Multi-Offset GPR Profiling at the Aquifer Test Site Tettnang (SW Germany)

P024 MULTI-OFFSET GPR PROFILING AT THE AQUIFER TEST SITE TETTNANG (SW GERMANY) Abstract 1 Multi-offset ground-penetrating radar (GPR) data were collected in a glacial delta environment with 20-30° dipping gravel beds (aquifer test site Tettnang Southwest Germany). We apply pre-stack processing techniques and normal moveout velocity analysis in preparation of stacking. Stacked GPR sections show significant improvements in depth of investigation and reflector imaging over a standard constant-offset section. This allows a more reliable interpretation of geological structures. The resolution of shallow reflectors in the stacked section is improved by muting of wide-angle reflected energy.
