基于Bayes方法的航空子母炸弹制导精度分析

Guidance Precision Analysis for Aerial Dispenser and Bomblet Based on Bayesian Method

针对风修正系列航空子母炸弹的制导精度鉴定问题,根据炸弹的试验投放情况和毁伤机理,讨论了毁伤效能战术指标与制导精度指标之间的关系。在小子样条件下,运用Bayes理论方法,提出了航空子母炸弹的制导精度和布撒均匀度鉴定方案,研究了对Bayes SPRT序贯方法的改进。仿真结果表明:所提出的方案可以减少所需的试验样本量,可以用于小子样条件下航空子母炸弹的精度鉴定问题。

Taking aim at the appraisal problem of guidance precision for wind correction aerial dispenser and bomblet, the relationship of indexes between the destruetive effieieney and guidanee preeision was discussed, according to release case and destructive mechanism of the dispenser and bomblet. The appraisal scheme of the guidance precision and the dispensing uniformity for the dispenser and bomblet was proposed and the sequential probability ratio test was improved by Bayes theory under the condition of small samples. The simulated results show that the scheme can reduce the needed sample amount and be used for appraising the precisions of the dispenser and bomblet.
