摘要
讨论了再入飞行器落点密集度评定的序贯截尾方法,给出了预测m步的序贯方案,并把这种方案和SPRT进行了比较,求出了Bayes验后风险以及两类错误的概率,最后考虑了截尾情况下的评定方案。
The Sequential Truncated Method of dispersion detecting algorithm of the reentry vehicle impact points is studied. The m-step look ahead procedure is given. This procedure is compared with the sequential probability ratio test (SPRT),and the Bayes posterior risk and the probabilities of Type Ⅰ and Type Ⅱ error of the Bayes sequential procedure are calculated. Finally,the truncated procedure is considered.
