[0035] After receiving the signal, the spectrum analysis unit 22 analyzes it, which can identify the characteristics of the signal, such as the frequency, modulation method, signal strength variation law, etc., after completing the signal characteristic analysis, the spectrum analysis unit 22 transmits the related data to the azimuth positioning antenna array unit 23;

[0039] At the same time, the FPGA chip controls the GNSS spoofing generator 32 to generate false GPS coordinates, when the UAV relies on GPS for positioning and navigation, it will receive these false coordinate information, and then cause the positioning system to make errors, so that the UAV loses its way and deviates from the predetermined route;

[0040] For the frequency hopping suppression unit 33, the FPGA chip will control it to emit directional narrowband interference signals and wideband suppression signals at the same time, the narrowband interference signals can accurately interfere with the specific frequency band of the UAV communication, while the wideband suppression signals will generate noise in a wider frequency range, interfering with the normal work of the UAV from all directions, so that it cannot fly stably;

[0041] During the working process of the composite interference generating device module, if the ARM processor monitors the change of the UAV signal through the multi-band detection system module, such as the UAV changing the communication frequency band or the abnormal flight state, the ARM processor will adjust the interference strategy again, and send new instructions to the FPGA chip again, to ensure the continuous effectiveness of the interference work.
