With the rapid development of modern science and technology, UAV has entered people's ordinary life. Various UAVs have been used in many fields. But if the UAV appears in the wrong position, in order to prevent bad things from happening. We must take effective measures to control it. Therefore, UAV countermeasure equipment is to use scientific and technological means to carry out UAV defense.

At present, UAV is mainly controlled by radio communication technology. Therefore, by sending high-performance interference signals to the target UAV and suppressing the control signals, the normal use of the UAV can be effectively interfered to make the UAV land or return forcibly. UAV reaction equipment is installed on the equipment rack. By sending a complete interference signal to the UAV, the UAV leaves the control of the operator and lands automatically without receiving the control signal. After the UAV is found and located accurately, it must be intercepted effectively, which is usually used for signal interference. The directional radio frequency emitted by the UAV reaction equipment mainly to the target UAV can effectively cut off the communication between the UAV and the remote controller and force the UAV to land or leave safely.

Now, the national low altitude airspace has been opened, and many applications of UAVs and other related aspects have also increased. Due to the abuse of UAVs by bad manufacturers, accidents caused by "black flight" of UAVs have become common. Therefore, it has become a top priority to comprehensively strengthen the protection of social areas.
