霰弹弹着点分布均匀性评价方法研究

针对霰弹定型试验中提出的弹着点分布均匀性战术技术指标评价方法问题,将弹着点的二维圆内均匀性分布分解为一维径向均匀性分布和周向均匀性分布分别评价。应用MATLAB实现了一维均匀分布相容检验临界值的计算方法,该方法计算得到的不同的置信水平下各样本容量的相容性检验临界值。对一维均匀分布相容检验临界值的样本容量进行了扩展,以满足某些霰弹的弹丸数较多的实际要求。

RESEARCH ON EVALUATION METHODSOF GRAPESHOTIMPACT POINTS DISTRIBUTION UNIFORMITY

To evaluation methodological question of tactical and technical quality index raised in grapeshot type testing for impact points uniformity, two-dimensional uniformity distribution within one circle is divided into one-dimensional radial uniformity distribution and one-dimensional circumferential uniformity distribution to evaluate respectively. MATLAB is applied to achieve a method of compatibility test critical values calculation of one-dimensional uniformity distribution and compatibility test critical values of each sample size are calculated under different confidence level with the method. Sample size of compatibility test critical values has been extended to meet practical requirements that pellets quantities of some types grapeshot are large .
