摘　　要：弹道导弹末段防御系统包括探测系统与拦截系统,探测系统为拦截系统提供目标状态信息。从拦截脱靶量以及燃料消耗两个方面研究探测系统的探测误差对拦截系统拦截效果的影响。在系统分析了末段拦截系统的探测误差及弹目运动规律的基础上,建立了基于比例导引法的末段拦截系统模型,将无迹卡尔曼滤波引入模型中对状态变量进行滤波处理。通过改变探测误差的大小研究探测误差与脱靶量和燃料消耗之间的关系,给出了成功拦截时雷达探测误差与导引头探测误差应满足的条件。The terminal ballistic missile defense system includes the detection system and the interception system. The detection system provides the target state information for the interception system. The influence of detection error on the intercepting effect is studied form both miss distance and fuel consumption. Based on the analysis of detection error in the terminal interception system and motion law of kinetic killer and target, a terminal interception system model based on proportional guidance is set up. The unscented kalman filter is introduced to filter the state variables in the model. The relationship between the detection error and miss distance and interception energy are analyzed through changing the detection error size. The constraint conditions for radar and seeker detection error when successful interception is given.
