In such a framework, multi-resolution techniques have recently appeared in order to increase the effectiveness of the inversion procedure. To properly deal with the ill-posedness characterizing their mathematical model and at the same time enhance the achievable spatial resolution, such a paper presents and discusses several multi-resolution approaches based on the use of multi-resolution and suitable basis functions for the problem unknowns. %D 2011 %K Microwave Imaging, Inverse Scattering, Multi-resolution techniques %T Multi-Resolution Approaches for Inverse Scattering Problems %L elediasc12352
