Abstract

Ground penetrating radar (GPR) data has been used since the 1970's in geotechnical and engineering problems to image the soil and bedrock strata of the near surface. A comparison of the single fold method vs. the multifold method for acquisition and processing of GPR data is presented. Data are shown from an old lumber mill site on a river flood plain which has undergone excavation and backfilling. Results show an improved image can be attained by compensating for the problems related to complex geology, a complex wavefield and cultural noise. The results also show that in regions with a complex near-surface, multi-fold radar sections are the preferred method over single fold coverage. Steeply dipping horizons are placed in a correct spatial position and reflections are better imaged in the section by reducing coherent noise. -Authors
