Dynamic Encirclement Angle-Based Cooperative Guidance Law for Multi-Missile System Against Maneuvering Target

In this paper, a novel cooperative encirclement guidance method is proposed for multiple missiles against the maneuvering target. By covering the target's reachable domain with the missiles' combined detection range, the ideal missile number and dynamic encirclement angles are designed to improve the capture probability and block escape directions of the target. Moreover, the desired positions of missiles are calculated in real-time within the leader-follower framework. Then, considering the non-adjustability of speed, a cooperative guidance law is constructed without chattering based on the continuous finite-time stabilizing control scheme to eliminate tracking errors. The finite-time stability of the system is proved theoretically. Finally, the effectiveness and feasibility are verified by numerical simulation under the constraint of balanced maneuverability.
