天线结构谐振频率及其测试方法的探讨

RESEARCH ON THE RESONANT FREQUENCY AND ITS MEASUREMENTS OF THE ANTENNA STRUCTURE

结构谐振频率是射电望远镜机械结构系统的几个重要参数之一。本文讨论了影响天线结构谐振频率的几个主要因素及谐振频率的实测方法。并实测了国内第一台φ25米射电望远镜的结构谐振频率。

The resonant frequency is one of the most important parameters in the mechanical structure of radio telescope. This paper discusses the factors which affect the resonant frequency directly, and technique of measurement. Applied to the first φ 25 meter radio telescope in China.
