Microwave tomography for processing of GPR data at Ballachulish

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.

Ground penetrating radar investigations at North Ballachulish Moss, Highland, Scotland

Ground-penetrating radar was used to map the underlying topography of North Ballachulish Moss. Ground-truthing, in the form of sediment coring and test-pitting, provided corroborative evidence for the peat depths as defined by the radar survey. Trial trenching revealed that a suite of radar anomalies identified during the course of the survey related to a buried prehistoric surface with an associated abundance of wooden stakes and twigs.

The shrine of edward the confessor: A study in multi-frequency gpr investigation

Following an earlier investigation into the 13th Century Cosmati mosaic in Westminster Abbey, Ground Penetrating Radar (GPR) investigations were commissioned in order to locate the site of a large royal tomb. Antennas of 400MHz and 4GHz frequency were used in the area of the High Altar steps and on the floor of the current Shrine Chapel. The investigation uncovered evidence of the target tomb, a number of other graves, some previously unknown, and at least one buried object. The paper briefly discusses the frequencies selected and illustrates how these have resulted in better understanding of the archaeological and historical evidence.

Barcombe Roman Villa: An exercise in GPR time slicing and comparative geophysics

Barcombe Roman Villa, a site under threat of destruction from ploughing, has been investigated by use of resistivity, field walking and excavation. GPR survey was added to these techniques and a comparison is made between the composite picture provided by the former and time slices derived from the latter.

Imaging of Scarce Archaeological Remains Using Microwave Tomographic Depictions of Ground Penetrating Radar Data

The Romano-British site of Barcombe in East Sussex, England, has suffered heavy postdepositional attrition through reuse of the building materials for the effects of ploughing. A detailed GPR survey of the site was carried out in 2001, with results, achieved by usual radar data processing, published in 2002. The current paper reexamines the GPR data using microwave tomography approach, based on a linear inverse scattering model, and a 3D visualization that permits to improve the definition of the villa plan and reexamine the possibility of detecting earlier prehistoric remains.

GPR as an imaging device: Some problems & potential solutions

Ground Penetrating Radar (GPR) is an invaluable tool in a wide range of applications. In each sphere of activity to which the technology is applied, however, there is a tension between gaining meaningful information and the time and resources committed to data collection, processing and interpretation. In the light of the current world economic crisis, this is not likely to ease.
