Secure Cooperative Guidance Strategy for Multimissile System With Collision Avoidance

Abstract

Secure cooperative guidance problems are investigated, where secure mechanisms have been introduced to the cooperative guidance structure. First, the desired attack angle-based interception is designed for the leader missile to provide a fine reference trajectory. Second, the secure mechanisms are proposed for follower missiles by employing modified artificial potential field (MAPF) method, where each follower missile can maintain the minimum safe distances with neighboring threats. The secure cooperative guidance laws are proposed with repulsive forces obtained by the MAPF method. Third, the cooperative interception equivalent verification system is constructed on the base of multiple mobile robots. Finally, both the simulation and experiments examples show the fine practical performance for the secure strategy.
