In the following contribution an innovative strategy for the inversion of amplitude�]only data in microwave imaging applications is presented. The method consists of two steps. At the first step the source is synthesized in order to compute the incident field in the investigation domain. In the second step the profile of the object is reconstructed thanks to the iterative multi�]scaling approach combined to the Particle Swarm Optimiser, an innovative and effective evolutionary minimization technique. The effectiveness of the algorithm is preliminary assessed through the inversion of experimental data concerning an inhomogeneous dielectric scatterer.
