Abstract :
An efficient inverse scattering algorithm is developed to reconstruct the permittivity profile of two-dimensional(2-D) dielectric objects buried in planar multilayer environment. The forward model of this inversion scheme is based upon first order Born approximation and 2-D planar multilayer scalar Green function. A planar multilayer diffraction tomography algorithm is established subsequently. Numerical results are provided to illustrate the performance of the inversion scheme.
