In this paper we deal with an indirect measure of the dielectric permittivity of the soil starting from GPRsurface data collected on a buried “cooperative” target, meant as an object buried on purpose and whoseextent is known a-priori. This target is exploited in order to achieve, from its image obtained from a suitableGPR data processing, an indirect measure of the dielectric permittivity of the embedding soil. GPR dataprocessing is based on a linear microwave tomographic approach funded on the Born Approximation. Usingthis Born approach on two-dimensional inversion tests, we investigate the effect of the soil's electricalconductivity and permittivity on this indirect measure and demonstrate that the electrical field scattered by aspot-like buried object permits an accurate estimation of the soil permittivity even when no information ofthe soil conductivity is available.

Abstract

In this paper we deal with an indirect measure of the dielectric permittivity of the soil starting from GPRsurface data collected on a buried “cooperative” target, meant as an object buried on purpose and whoseextent is known a-priori. This target is exploited in order to achieve, from its image obtained from a suitableGPR data processing, an indirect measure of the dielectric permittivity of the embedding soil. GPR dataprocessing is based on a linear microwave tomographic approach funded on the Born Approximation. Usingthis Born approach on two-dimensional inversion tests, we investigate the effect of the soil's electricalconductivity and permittivity on this indirect measure and demonstrate that the electrical field scattered by aspot-like buried object permits an accurate estimation of the soil permittivity even when no information ofthe soil conductivity is available.
