Of course, this is only about the technical difficulties of the drone flying at high speeds and crossing obstacles.

If this drone can quickly find the target and identify the target to attack the target, this is also a technical problem that needs to be solved urgently.

If you want to solve this problem, you must first figure out what targets their 'Battlefield Sweeper' high-speed small attack drone swarm strike system is used for.

First of all, the main target is definitely to target the enemy soldiers in non-enclosed environments, which is the main target of this strike weapon.

Then 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 charge, and it certainly can't.

But if a special design is made in the charge of the drone so that it can explode in a forward direction. Multiple UAVs form an attack team to continuously attack a point of the target in a short period of time, and the high-pressure metal jet generated by directional blasting will also cause a breakdown effect on the thin body of the vehicle.

This principle is a bit like some armor-piercing bullets with a tandem charge or a ground-penetrating projectile with a tandem charge. In the face of ultra-high-strength armor or ultra-thick concrete bunkers, armor-piercing and ground-penetrating shells use this kind of chain blasting to relax and progress, until they penetrate the protective armor and reach the inside of the target.

If the task of detecting and identifying is left to people, it will certainly be fine. Even ordinary people who are not professionally trained can tell which ones are people and which ones are vehicles. And not to mention the professionally trained fighter, who found the identification faster and more accurate.

Of course, people also have limitations, because it is difficult for people to identify vehicles and people who are hiding and camouflaged.

So at this time, it is necessary to use the power of the device, but how to let the device or the system judge the target identity and carry out selective attacks, which is also a problem they have to solve.

The first is the identification of personnel, which is mainly derived from infrared detection, radar detection, audio detection, and video pattern detection.

Not all of these technologies were first used in the military, and many were actually used for humanitarian relief. It's just that they are then absorbed and improved by each other, and then serve these two seemingly contradictory areas.

That's right, it's a contradiction. In the military field, these techniques are designed to detect the enemy and then destroy it.

The search and rescue field can be used to search for trapped people who are buried, thereby saving their lives.

So at the end of the day, there's nothing wrong with technology, it's just how it's used and the people who use it.

In retrospect, to put it bluntly, these technologies use the physiological signs of the human body to detect and identify personnel targets.

For example, infrared detection is to use the principle that any object will produce infrared radiation as long as the temperature is above absolute zero to detect and identify personnel.

Although there are many objects in the world that have infrared radiation characteristics, the infrared radiation characteristics of the human body are different from the infrared radiation characteristics of the surrounding environment. Infrared life detectors use the differences between them to separate the target from the background in an imaging way.

This is what we often call a thermal imager, which has been widely used in the military, and the principle and technology are not complicated.

Radar detection, on the other hand, is made by using the principle of reflection of electromagnetic waves, by detecting various micro-movements caused by human life activities, and obtaining relevant information about breathing and heartbeat from these micro-movements, so as to identify whether there is life.

Compared with infrared detection, the active detection method of radar makes it less susceptible to the influence of temperature, humidity, noise, on-site terrain and other factors, and the continuous emission mechanism of electromagnetic signals increases its regional detection function. Therefore, this technology also greatly fills the shortcomings of infrared detection.

As for audio detection, it is not commonly used in the military field, it is mainly by listening to subtle sounds to detect people's heartbeat, breathing, and subtle movements to determine whether there are signs of life underground.

It's just that on the battlefield with a noisy environment, this technology is basically useless, so I don't think too much about it.

Video pattern detection is actually to judge the graphics in the video image. Thus identifying those are people, those are objects, those are vehicles, and so on. In addition, for vehicle and mortar positions, the identification of ammunition piles is mainly based on this technology.

Therefore, in terms of detection and recognition technology, there is actually not much obstacle. It's just that it is a big problem to concentrate the previous technologies on a small UAV with limited volume, limited load and limited power, and let them operate comprehensively.

Not to mention anything else, let's just say that the size and weight of these devices on the market are enough for them to have a headache.

In the small conference room in the laboratory on the third floor, Wu Hao was smoking cigarettes with Yang Fan and several technicians, frowning and thinking about the question.

The cigarette butts that were already piling up in the ashtray and the smoke in the small conference room were a sign that the meeting had been going on for a long time.

"I still have that opinion, mainly radar detection, supplemented by laser ranging. In this way, our detection response time is much faster, which is conducive to us to quickly find obstacles, and timely deal with and trim the direction to avoid obstacles. Yang Fan pressed the cigarette butt into the ashtray and said firmly to everyone.

After Yang Fan's words were finished, everyone nodded. Only as a young man with glasses shook his head and said: "I still have reservations, image recognition is definitely a very potential technology." If we can use it, we can not only solve the problem of obstacle and route detection, but also play a role in the detection and identification of targets. In this way, we can save a lot of space and load. ”

This person's name is Pang Yifei, Ph.D. Huada, and he has a high insight in dynamic perception and information processing technology. It was Lin Jianliang who specially dug it from a certain research institution, and it can be said that it took a lot of effort.

Although this person has not been in for a long time, he has played a very important role in some aspects. Therefore, Wu Hao admired him very much and let him participate in the research and development of the core system.

This time, in terms of the dynamic perception technology of drones, Pang Yifei and Yang Fan, two friends who usually have a good relationship, had a disagreement, and no one gave in.

"Radar detection is fine." Yang Fan said-for-tat.

Pang Yifei shook his head and said: "It's just okay, and image recognition technology can do better." ”

"You ......"
