In order to solve the possible collision problem in Skirts the process of sub-interceptors intercepting UAV cluster, this paper proposes a collision avoidance pure proportional guidance law (CA-PPN) by combining the virtual repulsion force with the pure proportional guidance law.Firstly, it proposes an operational concept of submunition missile intercepting UAV cluster, and analyzes the guidance problem of sub-interceptors.Then, aiming at the possible collision problem in the guidance of sub-interceptors, it designs an artificial potential field for collision avoidance between sub-interceptors, and analyzes the characteristics of PPN.
On this basis, combining PPN with the virtual repulsion force in the artificial potential field, and adding the field of D Cell Ni-Cd and Ni-Mh Batteries and Battery Packs view angle and overload constraints, the CA-PPN is proposed.The simulation results show that CA-PPN can effectively intercept the target and avoid the collision between sub-interceptors.
