Abstract:

In order to locate the cable fault quickly and accurately,this article uses the polarization sensitive array analyzing mathematic model for cable fault detection to acquire the precise estimation of fault location's angle and distance.The improved DOA estimation algorithm can estimate near field by adding a COLD two-dimension vector antenna.Computer simulation shows that this algorithm is available theoretically.

Key words: cable fault accurate location;polarization sensitive array;direction of arrival;near field
