导引头性能对拦截战术弹道导弹制导精度的影响

针对末制段采用直接碰撞动能杀伤技术的拦截弹拦截战术弹道导弹（TBM），分析了导引头分辨率、帧频和测量噪声等主要性能参数对制导精度的影响。在拦截弹弹道修正和姿态控制规律的基础上，考虑拦截弹与TBM的初始位置偏差，弹道修正发动机推力偏差和制导控制延迟因素，完成了导引头不同性能参数条件上拦截弹拦截TBM制导精度的六自由度Monte-Carlo仿真计算，根据对仿真结果的分析，给出了直接碰撞动能杀伤方式下的制导精度与导头性能参数之间的约束关系。

Effect of seeker performance on guidance accuracy for using hit-to-kill technology to intercept tactical ballistic missile

The effect of seeker performance on guidance accuracy for using hit-to-kill technology to intercept tactical ballistic missile (TBM) during terminal phase is investigated. Based on the divert and attitude control law of interceptor, error factors including initial position error of interceptor and TBM, divert control system bias of interceptor and main delay in guidance & control system are considered. Then, the guidance accuracy for using interceptor to intercept TBM is simulated on the condition of different performance parameter of the seeker. Finally, from the simulation result, it is given the constraint relation between guidance accuracy and seeker performance for using hit-to-kill technology to intercept TBM.
