Subsurface imaging 3-D objects buried in layered medium with electromagnetic waves has recently attracted significant interests. Due to the uncertainty of dielectric parame- ters of layered background media in practice, most of existing electromagnetic inverse methods reconstruct the buried objects unfaithfully. In order to accurately reconstruct the objects buried in multilayered media with unknown dielectric parameters, we develop a new imaging method named electromagnetic inverse scattering series method (EISSM) for imaging 3-D objects in mul- tilayered media. The 3-D EISSM combines the inverse scattering series (ISS) theory with a multi-array tomographic approach. It directly reconstructs the positions of the buried objects (not their dielectric properties) solely with the dielectric parameters of free space according to the discontinuities of dielectric parameters. Moreover, the effects of multilayered media to the position error predicted by EISSM are also analyzed and discussed. Aiming to validate the fea- sibility of the developed 3-D EISSM, some numerical simulations are given as well as the results reconstructed by commonly used time reversal mirror (TRM) technique. Through the simula- tions, the EISSM is capable of positioning 3-D targets buried in multilayered media with less error than traditional TRM.
