“…Among different techniques well-suited to numerically solve the configuration depicted in the first section, one can cite Finite Difference Time Domain techniques ( [16], [17]) well adapted for the scattering by short pulses in time domain. In the frequency regime, the cylindrical wave expansion is very efficient in the framework of cylinders buried under a plane or moderately rough interface problem [18], [19].…”

International audienceWe propose an approach for probing the nearsubsurface based on the use of a single frequency combined with a multistatic configuration. Our goal is to retrieve the near-subsurface permittivity spatial distribution from measured electromagnetic fields. To that end, efforts have been done on the calibration procedure. In particular, the radiation pattern of the antenna is taken into account in the modeling of the scattering problem. We also preprocess the measured fields with an efficient method which takes profit of the spectral bandwidth properties of the scattered field allowing the removal of the residual interface contribution. Imaging results of shallowly buried target embedded in a high-losse medium are presented to assess the well-behavior of the proposed methodology
