Abstract
Ground-penetrating radar: a modern three-dimensional prospection method
J Leckebusch
213 - 240
The article gives an overview of the various aspects of ground-penetrating radar as used in archaeology. After a short overview of the historical development of the technique, the most important physical parameters and principles are explained. This includes relative dielectric constant, conductivity, attenuation, horizontal and vertical resolution, wavelength and footprint. The focus is on data processing and some of the pitfalls involved. Several algorithms from seismic data processing are described, including migration. Stress is laid on the generation of time- or depth-slices as the basis for displaying the data. Using three-dimensional visualization techniques can enhance this, but interpretation in combination with other data, preferably within a geographical information system, remains the important last step. The advantages of modelling are explained and presented with the range of possible applications. Many the techniques and methods described are subsequently used in four case histories, ranging from a survey on a lake to a three-dimensional model of a part of a Roman town. Finally some thoughts about the future development of the method are presented.
Geophysical surveys of Bury Walls hill fort, Shropshire

The hill fort of Bury Walls in Shropshire has been surveyed extensively by topographical and geophysical methods with the aims of recovering evidence for occupation, characterising the use of the hill fort and clarifying the chronological development of the site. Topographic surveys delineated the current extent of the fort and its massive fortifications. Resistance surveys showed several interesting features inside the fort, including extensive use of the geology to make flattened ledges in an otherwise quite uneven fort interior, a possible cross dyke, interior roads and traces of possible dwellings. Magnetic gradient surveys again showed clearly the possible cross dyke. Additional geophysical surveys attempted to define the depths of these features found in the resistance and magnetic gradient maps.
Comparison of geophysical techniques for investigating an infilled ditch at Bury Walls hill fort, Shropshire

Five geophysical survey techniques were used to investigate the infilled section of the outer ditch at the Iron Age hill fort of Bury Walls, Shropshire. The techniques were resistance mapping and four profiling methods: resistivity sounding, ground-penetrating radar (GPR), P-wave seismic refraction and S-wave seismic refraction. The ditch was clearly visible on the resistance map and on GPR profiles, but no depth estimate was obtainable from these surveys. The most successful survey technique was S-wave seismic refraction, both for determining whether the ditch was present on a profile and for obtaining an estimate of its depth. A key factor for the success of S-wave seismic refraction profiling was that the ditch had been excavated into the sandstone bedrock.
