子弹药抛撒散布均匀性评价是子母弹研究及工程应用中的一项重要内容.现有评价方法主要基于χ2检验法,存在着检验结果对分组区间的划分敏感以及要求样本数量足够大等缺点.前者使评价结果的可信度降低,后者使其应用范围受到限制.本文在核估计的基础上,提出一种改进的χ2检验法--核估计χ2检验法.利用该方法对某导弹子母战斗部的子弹药抛撒散布均匀性进行评价,并与现有评价方法作对比.结果表明,该方法能克服现有评价方法的不足,且能精细地反映子弹药散布情况.

It is one of important subjects to estimate uniformity of submunition dispersion points of fall. The current method using χ2 test has two disadvantages, which are that estimated results are sensitive to sub area partition, and large sample capacity is required to obtain correct results. The former makes confidence of estimated results decrease, and the latter makes applied scope of the method restricted. A modified χ2 test method called kernel χ2 test based on kernel density estimation and χ2 test was presented to improve these disadvantages. Submunition dispersion uniformity of a certain cluster warhead was estimated by the modified method and compared with the current method. The estimated results show that the modified method can overcome disadvantages of the current method, and describe submunition dispersion exactly.
