We have developed a fully three-dimensional electromagnetic inverse scattering technique in a multilayered medium via the contrast source inversion. The key issues on the three-dimensional (3-D) forward and adjoint operations related to the dyadic Green's operators are briefly addressed to ensure the efficient performance of the algorithm in layered media. It is shown that it is feasible to achieve good reconstruction quality with only a few sources and a two-dimensional receiver array, provided that the signal-to-noise ratio is adequate. The effects of the interface and of the uncertainty in the background layered medium are illustrated in the simulation. The developed 3-D electromagnetic inverse scattering technique can be effectively applied to surface ground penetrating radar survey in multilayered media.
