Extension of the GMMV-Based Linear Method to Quantitative Inverse Scattering

The linear shape reconstruction method based on the generalized multiple measurement vectors model is a newly proposed approach that is able to effectively retrieve the morphological information of dielectric/metallic scatterers with competitive imaging resolution. In this letter, we have extended this approach to quantitative inversion, with which a coarse estimation of the dielectric parameters can be obtained in an efficient way. The inversion of the transverse magnetic polarized Fresnel datasets from the year 2005 demonstrates applicability of the proposed method to real-life applications.
