Embodiment Construction
[0059] The purpose of the present invention is to overcome the shortcoming of above-mentioned prior art, research a kind of unmanned aerial vehicle (Unmanned AerialVehicle, UAV) as the wireless communication eavesdropping scheme of legal wiretapping device UAV (E), in this scheme, a legal wiretapping device ( A UAV(E)) is used to eavesdrop on suspicious messages sent by a suspicious transmitter (UAV(B)) to a suspicious receiver on the ground. Using the characteristics of suspicious systems, an effective active jamming scheme is proposed to maximize the eavesdropping rate.
[0060] Please refer to figure 1 , the embodiment of the present invention discloses a UAV active eavesdropping method for joint trajectory and interference power optimization, including:
[0061] Step 10. In the UAV active eavesdropping model, set the initial trajectory of the suspicious transmitter respectively The initial transmission power P of the suspicious transmitter B , the initial trajectory of...
