An Improved Virtual Experiments based Linear Inversion for 2D Inverse Scattering

In this contribution the Virtual Experiments (VEs) paradigm as applied to inverse scattering problems, for 2D scalar field case, is addressed to show its actual possibilities and limitations. Recent analytical findings allow also to improve the imaging cabalities of a linear inverse approach based on VEs with comparable accuracy performance with respect to full non linear, and hence more computational burden demanding, microwave imaging strategies. A preliminary numerical test against simulated 2D geometry is given to support the proposed strategy.
