摘　　要：简述了天线群时延的基本概念。系统阐述了利用矢量网络分析仪测量导航天线时延的三种方法,即标准探头法、两相同天线法和三天线法。推导出利用矢量网络分析仪测量天线时延的原理方程,并简述了时延测量的方法程序。In this paper, basic concept of antenna group delay is described simply. Three meth- ods for measuring navigation antenna time delay are considered systematically using vector network analyzer, and they are standard probe method, two identical antenna method and three antenna method. Princ vector network analyzer, an iple equations of measuring antenna time delay are derived using d test procedures for antenna time delay are described simply.
