摘要
针对面目标打击中的水平攻击和垂直攻击两种情况,分析了导弹落点分布的特点,给出了导弹落点服从二维正态分布的推导过程和认为导弹落点纵向、侧向(或高度方向、侧向)独立分布的原因,并结合模型分析了随机因素对脱靶量的影响.推导了当导弹落点服从二维正态分布时圆概率和圆概率偏差的理论计算公式.
The characteristics of fall distribution of missile are analyzed under the circumstances of horizontal attack and vertical attack.The reasons are given,in which the fall points of missile are distributed as two dimensional normal distribution and the random variable X and Z(or X and Y)are independent.In addition,the influence of random factor on shoot error is analyzed based on math model and the formulae of circular probability and circular error probability(CEP)in theory are deducted.
