Application of the multiplicative regularized contrast source inversion method on 3D experimental Fresnel data

This paper presents the results of inversion of multi-frequency electromagnetic scattered field data, measured by the Institute of Fresnel, Marseille, France, from three-dimensional (3D) homogeneous objects, both for co-polarization and cross-polarization antenna orientations. The reconstructions were obtained by using the multiplicative regularized contrast source inversion (MR-CSI) method. The inversion results indicated that the MR-CSI is able to robustly and efficiently invert these 3D data sets using minimal a priori information.
