Ground Target Guidance Method for Oriented Overhead Tracking of Fixed-Wing UAV

In order to realize the close and automatic tracking of ground targets by fixed-wing UAV, a directional overhead tracking ground target guidance method for fixed-wing UAV is proposed. By establishing the mathematical model of fixed-wing UAV directional overhead tracking ground target and analyzing its motion relationship, the guidance law of fixed-wing UAV directional overhead tracking ground target is designed based on the Dubins model of UAV, and the simulation validation is carried out for different moving ground targets. The simulation results show that the guidance method can realize the directional overhead tracking of fixed-wing UAV to ground targets in different motion states, and has good tracking performance.
