GPR prospecting on circular surfaces: preliminary results

In this paper we deal with a data processing algorithm applied to data gathered along a circular surface based on a scalar 2D linear inverse scattering approach. This problem is of interest with regard to prospecting of historical or modern columns, in particular with the aim to detect internal fractures or metallic hinges. The GPR prospecting on a circular surface presents both theoretical and practical extra-difficulties if compared to the homologous operation performed on a planar surface.
