Processing microwave experimental data with the distorted born iterative method of nonlinear inverse scattering

Diffraction tomographic method for the imaging of dielectric bodies is very popular due to its simplicity and speed. However, such a theory makes the assumption that the scattered field is linearly related to the dielectric profile of the object. In order to account for the multiple scattering effects, a nonlinear theory has to be developed where the scattered field is nonlinearly related to the object function to be reconstructed. A number of fast forward scattering algorithms have been developed to achieve this purpose.link_to_subscribed_fulltex
