基于末段修正迫弹命中概率的射角优化

摘要

To improve the hit probability of semi-active laser Terminal Correction Mortar Proj ectile(TCMP ),the scheme of optimizing launching angle was proposed.The laser-seeker target-acquisition-probability model and hit-probability model were established.By taking the launching angle as the optimal variable and taking the hit probability and average impact point de-viation as obj ective functions,the optimum launching-angle was solved by the efficacy coefficient method.The Monte-Carlo method was applied to simulating shooting and calculation,and the result after optimization were compared with that before optimization.The results show that the scheme of optimizing launching angle can improve the hit probability of TCMP by 10%,and it has important significance to the firing table compilation of semi-active laser TCMP.%为提高激光半主动末段修正迫弹的命中概率，提出了优化发射角的方案。建立了激光导引头目标捕获概率模型和命中概率模型，以发射角为优化变量，以命中概率和平均落点偏差为目标函数，采用功效系数法求出最优射角。通过蒙特卡洛法进行模拟打靶和仿真计算，将优化前后的结果进行对比。分析结果表明，优化射角的方案可使末修迫弹命中概率提高10%以上，对激光半主动末段修正弹的射表编制具有重要意义。
