摘要 针对快速准确定位电缆故障点的问题,文中采用极化敏感阵列分析电缆故障检测的数学模型,实现对故障点方位角和距离的精确估计。采用增加COLD天线改进DOA估计算法进行近场故障源估计。通过计算机仿真,从理论上验证了该算法的有效性。 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 twoodimension vector antenna. Computer simulation shows that this algorithm is available theoretically.
