基于贝叶斯原理的小子样试验导航误差评定方法

针对鉴定试验花费大、周期长的问题,提出一种水下无人航行器导航误差小子样贝叶斯试验CEP评定方法。该方法综合运用大量验前子样,对其进行相容性检验,以确定有效的验前子样,并运用统计推断理论获取验前信息。根据在验收试验中获取的验后子样获取验后信息,利用贝叶斯理论推出无人航行器满足CEP指标的概率。实例结果表明了方法的有效性和实用性。

Small Sample Navigation Error Assessment Experiment Based on Bayes Principle

Aiming at the problems of high expenses and long period on navigation error assessment experiments of UUV under the condition of small samples,a method of small sample Bayes experiment was presented to assess the CEP of UUV.The method carried out the consistency test through large prior samples to acquire valid prior sample,then obtained the prior information through statistical inference.The presented method adopted Bayes theory to infer the CEP with the post information of informal experiments.Experiment ...
