The most common interference methods for unmanned aerial vehicle countermeasures

Due to the rampant situation of drone "black flying", the "anti drone" market is gradually starting and moving towards the right track. With the advancement of technology and the continuous growth of the drone market, the hidden dangers caused by "black flying" have not been solved for a long time. The drone countermeasures system developed by the "anti drone" industry, as a specialized response to the phenomenon of "black flying" drones, has shown particularly outstanding results. Drone countermeasures typically interfere with drones through signal interference, acoustic interference, radio hijacking, and other means.

For example, GPS signal interference releases a certain power of directional radio frequency to drones, making it impossible for drones equipped with GPS positioning systems to obtain accurate coordinate data, resulting in them hovering in the air and swaying in the wind; The main target of acoustic interference is the gyroscope carried by the drone. When the frequency of the acoustic wave is consistent with its natural frequency, resonance occurs between the two sides, which in turn affects the normal operation of the gyroscope and leads to flight chaos of the drone. In severe cases, it may cause the drone to crash; Radio hijacking is achieved by interfering with the radio frequency between the drone and the controller to gain control of the drone, causing it to hover, fall directly, or return on its own.

From the current perspective, the interference methods represented by the drone countermeasures system of the interference equipment have achieved certain results in terms of overall "interference" capability.
