Anti-drone technical means

With the maturity of UAV-related technologies, its use in work and life is becoming more and more extensive. At present, civilian drones are widely used in emergency rescue, environmental monitoring, power line patrol, aerial photography mapping, agricultural plant protection and other fields. However, the flight and use of UAVs need to be carried out within a reasonable and legal range. Disorderly flight and illegal flight will not only interfere with the normal operation of military and civilian aircraft, but also may lead to flight accidents, resulting in serious consequences and serious consequences for the country. and loss of life and property of the people. Therefore, anti-drone equipment has been derived, which can effectively control black illegal and illegal flying.

At present, anti-UAV systems at home and abroad mainly use three methods to counteract them.

1. Signal interference blocking type (cost-effective, widely used) Texin Electronics has 10 years of professional experience

①Wireless electromagnetic wave interference: By cutting off the UAV's remote control signal, data transmission, and image transmission signal (mainly 2.4G/5.8G for civil aircraft), the UAV will enter a self-protection state after signal loss, reaching The purpose of the forced landing or expulsion of the drone. drone jammer

②GPS Navigation and Positioning Interference: UAVs generally use satellite navigation and positioning systems to locate their own positions, and interference to UAVs can be achieved by blocking GPS signals. At this time, after the UAV loses the GPS signal, it cannot be accurately positioned and will enter a self-protection state to achieve the purpose of forced landing or driving away of the UAV.

2. Weapon attack (not feasible in the civilian field)

Use weapons to carry out directional attacks on UAVs to achieve the purpose of directly destroying UAVs. However, this method requires high aiming accuracy, high cost, and associated losses due to the fall of the UAV. Therefore, the method of directly destroying the UAV is almost unfeasible in the civilian field.

3. Intercept network capture class (difficult to operate)

A final countermeasure is to launch interceptor nets from the ground or from the air to capture drones. The main methods include: capture net, drone capture, etc. It is commonly used to eject the capture net from the launch gun, but this method can only be implemented at close range to the drone, and the accuracy requirements are relatively high. There is also the use of large drones to capture small drones, and the use of large drones to capture small drones with a giant capture net mounted below. However, this method is very difficult to control, and small UAVs are more flexible in terms of flexibility, so they are not widely used.
