Ship Defense Against Unmanned Aircraft Based on Forwarding Time Delay Jamming

Currently, drones pose a threat to maritime navigation of ships, and how to realize the effective defense of ships against UAV has become a problem that needs to be solved urgently. Currently, the most cost-effective means of defense is UAV jamming and deception, based on the time-delayed single- station GPS forwarding deception jamming can realize the long- distance deception of UAV, interfere with their satellite positioning, and force them to deviate from the established route. This paper addresses the problems of low correlation between the deception trajectory and the original planned route, as well as unspecified destination areas in current domestic and foreign research on static deception, one-way deception, and fluctuation curve deception. A single station UAVs synchronous deception model is designed, and a delay control algorithm for synchronous deception is proposed. Through simulation calculations, the target UAVs can be successfully lured to the designated area.
