一种新的火炮武器系统射击精度试验方法

射击精度是反应火炮武器系统性能的最重要技术指标,通过对以往射击精度试验中采用的建立在大子样统计理论基础上的传统评定方法进行了分析,对目前采用的序贯截尾原理和方法进行阐述,并指出前两种方法没有利用验前信息,试验次数和试验风险比较大等缺点,由此提出一种新的贝叶斯截尾序贯检验法。这种小样本统计推断方法的基本思想是充分利用已有的验前信息,实现了多阶段试验信息的综合利用,能够减少试验次数,缩短试验周期,节约试验经费。

A New Method for Artillery Weapon System Shooting Accuracy Test

Shooting accuracy is the most important index reflecting the quality of artillery weapon system. In this paper, we analyzes the traditional evaluation for artillery weapon system in the test of shooting accuracy which is built upon large sample statistic theory, discusses the principle and method of sequential analysis. Point out a defect that these two methods have not used the information before test, the number of times and risks are bigger. Bring up a new method of Bayes truncation Sequence, the essential thought of this little sample statistical inference is fully utilizing the information before test, realizes many phases test information comprehensive utilization. It can reduce the number of test times, shorten test cycle and save the test funds.
