N2  - This work presents a numerical validation of an innovative inverse scattering (IS) technique for the microwave imaging of buried objects through the deterministic inversion of wideband ground penetrating radar (GPR) data. The developed methodology is based on an iterative multi-focusing strategy and on a multi-frequency (MF) formulation of the IS equations. The minimization of the arising MF cost function is performed by a customized conjugate gradient (CG)-based solver. Some numerical results are presented in order to validate the effectiveness of the developed methodology under different operating conditions, by considering a variation of the shape/material of the unknown objects, as well as a variation of the level of noise on the measured time-domain total field. Moreover, a comparison with respect to a state-of-the-art approach based on a Frequency Hopping (FH) strategy is given, as well.
