Gpr Prospecting and Inverse Scattering With Shifting Zoom in the Archaeological Site Of Cavallino, Lecce, Italy

In this paper we show the results of a GPR measurement campaign performed in the archaeological site of Cavallino, in eastern-southern Italy, that hosts an ancient Messapic settlement (8th-2nd century B.C.). Beyond a classical elaboration of the data, wherein the focusing is achieved by means of a migration algorithm, also an unconventional processing has been performed, based on a linear inverse scattering algorithm regularised by means of the SVD of the relevant operator. Due to the electrically large investigation domain, in order to apply the inverse scattering algorithm, a shifting zoom procedure has been adopted as described in the following.
