Microwave imaging (MWI) techniques represent an assessed tool to face a lot of diagnostic problems in which a non-invasive analysis of an unaccessible area is required, since they allow to obtain qualitative and quantitative information about the nature of the targets embedded inside an imaging domain. In this communication, the authors propose an application of MWI techniques to a well-known aspect-limited configuration, that is the one proposed in Ground Penetrating Radar for demining application. More in details, we applied the theory of Compressive Sampling (CS) in order to improve the quality of recoveries and, in the meanwhile, reduce the number of data acquired and employed in a 3-D fashion in the case of low-moderate dielectric objects, and therefore the well-known Born Approximation has been exploited in the inversion algorithm.
