Abstract:

In view of the transition state of intermediate and terminal guidance of interceptor, the capture region of interceptor under the condition of finite overload with realistic true proportional navigation and the influencing factors of the capture region are analyzed. Firstly, the rotation coordinate system of the line of sight is introduced, and the relative motion model of the interceptor and the target in the terminal guidance section is established. Secondly, it analyzes the performance of the three dimensional (3D) realistic true proportional guidance law is analyzed, and the Lyapunov stability of the line-of-sight rotation angular velocity is judged. Then, under the conditions of the 3D realistic true proportional guidance law, the interceptor with limited overload intercepts the 3D maneuvering target, and the capture area is deduced and proved to obtain the necessary conditions for successful capture. Finally, through simulation experiments in three situations, the effectiveness of the capture area in this paper is verified, and on this basis, the influencing factors of the capture area are analyzed.

Key words: capture area, realistic true proportional guidance law, Lyapunov stability, limited overload, three-dimensional maneuver
