A new technique for microwave imaging of three-dimensional dielectric targets is presented in this paper. The underlying inverse scattering problem is solved by using a multi-resolution strategy, able to iteratively focus the inversion on the regions containing the targets, combined with an efficient regularization procedure based on an inexact-Newton algorithm. Some preliminary results and comparisons with existing techniques are reported.
