Buried Object Discrimination in a Ground Penetrating Radar Radargram

ISSN 2277 – 503X | © 2013 Bonfring Abstract--Ground Penetrating Radar (GPR) is a nondestructive technique used for the location of objects or interfaces buried beneath the earth’s surface or located within a visually opaque structure. This research work proposes techniques for buried object discrimination for the images generated by GPR by using GPR frequency-domain spectral features. The motivation for this approach comes from the fact that landmine targets and clutter objects often have different shapes and/or composition, yielding different Energy Density Spectrum (EDS) that may be exploited for their discrimination. The proposed system comprises cascade of two stages: Pre Processing Stage, followed by Discrimination Stage. Pre – Processing eliminates the ground bounce and clutter to get an enhanced image. Enhancement is followed by Landmine or clutter Discrimination using Energy Density Spectrum. All implementations are done using MATLAB.
