Morphological processing of electromagnetic scattering data for enhancing the reconstruction accuracy of the iterative multi-scaling approach

This work presents a methodology to locate and characterize multiple unknown scatterers exploiting the scattered electromagnetic radiation collected oft a measurement region outside the area under investigation. In many practical cases, an accurate quantitative imaging of the scenario under test is required and it can be reached by using a high resolution representation of the dielectric profile of the scatterers. Towards this aim, an enhanced iterative multi-resolution procedure that exploits a morphological processing for detecting and focusing oft different non-connected regions-of-interest has been developed A suitable set of representative numerical results will demonstrate that the proposed approach is able to efficiently detect the objects in the imaging scenario and to enhance the accuracy in reconstructing multiple scatterers.
