Optimal Cooperative Interception Method Based on the Pursuit-Evasion Problem for Multiple Missiles

In this paper, an optimal cooperative interception method based on fuze-warhead matching model and virtual force method is proposed to solve the pursuit-evasion problem of multi-missile differential cooperative interception. Firstly, the condition of successful interception is extended on the based on the traditional pursuit-evasion problem, and the damage efficiency function is established to measure the damage degree of the evader. Secondly, the interception strategy is designed by combining the idea of optimal control with virtual force method to ensure the maximum interception efficiency. Thirdly, the adaptive gain of pursuer strategy is designed based on the idea of guidance integrated fuzing so as to make full use of the information of guidance system and fuze and achieve maximum damage efficiency. Finally, the effectiveness of the proposed strategy is verified by numerical simulation.
