Research on Cooperative Head-Puruit Guidance Laws Based on Topology of “Leader-Follower”

For the purpose of improving the success rate of head-puruit guidance, cooperative head-pursuit guidance for multiple-interceptors is studied. The mode of “leader-follower” is introduced and the problem of time consistency is transformed into position consistency. A backstepping sliding mode method based head-pursuit guidance law is proposed for the “leader”, and the cooperative guidance strategies of “followers” are designed to track the “leader” trajectory. On this basis, backstepping sliding mode guidance laws for “followers” are proposed, which can complete the cooperative head-pursuit guidance for the multiple-interceptor. The validity and effectiveness of the cooperative head-pursuit guidance laws designed are verified according to the simulation results in this paper.
