Bayesian sequential test and Bayesian recursive estimation method can improve the traditional test evaluation method respectively from the aspect of hypothesis testing and parameter estimation.The two methods are used together here and applied to evaluation test of missile hit accuracy, which can combine test with estimation closely.It can make full use of priori information to make up for the lack of field data, and formulate a reasonable and effective evaluation scheme, which makes the test results more accurate and uses less ammunition for experiment.The example analysis shows that this method can effectively improve the test and estimation result, and is suitable for the evaluation test under the condition of small sample.
