Control of impact angle can considerably increase interceptor's lethality in terminal engagement. A differential game guidance law was proposed in this paper, which can achieve a specified impact angle as well as zero terminal miss distance. The adversaries in conflict were considered as two independent controlled objects, through minimizing the cost function, one can obtain the adversary's optimal maneuver strategy simultaneously. Simulation results show that the proposed guidance law is suitable for intercepting high-speed maneuvering target., and, centimeter level miss distance requires less guidance command to avoid command saturation near terminal time.
