| 摘要: |
| 对带有均匀抛撒子弹头的常规导弹的命中精度评定, 其关键在于子弹散布中心分布参数的准确估计。通常的方法由每次试验的子弹落点数据获得一个子弹散布中心, 再由少数的几个散布中心数据、运用经典的统计方法求散布中心的正态总体分布参数, 其不足之处在于小样本条件下采伪的概率很高。考虑到子弹散布中心只是子弹落点数据的一阶矩, 并不能充分表达子弹落点数据所蕴含的信息量, 而子弹落点个数远远大于导弹试验的次数, 子弹落点所蕴含的信息比子弹散布中心所蕴含的信息要丰富得多。鉴于此, 研究了一种子弹散布中心总体分布参数融合估计的新方法。 |

| Abstract: |
| On evaluating the hitting precision of a missile which throws sub-missiles, it is a key question to estimate the normal distribution parameter of the sub-missile dispersion center. The usual method is, to find a sub-missile disper firstsion center first from each group data of the sub-missile's falling point coordinate, then to estimate the parameters according to a few data of dispersion center using the classical statistic method. Its shortcomings are the high probability to make a wrong conclusion. Considering that the sub-missile dispersion center, which cannot sufficiently express the information contained in the sub-missile falling point data group, is only its first moment, in this paper a new method on fusion estimating the distribution parameter is researched. |
