Abstract

This report introduces an advanced multi-step inverse scattering method within the contrast source inversion (CSI) framework to reconstruct non-Born scatterers. The approach employs a multi-resolution (MR) representation to flexibly model the unknown contrast sources, which are iteratively estimated using a Bayesian compressive sensing (BCS) technique. The proposed MR-BCS-CSI method is rigorously evaluated through different case studies, demonstrating high accuracy, stability, and robustness. A comparative analyses is performed to further highlight its effectivenes.
