Military Technology

Of course, this is just about the technical difficulties of drones flying at high speeds and traversing obstacles.

Wanting this drone to quickly find the target and identify the target to attack is also a technical problem that needs to be solved urgently in front of them.

If you want to solve this problem, then you must first figure out what their 'battlefield sweeper' high-speed small attack drone swarm strike system is used to target.

First of all, the main target must be aimed at the soldiers of the enemy in a non-closed environment, which is the main target of this strike weapon.

The second is 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 UAV has a limited amount of medicine.

But if the drone's charge is specially designed so that it can explode in a forward direction. Multiple drones form an attack team to continuously attack a point of the target in a short period of time, then 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-charged armor-piercing bullets or tandem-charged penetrators. In the face of ultra-high-strength armor or ultra-thick concrete bunkers, armor-piercing projectiles and ground-penetrating projectiles use the relaxation and progression of this serial blasting until they penetrate the protective armor and reach the interior of the target.

If the task of reconnaissance discovery and identification is handed over to a human, it will be no problem. Even ordinary people who are not professionally trained can tell which are people and which are vehicles. Not to mention a professionally trained fighter, he found that the recognition was faster and more accurate.

Of course, people also have limitations, because it is difficult for people to identify those vehicles and personnel that are concealed by camouflage.

So at this time, it is necessary to use the power of the device. How can the device or the system judge the identity of the target by itself and carry out selective attacks? This is also the 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 graphics detection.

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

Yes, it is a contradiction. Applied to the military field, these technologies are to detect the enemy, and then destroy the enemy.

Using the field of search and rescue, it is possible to search and find those buried trapped people, thereby saving their lives.

So in the end, there’s nothing wrong with technology, it’s just how it’s used and who’s using it.

Looking back, to put it bluntly, these technologies use human physical signs to detect and identify personnel targets.

For example, infrared detection is to use the principle that any object will generate infrared radiation as long as the 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 the infrared radiation characteristics of the surrounding environment. The infrared life detector uses the difference between them to separate the target to be searched from the background by imaging.

This is what we often call thermal imagers, which have been widely used in the military, and the principles and technologies are actually not complicated.

As for radar detection, it is made by using the reflection principle of electromagnetic waves. It detects various micro-movements caused by human life activities, and obtains information about breathing and heartbeat from these micro-motions, thereby identifying whether there is 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 increases its regional detection function. Therefore, this technology also greatly fills the insufficiency of infrared detection.

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

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

Video graphics detection, in fact, is 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 vehicles and mortar positions, the identification of ammunition stacks can mainly use this technology.

Therefore, in terms of detection and recognition technology, there are not many obstacles. It's just that it is a big problem to concentrate all the previous technologies on a small UAV with limited volume, 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 laboratory on the third floor, Wu Haozheng, Yang Fan and a few technicians were smoking a cigarette, frowning and thinking about the problem.

The ashtrays filled with cigarette butts and the smoke in the small conference room all indicated that the meeting had been going on for a long time.

"I still have that opinion. The radar detection is the main method, and the laser ranging is supplemented. This way, our detection response time is much faster, which is helpful for us to quickly find obstacles, deal with them in time, and adjust the direction to avoid obstacles." Yang Fan Pressing the cigarette butt into the ashtray, he said firmly to the crowd.

After Yang Fan finished speaking, everyone nodded. Only as a young man wearing glasses, he shook his head and said: "I still have reservations, 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 is called Pang Yifei, Dr. Hua Da, who has a high level of insight in dynamic perception and information processing technology. It was specially dug by Lin Jianliang from a certain research institution. It can be said that it took a lot of effort.

Although this person joined in for a short time, he 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, Pang Yifei and Yang Fan, two friends who were usually good friends, had a disagreement on the dynamic perception technology of drones, and neither of them gave in.

"Radar detection is also possible." Yang Fan said tit for tat.

Pang Yifei shook his head and said, "It's only possible, but image recognition technology can do better."
