摘　　要：为了得到某型弹道修正弹的落点散布规律和射击精度评定方法,以蒙特卡洛打靶获取的落点数据为基础,通过基本的数值统计分析、直方图法、概率纸法、偏度峰度法以及SPSS软件分析等方法,对修正弹落点散布情况进行统计分析,确定了其散布服从二维正态分布,得到了相应的概率密度函数,对比了修正弹与无控弹的射击精度。结果表明,弹道修正弹射击精度的评定可以采用与无控弹同样的指标和计算方法,为修正弹项目验收的射击精度评定部分以及后续的作战使用提供了理论和技术支撑。In order to obtain the dispersion law of impact points and the evaluation method of firing accuracy for a certain type of trajectory correction projectile,lots of impact-point data of trajectory correction projectile was obtained through the Monte-Carlo target practice.The distribution law of impact points was analyzed by using classical numerical statistics,histogram,probability paper,skewness kurtosis testing and SPSS software.It was determined that the dispersion of impact points obeys the two-dimensional normal distribution,and the probability density function was also obtained.The firing accuracy of the trajectory correction projectile was compared with that of uncontrolled projectile.The result shows that the index and calculation method of uncontrolled projectile are suitable for evaluating the firing accuracy of trajectory correction projectile.It provides theoretical and technical support for the acceptance of firing accuracy of trajectory correction projectile,and it’s also helpful for the application of the ammunition in future war.
