Abstract
Starting from the iterative multi�]scaling approach developed for monochromatic illuminations, two multi�]resolution strategies have been studied for dealing with multi�]frequency inverse scattering experiments. The first approach is based on a multi�]scaling frequency�]hopping reconstruction scheme, while the second one is concerned with a simultaneous multi�]resolution processing of multi�]frequency data. In this contribution, a comparative assessment is performed by means of a set of representative experiments in order to evaluate the reconstruction accuracies of the proposed implementations also in comparison with the monochromatic multi�]step process.
