摘要:

针对传统方法在特小子样下对高性能弹药命中概率的计算存在精度不高的问题,提出了一种基于贝叶斯假设检验的改进算法。在弹药分布落点为圆散布假设的前提下,通过分析弹药脱靶量的边缘分布列出命中概率的计算公式,并采取贝叶斯假设检验的方法,在充分利用先验信息的同时,采用间接、直接两种算法计算出假设检验参数的累积分布函数,在满足指定检验水平所要求的置信区间的前提下,估计出弹药落点密集度。仿真结果表明,所提算法与传统方法相比极大地简化了计算步骤、提升了计算结果的准确性,为计算特小子样下的弹药命中概率提供了参考依据。

Abstract:

Addressing the issue of low accuracy in calculating the hit probability of high-performance ammunition in ultra-small subsample using traditional methods, an improved algorithm based on Bayesian hypothesis testing is proposed. Under the assumption that the distribution of ammunition impact points follows a circular dispersion, the calculation formula for the hit probability is derived by analyzing the marginal distribution of the ammunition miss distance. By utilizing Bayesian hypothesis testing, the cumulative distribution function of the hypothesis testing parameters is calculated using both indirect and direct algorithms while fully utilizing prior information. The ammunition impact point density is estimated under the premise of satisfying the confidence interval required by the specified testing level. Simulation results show that the proposed algorithm significantly simplifies the calculation steps and improves the accuracy of the calculation results compared to traditional methods, providing a reference for calculating the hit probability of ammunition under ultra-small subsample.
