        abstract = {A set of representative results are presented that are obtained with two multiresolution strategies developed for dealing with multifrequency inverse scattering experiments starting from the iterative multiscaling approach previously studied for monochromatic illuminations. The first approach is concerned with the integration of the iterative multiscaling algorithm into a frequency-hopping reconstruction scheme, while the second one allows a multiresolution simultaneous processing of multifrequency data. The numerical and the experimental analysis are aimed at assessing both the reconstruction effectiveness and the required computational costs of the two- and three-dimensional implementations of the proposed inversion schemes in comparison with the monochromatic multistep process and to the single-step optimization strategy, as well.
