天馈系统性能参数的细微特征分析

本文给出了一种简便的天馈系统性能参数的细微特征分析方法。应用该方法，可以
对天馈系统的反射系数、驻波比、故障距离和回波损耗等参数进行细微分析，在天馈系统出现重大故障前发现细小的、难于确认的问题，打破了传统的在发生故障之后修理的维护方法。

Minute features analysis of performance parmeter of the antenna and cable systems HU Lin ZHANG Jing-tang (Information Engineering University, Zhengzhou Henan 450002, China) Abstract In this paper, a simple and convenient method for minute features analysissing of performance parameter of the antenna and cable system is presented. With this method, we can analysis some parameters of the antenna and cable system, such as reflectance, standing wave ratio, DTF(distance-to-fault) and return loss, it breaks away from the traditional fix-after-failure maintenance process by  finding small, hard to identify problem before major failures occur.
Key words antenna and cable system, performance parameter, distance-to-fault
