How Anti-UAV System Strikes Black Fly?

How Anti-UAV System Strikes Black Fly?

  • 2022/08/26

The main purpose of the UAV jammer is to reduce illegal penetration or to monitor potential security problems associated with large-scale activities. With the development of the UAV industry, the UAV's universal availability and simplicity of operation are applied to daily life, which brings about greater security risks to social order. For example: transport dangerous prohibited objects to the site, and take photos in some private places. All these operations can be done with unmanned aerial vehicles. Now UAV has good cargo carrying capacity, so it is important to pay attention to prevention and control.

The unmanned aerial vehicle (UAV) and video transmission channel are suppressed by the control signal of the UAV, and the active protection for the "black flight" UAV is achieved mainly by interfering with the GPS satellite signal. When the UAV interferer is in use, it is very likely that the UAV will be lost during data transmission such as video images, and to prevent further UAV flight into protected areas. When the UAV loses contact with the operator and the GPS signal, it will automatically return until the battery is exhausted. Within the operating range of the UAV, radio frequency signals force the UAV's operators to stop flying near the system-equipped facilities to prevent damage from the UAV. This local law against unmanned aerial vehicle "black flight" minimizes the risk of human private property.

Therefore, in the anti-UAV system, the anti-jamming system of the UAV needs the support of the multi-band electromagnetic interference technology of the UAV. Generally, in the process of fighting UAV, signal blocking and other technologies are used, that is, UAV electromagnetic interference. This interference mode sends directional radio frequency and sound waves to the Black Fly UAV in the UAV response system, interferes with or cuts off the communication between the UAV and the remote control, and forces the Black Fly UAV to leave by itself.
