When the drone appears in a place where it shouldn’t, we need to control it and take effective countermeasures. Therefore, anti-UAV technology is needed to carry out drone countermeasures.
To counter UAVs, you first need to discover the UAV, locate the location of the UAV, and then counter the UAV through signal interference. There are many ways to discover UAVs, and technologies such as radar detection, radio detection, and photoelectric tracking are generally used. The radio uses frequency bands to detect the presence of drones, so even if there are obstacles, as long as the drone sends out the corresponding frequency band, it can be detected; but the radio cannot detect the silent flying drone, what is silent flight? Silent flight is generally a flight that uses navigation to set a route, so radar is needed for detection at this time; and photoelectric is actually a tracking system. When radio and radar find the UAV, it will track and lock and provide visible light for interference strike Surveillance, which is used for target detection, verification and tracking during the day or night.
At present, the frequency bands of China’s UAVs are both 1.5G and 5.8G frequency bands; while the frequency bands of imported UAVs are not the same, so anti-UAV equipment naturally needs to have multi-band signal interference technology.
After the drone is discovered and accurately positioned, it needs to be effectively attacked; the method of attacking the drone is generally to block interference, that is, signal interference. Interference blocking anti-drone equipment mainly emits directional sound waves or radio frequencies to the target drone, interfering with the drone’s hardware or cutting off the communication between the drone and the remote control, thereby forcing the drone to land safely on its own Or drive away.
