Abstract

The invention provides a spectrum detection and signal suppression integrated device and a control method. The device comprises an antenna module, a radio frequency switching module which is used forswitching radio frequency signal receiving and transmitting, a signal transmitting and receiving module which is used for receiving the radio frequency signals and generating interference signals fortransmission, and a master control module. The modules are connected in sequence. When an unmanned aerial vehicle target is detected, in a time division multiplexing mode, the master control module switches and controls the signal transmitting and receiving module in turns within different time slots, to receive the radio frequency signals, and generate the suppression interference signals for transmission through utilization of the antenna module. The device and the method have the advantages that realization is simple, unmanned aerial vehicle spectrum detection and signal suppression can beintegrated, the spectrum detection and the signal suppression do not influence each other and detection and signal suppression performance is good.

Description

technical field [0001] The invention relates to the technical field of anti-drone detection, interference and control, in particular to an integrated device and control method for spectrum detection and signal suppression. Background technique [0002] The working principle of the anti-drone jammer to suppress interference is to use radio waves with the same frequency band as the drone's working frequency and higher power to cover the radio communication between the drone and the remote control, and the satellite positioning signal received by the drone. The working principle of the UAV spectrum detection equipment is to detect the radio communication between the UAV and the remote control, that is, if the UAV spectrum detection equipment and the jammer work at the same time, they will interfere with each other. The signal received by the detection equipment makes it impossible to correctly analyze the signal of the UAV, which affects the spectrum detection component and can...

Problems solved by technology

[0004] However, in the combination of the above-mentioned simple UAV spectrum detection and anti-UAV jammer, the UAV spectrum detection and anti-UAV jamming cannot work at the same time. After the UAV is detected and the jamming is turned on, the jamming signal is Continuous transmission until the interference stops, and the target detection process needs to be suspended during the transmission of interference signals, and the spectrum detection equipment is equivalent to failure, so there will be the following problems:

[0005] 1) After the jamming is turned on, it is no longer possible to obtain the position of the drone in real time, and if the drone is no longer within the effective beam range of the jammer for some reason, the system cannot adjust the direction of the jammer, which will cause the jamming to fail;

[0006] 2) After the jamming is turned on, it is impossible to judge whether the drone has left the armed area. If the drone is successfully driven away, it may be necessary to stop the jamming immediately, but because the system cannot judge whether it has been driven away, it is impossible to stop the jamming in time

[0007] Therefore, it is urgent to provide a device that can integrate UAV spectrum detection and signal suppression, which can control UAV spectrum detection and signal suppression to work at the same time, and at the same time, spectrum detection and signal suppression can not affect each other to avoid interference during work UAV Spectrum Detection
