Multi-Resolution Multi-Physics Imaging of Free-Space Targets

The joint inversion of electromagnetic (EM) and acoustic (AC) scattered data is addressed for the multi-physics (MP) imaging of unknown targets in free-space. The regularization properties yielded by a data-fusion approach are enhanced by integrating it with a multi-resolution (MR) strategy aimed at adaptively increasing the pixel density and exploiting progressively-acquired information on the imaged domain. An illustrative example is shown to preliminarily verify the effectiveness of the proposed MR-MP method
