介绍了一种基于FDR(频域反射)测试技术的馈线驻波故障定位方法及装置设计。通过发送特定频带的扫频测试信号，将发送功率值、故障馈线反射信号与入射信号矢量叠加的功率信号值通过通信接口传送到上位机，上位机软件根据这两个功率值计算馈线故障点距离，实现对馈线故障的精准定位。

This paper introduces a Frequency Domain Reflectometry (FDR)based method and apparatus design for feed cable Voltage Standing Wave Ratio (VSWR) fault location. By sending frequency sweeping test signals at specific bands, it transfers the power signal value overlaid by the sending power value, the faulty feed cable reflected signal and the incident signal vector through the communication interface to the computer and its software calculates the distance of the feed cable fault points on the basis of these two power values, thus achieving the accurate location of the feed cable fault.
