Abstract

This work deals with the solution of highly nonlinear inverse scattering (IS) problems. Towards this end, an innovative microwave imaging (MI) method based on the integration of the Contraction Integral Equation for Inversion (CIE-I) method with the iterative multi-scaling approach (IMSA) is proposed. Accordingly, robust multi-resolution MI of large and/or strong scatterers is achieved thanks to the effective combination of the capabilities of the CIE-I to alleviate multiple scattering contributions with those of the IMSA, which mitigates the non-linearity of the IS problem by keeping as low as possible the ratio between unknowns and informative data. A numerical benchmark is shown to assess the proposed method and to compare it against a state-of-the-art single-resolution technique.
