Abstract :
In this work, we focus on the 3D image reconstruction of buried objects in layered media with sources and receivers located in the top layer. The inversion of scattering data collected by such a partial aperture is in principle more difficult than in the case of a full aperture because the non-uniqueness become more severe. Both the Born iterative method (BIM), and the distorted Born iterative method (DBIM) are used as the inversion methods. In this work, the stabilized biconjugate-gradient fast Fourier transform (BCGS-FFT) method is applied for calculating 3D electromagnetic scattering in general planarly layered media.
