| 摘要: |
| 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。 |

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