Dealing with Aspect-Limited Data Through an Innovative Microwave Imaging Multi-Source Technique: Potentialities and Limitations

In this contribution, an innovative methodology aimed at increasing the amount of scattering data (avoiding further a-priori assumptions on the investigation domain) is analyzed. According to the multi-source (MS) approach, the investigation domain is illuminated by means of different probing sources, each of them characterized by a proper (and different) radiation pattern, to induce different scattering interactions able to show" different "aspects" of the scatterer under test. Integrated with a multi-view strategy and recurring to the iterative multi-scaling procedure [Donelli et al., 2006]
