obstacles. It's just that it's a big problem to integrate all the previous technologies into a small drone with limited size, limited load, and limited power, and let them operate together.
If nothing else, the size and weight of these devices on the market are enough to give them a headache.
In the small conference room in the third-floor laboratory, Wu Haozheng, Yang Fan and several technicians were smoking cigarettes, frowning and thinking about the problem.
The ashtray was almost full of cigarette butts and the smoke filling the small conference room indicated that this meeting had been going on for a long time.
"I still have the same opinion, focusing on radar detection and supplemented by laser ranging. In this way, our detection response time will be much faster, which will help us quickly find obstacles, and handle and correct the direction in time to avoid obstacles." Yang Fan He pressed the cigarette butt into the ashtray and said firmly to everyone.
After Yang Fan finished speaking, everyone nodded. As a young man wearing glasses, he shook his head and said: "I still reserve my opinion. Image recognition is definitely a very potential technology. If we can use it, not only can we solve obstacles and routes It can also play a role in the discovery and identification of targets. In this way, it can save us a lot of space and load. "
This person's name is Pang Yifei, a Ph.D. from Huada University. He has high insights in dynamic perception and information processing technology. Lin Jianliang specially poached it from a certain research institution, and it can be said that it took a lot of effort.
Although this person joined not long ago, he played a very important role in some aspects. For this reason, Wu Hao admired him very much and asked him to participate in the research and development of the core system.
This time, Pang Yifei and Yang Fan, two usually good friends, had disagreements about the dynamic sensing technology of drones, and neither one gave in.
"Radar detection is also possible." Yang Fan said tit for tat.
Pang Yifei shook his head and said: "It's just possible, but image recognition technology can do better."
