Two georadar lines are presented in a comparison of conventional georadar processing flows and flows based on a Gabor deconvolution algorithm. The imaging goal is to map nearsurface sediments above a Quaternary fault in the Piano di Castelluccio Basin in central Italy. There is a history of earthquake risk in this region and the georadar data were acquired for infrastructure planning as part of the Italian Probabilistic Seismic Hazard Assessment (PSHA). There is hope that georadar data can be used to eventually tie reflection seismological fault images to the surface. We find that the processing flow that is based on Gabor deconvolution is significantly better than the conventional flow and this is likely due to Q compensation characteristics that are intrinsic to Gabor deconvolution.

Abstract
Two georadar lines are presented in a comparison of conventional georadar processing flows and flows based on a Gabor deconvolution algorithm. The imaging goal is to map nearsurface sediments above a Quaternary fault in the Piano di Castelluccio Basin in central Italy. There is a history of earthquake risk in this region and the georadar data were acquired for infrastructure planning as part of the Italian Probabilistic Seismic Hazard Assessment (PSHA). There is hope that georadar data can be used to eventually tie reflection seismological fault images to the surface. We find that the processing flow that is based on Gabor deconvolution is significantly better than the conventional flow and this is likely due to Q compensation characteristics that are intrinsic to Gabor deconvolution.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
