再入飞行器落点准确度的统计分析

本文研究再入飞行器的落点准确度(系统性偏差)的检验和估计方法。首先,文中引入了准确度的容许限的概念,在此基础上给出了Bayes验后加权概率比检验方法。关于落点系统偏差的估计,讨论了Bayes估计方法及带有约束的Bayes估计方法。文中注意了充分运用试验前的信息,以便使落点系统偏差的评估能在小子样场合下进行。

Statistical Analysis of Accuracy of the Fall Point for Reentry Vihicle

In this paper, the detection and estimation of the fall point for reentry vehicle isstudied. In the first, we introduce the concept of addmissible accuracy limit and then givethe Bayesian posteori probability ratio odd testing method. For the systematic error offall point, the Bayesian and constraint Bayesian estimation are discussed. The attentionfor using prior information is sufficiently mentioned so that the decision making of fallpoint can be carried out under the condition of small sample number.
