制导火箭末敏弹射击精度分析

制导火箭末敏弹是火箭制导控制技术和末敏弹技术有机结合的新型弹药,针对此前制导火箭与末敏子弹相结合的系统射击精度研究不够充分的问题,根据制导火箭末敏弹的工作流程和弹道特点,建立了各飞行段制导火箭和末敏子弹的弹道模型,通过分析各弹道段扰动因素的影响,对误差源进行了分配,运用Monte-Carlo法进行了射击精度仿真计算和分析。结果表明,制导火箭末敏弹系统射击精度(CEP)不大于60 m,与末敏子弹的扫描探测范围匹配,满足精确打击小幅员目标的要求。分析方法和仿真结果对完善制导火箭末敏弹指标体系、优化弹道方案以及作战使用时计算用弹量等具有重要意义,也可作为同类装备设计参考。

Analysis of Firing Accuracy for Terminal Sensing Ammunition of Guided Rokect

The guided rocket with terminal sensing ammunition is a newly developed ammunition,and the technology of rocket guidance and controlling is integrated with terminal sensing ammunition.The firing accuracy of integrated system of the guided rocket and terminal sensing submunition is poorly studied.Aiming at this problem,the trajectory model was built for guided rocket and terminal sensing ammunition’s submunition in different flight profile according to operational procedure and ballistic features of guided rocket terminal-sensing-ammunition.The influence of disturbing factors in different flight profile was analyzed,and the error source was allocated.The firing accuracy was simulated and analyzed by Monte-Carle method.The results show that the firing accuracy(CEP)of guided rocket with terminal submunition is not more than 60 m,which matches with the detection boundary of terminal sensing submunition,and it satisfies the requirement of attacking the small group targets.The analyzing methods and calculated results are very important for perfecting the index system of guided rocket terminal-sensing-submunition,optimization of the trajectory scheme as well as calculating the consumption of rockets in operation,and it offers design reference for similar equipment.
