序贯验后加权检验法在激光告警试验中的应用

Sequential posterior odd test approach in laser warning system test

为了减少试验样本数、降低试验消耗和缩短试验周期,采用序贯验后加权检验法,利用试验数据的验前信息进行序贯决策,以减小试验所需样本数。以激光告警试验为例,将序贯验后加权检验法与经典的数据处理方法进行对比。结果表明,采用序贯验后加权检验法可以减少所需的试验样本数,而且试验指标取值以及犯两类错误概率取值对试验样本数有较大影响。

Sequential posterior odd test approach can be used to reduce the size of the test samples and test cost,shorten the test period owing to its adoption of the test data information before test. Taking laser warning test for example, comparing with the traditional test data processing method, the sequential posterior odd test approach needs smaller samples, not only the test target value but also the probability of two kind errors have great influence on test sample size.
