| 摘 要： | 基于弹道导弹试验较少的实情,采用数据分组、再微重复组合数据组求方差的方法求出大量的方差样本,作出了较准确的方差直方图.根据直方图的极大点求出了弹道导弹落点方差的先验分布密度,提高了所得先验分布的可信性,为采用Bayes方法分析弹道导弹的落点精度提供了可靠的基础.

| Abstract: | This paper gives out a method to gain large samples of variance and to solve prior distribution density of variance of ballistic missile fall point by grouping the simulation test data as large samples, and tiny-repeating assembling the data-group, considering real test is very little. This method improves the creditability of prior distribution solved, provides reliable base for analysis precision of ballistic missile fall point also. This method can be used diffusely in the evaluation of ballistic missile test. |
