Cooperative Guidance Control with Collision Avoidance and Obstacle Dodging Mechanism

Abstract

The cooperative guidance issues for multiple missiles against a maneuvering target with collision avoidance and obstacle dodging mechanism are considered. Firstly, a fully head-on guidance law is designed by using backstepping control and trajectory shaping techniques, which provides a great reference trajectory for the leader missile. Secondly, based on the modified artificial potential field (MAPF) method, a novel collision avoidance and obstacle dodging strategies in the cooperative guidance process of follower missiles is proposed. The secure time-varying line of sight (LOS) angle formation tracking guidance law is then designed for follower missiles by using backstepping control frameworks and the repulsive force obtained by the MAPF method. Finally, two numerical simulation examples are conducted to illustrate the effectiveness of proposed secure cooperative guidance strategy.
