过载约束下的大机动目标协同拦截

In this paper, the cooperative interception of multiple inferior missiles with acceleration constraints to intercept a highly maneuvering target is studied using the nonlinear interception geometry. Firstly, based on the establishment of the reachable region of the missile, the feasible region of the missile, and the escape region of the target, a cooperative interception strategy based on the coverage of escape region using nonlinear interception geometry and a design method based on the standard trajectory are proposed. Secondly, after giving the form of co-operative guidance law, the relationship between the initial position of the terminal guidance phase, the parameters of the guidance law, and the coverage area of the maneuvering range of the target is studied. A numerical algorithm is designed to realize the allocation of the coverage area, the design of the cooperative guidance law, and the configuration of the initial interception position. Finally, the theoretical results are simulated. The results show that multiple missiles with weak maneuverability can intercept highly maneuvering target through a reasonable configuration of the initial interception position and a reasonable design of parameters in the cooperative guidance law.
