Abstract
Ground penetrating radar (GPR) devices use sensors to capture one-dimensional representations, or A-scans, of the soil and buried properties at each sampling point. Previous work uses reciprocal pointer chains (RPCs) to find one-dimensional layers in two-dimensional data (B-scans). We extend this work to find two-dimensional layers in three-dimensional data. We explore the application and differences of our technique when applied to vehicular mounted systems versus handheld systems and their distinct detection sequences. Not only can this work be used to display subsurface structure to a system operator, but we can also use changes in the subsurface structure of a local region to help identify buried objects within the data. We propose distinguishing buried objects from layers can reduce false alarm rates and may help increase probability of detection.
