What are the countermeasures against drones? The core technology of anti-drone system is critical

Drones are indeed a double-edged sword in modern life. Although drones have strong advantages in surveying, mapping, photography and other fields, drone equipment carrying ammunition can cause fatal harm. Therefore, countering drones Its something that shouldnt be underestimated. However, in order to counteract drone equipment, identifying and discovering drone equipment is the key. Only when drone equipment is identified can measures be taken to suppress it. There are many types of drones now, and the technologies are also diverse. There are still many technical difficulties in countering drone equipment. For example, electromagnetic interference drone equipment also has limitations. When detecting drone equipment, high environmental requirements are required. If the environmental conditions are not met, it will be difficult to detect the drone. Although the laser anti-drone system countermeasures can quickly destroy drone equipment, falling drones will also cause ground hazards. There are also restrictions on radio interference, and it can only be suitable for drones that crack the protocol, so the difficulty is still quite high.

The first step to counter UAV equipment is to detect and discover UAV equipment. In terms of UAV detection, discovery and identification, it is a comprehensive and multi-disciplinary application technology. In implementation, radar detection, radio signal detection, photoelectric identification and other means are generally used. With the help of these advanced means, UAV equipment can be detected, identified and tracked in a timely manner. After using these means to detect UAV equipment, it can Only by discovering the intruding drone equipment in time can we take countermeasures and reduce the harm of the intruding drone equipment. In terms of radar detection, radar systems are generally used to emit electromagnetic waves, and the UAV equipment itself will produce a certain reflection effect. With this principle, UAVs can be monitored and positioned, and the reflected radar waves can be analyzed to easily detect Information such as the position and distance, orientation and altitude of the drone. UAV equipment is characterized by its small size and slow speed. It is indeed difficult to detect UAV equipment using traditional radar, and it may even be impossible to detect UAV equipment. New drone detection radars developed in recent years have signal processing and ground clutter suppression effects to improve the radar's recognition effect.

Generally speaking, during the flight of UAV equipment, the flight control system and image transmission system emit wavelengths of a certain frequency. Radio signal monitoring produces good results for UAV equipment through spectrum analysis of flight control signals and image transmission signals. Detection and identification effects. Detect intruding drone devices promptly. It can even discover the location information of drone equipment. The distance of the drone is calculated with the help of the received signal. This information can be used to accurately identify and warn the drone equipment, so that measures can be taken in advance.
