制导精度对弹道导弹动能拦截效果的影响分析

本文首先从碰撞几何关系角度建立了直接碰撞毁伤来袭弹头内所有子弹头的碰撞毁伤模型，并得出了碰撞弹坑需求；其次从碰撞能量角度建立了直接碰撞产生的动能与对弹头造成侵彻弹坑的关系。通过仿真计算，得到了碰撞精度与弹目交汇速度、KKV的质量和体积之间的关系，可为KKV的设计提供参考。

Analysis of the effect of guidance accuracy on balastic missile hit-to-kill ability

Firstly,based on the collision geometry, a collision damage model ofdirect impact to damage all the warheads in the incoming missiles is established, and the demands of collision crater are estimated. Secondly, from the perspective of collision energy, the relationship between the kinetic energy from direct impact and the craters on the warhead is set up.Simulation results shows that the relationship between the accuracy of collision and velocity in the meeting model of target and missile, the mass of KKV and the volume of KKV. Thus it is possible to provide reference for the design of KKV.
