A Robustness Analysis of the Iterative Multi-Scaling Approach Integrated with Morphological Operations.

The accuracy and the robustness of the iterative multi-resolution strategy in dealing with inverse scattering problems involving multiple objects configurations has been enhanced by introducing a suitable morphological processing. In an iterative fashion, a set of scatterers are reconstructed by progressively increasing the resolution level in the Regions-of-Interest (RoIs), where the objects are localized, identified through suitable morphological operations. Selected numerical results are presented and discussed in order to assess the accuracy and effectiveness of the morphological-based processing. [ABSTRACT FROM AUTHOR]
