A method of controlling impact time and impact angle of multiple-missiles cooperative combat

To improve the penetration ability and precisely hitting capacity of multiple-missiles, a method of controlling the impact time and impact angle of missiles was proposed. One of the missiles was regarded as leader, and a fictitious sphere was built. The center of the fictitious sphere was the target, and the radius was the distance between the leader and target. Above the sphere, a fictitious dot corresponding to a follower was determined according to the desired impact angle of the follower. The relative motion model of the follower and fictitious dot was built. Based on the optimal control theory, a state regulator was designed, which controlled the follower to approach and track the fictitious dot, and the cooperation of missiles on impact time and impact angle was realized. To reduce the required overload of the follower, the improvement design of the fictitious dot track was carried out. Simulation results show the effectiveness of the control method and improvement design of the fictitious dot track.
