An Algorithm for Buried Pipeline Detection Using a 3-D Bistatic Imaging Radar

摘要

Pipeline detection is a problem with important applications in oil and gas pipeline transport systems maintenance. The scattering mechanism for extended targets such as pipelines is different than the scattering mechanism of localized targets which poses a challenge when trying to detect and image such targets using traditional imaging schemes such as back-projection algorithm. In this paper, a novel method for detection and estimation of pipeline depth, orientation and displacement is proposed. The method utilizes the unique way a pipeline scatters incident waves to find the actual bistatic path the signal takes and compensate for such path to focus the signals gathered by a moving receiver from the pipeline. The method is explained and preliminary results are presented as a proof of concept.
