摘　　要：推导了六端口技术估计波达方向的基本原理,分析总结了4种基于六端口技术的波达方向估计系统,它们与其它波达方向估计系统相比,具有精度高、频带宽、结构简单等优点,具有重要的应用价值。The basic principle of estimating diretion- of- arrival（DOA） with six-port technology is deduced, and four DOA estimation systems based on six-port technology are analysed and summarized. Compared with other DOA estimation systems, the systems based on six-port technology have such merits as high accuracy, wide bandwith and simple structure, which indicates that they have very important application values.
