Abstract
A method for detecting a buried non-conductive pipe includes transmitting, by a radio frequency (RF) transmitter, guided RF energy through one end of the non-conductive pipe, receiving, by a RF receiver, electromagnetic signals due to RF energy leaks in one or more locations along the non-conductive pipe, and processing, by one or more processors, the received signals to determine a location of the non-conductive pipe. A system for detecting a buried non-conductive pipe includes a RF transmitter configured to transmit guided RF energy through one end of the non-conductive pipe, a RF receiver configured to receive electromagnetic signals due to RF energy leaks in one or more locations along the non-conductive pipe, and one or more processors configured to process the received signals to determine a location of the non-conductive pipe.
