Abstract: The optimal maneuver penetration of ballistic missiles is studied to improve their penetration capability. Through the simplification and analysis of the motion model, it is determined whether the optimal penetration direction is located in the normal plane connecting the positions of ballistic missile and exoatmospheric kill vehicle. A multi-stage first-order differential motion equation is established based on the motion models of both offensive and defensive parties. The analytical expression of the optimal ballistic missile penetration time is obtained by solving this equation. The error limit of the model parameters that the penetration strategy can support is analyzed. In order to verify the correctness of the obtained optimal penetration time and optimal penetration direction, the two-dimensional and three-dimensional engagement simulations were carried out. The simulated results show that the evading strategy of short-time large pulse maneuver in the direction of the opposite position can be used to effectively penetrate the defense and achieve the maximum miss distance.
