摘　　要：基于电桥原理设计出了一套装备电缆故障检测装置:由信号发生器产生的射频信号输入进电缆,从故障点回来的反射波与入射波叠加形成驻波,然后对电缆的输入端的驻波电压值进行采样。接下来对采集到的实验数据进行分析,在分析过程中,采用了Bayes频谱估计方法。Based on the electrical bridge principle, a new set is designed to detect the fault of equipment cables. The signal from the RF generator is input into the cable, the wave from the discontinuity and the incident wave add at the input point, and a standing wave is generated. Then the voltage at the entrance of the cable is measured. In the process of analysis, the Bayesian Spectrum Estimation is used.
