主　　题：Active defense Ballistic missile Differential game Guidance law Optimal guidance 

摘      要：The optimal guidance problem for an interceptor against a ballistic missile with active defense is investigated in this paper.A class of optimal guidance schemes are proposed based on linear quadratic differential game method and numerical solution of Riccati differential *** choosing proper parameters, the proposed guidance schemes are able to drive the interceptor to the target and away from the defender ***, fuel cost, control saturation,chattering phenomenon and parameters selection were taken into *** of the proposed guidance schemes of the saddle point condition is proven ***, nonlinear numerical examples are included to demonstrate the effectiveness and performance of the developed guidance *** of control performance between different guidance schemes are presented and analysis.
