Research on Terminal Guidance Control of a Certain Type of Suicide Drone

The research and development of suicide drones have been summarized, such as loitering munition. Firstly, the control method of loitering munition for ground attack was studied, and in order to increase the destructive effect and hitting accuracy, a guidance law with terminal angle constraint for ground attack was designed based on the proportional navigation method after comprehensive comparison. Subsequently, longitudinal and lateral acceleration commands were derived based on the three-dimensional proportional navigation method, and the control law for the attack phase was designed. Finally, the analysis of the simulation results shows that, compared with the traditional proportional navigation method, this method can improve the accuracy of the drone's ground attack while controlling its longitudinal striking angle.
