New strategy to locate buried objects in highly lossy ground

An electromagnetic scale model, with well defined and variable electrical parameters, has been constructed, to investigate experimentally the optimum ground-probing radar strategies for use in extremely lossy conditions. A new geometry is proposed that reduces the dynamic-range requirements of a ground-probing radar, allows the permittivity of the medium to be estimated, and provides a clear time window for close targets to be detected. An image-retrieval algorithm is described for image reconstruction.
