高速目标分阶段博弈拦截制导策略

Interception of the air-breathing hypersonic vehicle is studied based on the staged game model in this paper. The solution based on the interception system made of two interceptors are proposed. According to the maneuvering characteristics of the hypersonic target, the process of interception is divided into two stages. In the first stage, the interception system calculates the target?s reachable range and virtual interception point in the predicted intersection plane according to the target's motion characteristics and constraint conditions. Interceptor I executes mid-guidance based on the virtual handover point, and terminal guidance based on the generalized terminal guidance law. Because the movement of the target is restricted by the constraints, the feasible range and maneuvering ability of the target are greatly weakened in the penetration process. In the second stage of the interception process, the Interceptor ll-target intuitionistic fuzzy game model is established based on the game theory and the intuitionistic fuzzy theory. The equilibrium strategy model is obtained through interceptor-target strategy sets and the multi-attribute evaluation model. Our side wins the game by solving the nonlinear programming problem. Finally, the numerical results of the dynamic strategy and the fixed strategy are compared to show the effectiveness of the proposed guidance strategy.
