Abstract
A method for locating underground pipes from a pulse radar image is present ed. The method employs the Laplacian of Gaussian filter to extract edges an d employs the Hough transform to determine the depth of the pipes. A prelim inary experiment showed its ability to detect deeply buried pipes with weak signal echoes.
