Analysis of current situation and development suggestions for UAV countermeasures against potential safety hazards

Due to the development of the market, drones are easy to obtain, and the phenomenon of "black flying" occurs frequently. The control of no-fly areas has always been a problem. If a drone breaks into the airport, it will directly endanger personnel safety, normal operation of the airport and economic benefits.

Along with this, drone countermeasures technology has developed rapidly, but there are a lot of irregularities or abuses, which may sometimes cause serious secondary disasters. So, how should the security risks of drone countermeasures be solved?

Overview and difficulties of UAV countermeasures technology

Drone countermeasures technology is designed to protect important areas, important airspace and important people. It is a technology that can effectively control illegally invading drones.

UAV countermeasures technology can be divided into active and passive ones. The working principle is mainly to intercept and interfere with UAVs by sensing, transmitting and processing information. The equipment detects drones through radar, radio and other sensing technologies, and then intercepts and interferes with the drones through radio interference, electromagnetic pulse and other means, and finally controls its flight trajectory.

The main types of countermeasure techniques are as follows:

01. Signal interference technology

Signal interference technology is based on the principle of UAV communication, using electromagnetic waves, sound waves and other methods to interfere with the UAV's communication or hardware, forcing the UAV to automatically return or land automatically, including navigation signal interference, electromagnetic interference, acoustic wave interference, etc. drone jammer

02. Directly destroy technology

Destruction technology is to directly destroy the target drone. It is usually used in areas with high security and privacy factors to avoid adverse consequences. It includes "hard kill" of direct destruction and "soft kill" of interference blocking. .

03. Interception and capture technology

The method is to intercept and capture from the ground or air to avoid damage to the target drone. A common one is to use a launch gun to eject the capture net, but the distance is limited.

04. Signal spoofing technology

Signal spoofing technology is to crack the data link of the target drone and transmit the packaged false signal to the target, so that it receives wrong information. Spoofing technology is mainly divided into two types, namely control signal spoofing and positioning signal spoofing.
