Active monitoring method and system based on signal interference technology in unmanned aerial vehicle communication

The invention discloses an active monitoring method and system based on the signal interference technology in unmanned aerial vehicle communication. The method comprises the following steps: step S1,transmitting an interference signal to a suspicious unmanned aerial vehicle signal receiving end through an interference link to change the signal-to-noise ratio of a suspicious communication link; and step S2, while transmitting the interference signal, monitoring a data packet in the suspicious link. According to the active monitoring method and system disclosed by the invention, a legal unmanned aerial vehicle can perform signal interference and monitoring on the suspicious unmanned aerial vehicle at the lowest power consumption based on the signal interference technology, and the optimal monitoring effect is achieved. 本发明公开了种无人机通信中基于信号干扰技术的主动侦听方法及系统，包括如下步骤：步骤S1，通过干扰链路向可疑无人机信号接收端发送干扰信号，以改变可疑通信链路的信噪比；步骤S2，在发射干扰信号的同时，侦听可疑链路中的数据包，本发明基于信号干扰技术可令合法无人机能够以最低功耗对可疑无人机进行信号干扰和侦听，达到最佳侦听效果。
