摘　　要：基于给定的制导工具误差模型,运用蒙特卡罗方法进行弹道仿真计算,得到了关于导弹的落点偏差信息,在此基础上分析了工具误差系数对导弹落点精度的影响,同时给出了几种小样本情况下导弹命中精度的估计方法,并采用有效性的度量指标比较了几种方法的准确性,给出了一些有益的结论。The data of the fall point deviation of missiles were obtained by utilizing Monte Carlo ballistic simulation method based on the given guidance instrument error model. According to the simulation data, the paper analysis that how the guidance instrument error affect the shot accuracy of the missile, then six methods of precision assessment for small samples were put forward and compared with the others by using measures of effectiveness, some helpful conclusions were presented at the end of the paper.
