摘　　要：阐述了微波组件一致性指标在无基准情况下的配组需求。介绍了基准归一法、均值排序法、欧氏距离法等常规手段分组配对的优缺点。提出一种在相关性系数分析方法基础上的新配组方法,并用软件实现了该方法。实测证明,相对于人工配组和其他常规配组方法,该方法提升了配组效率和准确率。此外,此方法能够较好识别数据分布的整体趋势,在满足一致性指标前提下优先匹配趋势最接近的数据,可使整机性能最优。The matching requirements of microwave module’s consistency without reference module are described.The conventional methods such as benchmark ranking,mean ranking,Euclidean-distance are introduced.A new group matching method based on the analysis of correlation coeffi cient is proposed and implemented by software.Compared with manual and other conventional methods,this method improves grouping effi ciency and accuracy.In addition,this method can better identify the overall trend of all the data traces,and give priority to grouping the traces with the closest trend for each other on the premise of meeting the consistency requirements.It can optimize the performance of the whole system to the best.
