Fault Location Method Research of Leaky Coaxial Cable Based on the Linear Frequency Modulation Pulse Compression

A new fault location method of leaky coaxial communication cable is proposed and demonstrated in the condition of experiment, which is based on linear frequency modulation pulse compression. The principle diagram of leaky cable fault location of linear frequency modulation pulse compression and its system composition are introduction. Experiment results are presented show that, in contrast to the single pulse reflection in which the coupling losses of single energy in the leaky cable transmission is larger, linear frequency modulation pulse compression can improve transmit signal energy and range resolution of fault point after pulse compression of its echo signal.
