针对现有高炮武器系统实装射击试验过程中存在的成本高昂、周期较长、试验组织繁琐等问题，提出了一种基于抽样的高炮武器系统虚拟射击试验方法，并针对样本量的确定这一核心问题进行了重点研究。首先从统计学的角度对动态精度飞行试验过程进行了科学分析，针对某一时刻的测量误差这一随机变量得到统计模型；其次从动态精度飞行试验的试验目的出发，得到动态精度统计方法；然后从统计模型出发提出了确定样本量的4个抽样指标；最后根据动态精度统计方法计算不同航次数量下的全航路动态精度指标，进而将不同航次数量下的动态精度指标结果应用于提出的抽样指标中，并进行仿真分析。仿真分析结果表明，确定的样本量与国军标规定范围相契合，体现出样本量确定方法的较高可信性。%Aiming at the deficiencies of high cost,long cycle and complicated organization process in anti-aircraft weapon system firing test,a virtual firing test method of anti-aircraft weapon system based sampling theory is proposed and as the core problem,the determination of sample sizeis mainly discussed in this paper. Firstly,the process of dynamic precision flying test is analyzed scientifically from the aspect of statistics and the statistical model is acquired by analyzing random variable of a certain moment’s measuring error. Secondly,the statistical method of dynamic precision is obtained according to the intension of dynamic precision flying test and then four sampling indexes for determining sample size is achieved according to statistical model. Finally,dynamic precision indexes of absolute flight path under different voyage sequence are calculated based on dynamic precision statistical method and then the results of dynamic precision indexes under different voyage sequence are applied into the proposed sampling indexes. Simulation analysis results show that the determined sample size is at the range of GJB which reflects the method’s high creditability.
