Article Title：Cave detection in limestone using ground penetrating radar
Abstract：
Ground penetrating radar (GPR) is becoming a more common component of the standard array of geophysical techniques that are used by archaeologists. In this paper, we report on the use of GPR to survey an area of archaeologically important karst topography at Kitley Caves in Devon, U.K. We describe the use of GPR to detect voids within a limestone outcrop, as an aid to locating cave systems which might contain sediments suitable for excavation. The performance of the GPR equipment is analysed and the results compared to those obtained with an electrical resistance survey carried out at the same location. In particular, the depth of penetration of the GPR is estimated, and we report discernible echo signals from a much greater depth than is usually reported in archaeological applications of GPR.
