Data Processing and Image Enhancement of GPR Surveys of Roman Villas in Austria

Introduction The quality of ground penetrating radar data can suffer from many different sources of noise. Some of these sources are varying distances of the antennas to the ground due to rough surfaces, different surface conditions (e.g. compression due to tractor tracks), external electromagnetic fields and instrumental noise and instabilities (Seren, 2007). Analyses of recorded raw data and knowledge of the source of noise lead to specialised processing methods to improve the signal-to-noi..
