Microwave tomography for processing of GPR data at Ballachulish

Abstract

In this paper we present the results of a microwave tomography algorithm applied to the GPR data gathered at the archaeological site of North Ballachulish (Scotland). The GPR survey had the aim of mapping the contours of the peat basin and investigating the possibility of archaeological remains. A linear inverse scattering algorithm has been applied on the data, and the results are compared with those achieved by means of the Reflex code. The results of this work show the possibility of applying the linear inverse scattering approach to a massive amount of data for large-scale investigations, and also of showing the possibilities offered in some cases by pre-processing the data (interpolation procedure) so as to improve the result of the overall diagnostics procedure.
