TI  - Bayesian Compressive Sensing in Multi-Resolution Contrast Source Estimation
N2  - This work proposes a sophisticated multi-step inverse scattering strategy within the contrast source inversion (CSI) framework to reconstruct non-Born scatterers. It adopts a multi-resolution (MR) scheme to represent contrast sources, which are iteratively estimated using a Bayesian compressive sensing (BCS) algorithm that encourages sparse solutions. The method's accuracy and stability are confirmed through extensive testing. Benchmark comparisons demonstrate the approach?s strong performance relative to contemporary advanced techniques.
