在弹道导弹末段防御中,探测系统对目标识别跟踪并引导拦截系统对其拦截。为研究探测误差和探测距离对拦截弹脱靶量的影响,确定成功拦截时探测能力应满足的条件,首先,对末段防御系统的作战流程进行介绍,对动能杀伤器末段飞行进行建模,引入线性交会模型,并对导引头测量值进行卡尔曼滤波处理。通过仿真得到了探测能力与脱靶量之间的关系,给出了成功拦截时系统探测能力的约束条件。

Detection system identified and tracked the target and guided the interception system to achieve the interception of the target in the final defense of ballistic missile. In order to research the influence of detection error and detection distance on miss distance of interceptor and determine the conditions to be met when successful interception, firstly, the operation process of THAAD anti-missile system was introduced, then terminal flight model of kinetic killer was established. The relationship between the detection ability and miss distance was derived through simulation and the constraint condition of system detection ability when intercepted successfully was given.
