摘要
以卫星/激光半主动复合制导迫弹弹道建模为背景,提供制导弹药修正能力分析的一般思路和方法,分析了制导迫弹的制导原理,建立了舵偏角转换关系。在建立弹道模型的基础上,重点分析了制导段最大修正能力,激光导引头最大有效距离的精度需求及影响修正能力的主要因素。仿真研究结果表明,制导迫弹的修正能力均大于全弹道及激光制导段的落点散布范围,能够满足修正需求。同时,舵偏角、起控时间等均对修正能力产生影响。
Based on establishing trajectory modeling of the satellite / semi-active laser guided mortar,general method of analyzing the correction capability of guided ammunition is offered. The guidance principle of mortar is analyzed,and the transformation angle relation of control surface is modeled. The largest correction capability of the trajectory in guided section,the laser guidance requirement and the main factors of impacting on correction capability are analyzed. The results of simulation and study show that,the demand could be contented,and the range of the whole trajectory and laser guidance section is included in the correction capability range of guided mortar. The correction capability is effected by the angle of control surface,the time of starting control,etc.
