Abstract An analytical approach to inverse electromagnetic scattering is tested on 2‐D experimental data. The closed‐form singular value decomposition of the scattering integral operator is the basis for determining the radiating components of the equivalent source density. This equivalent source is used to reconstruct the features of a scatterer. Reconstructions performed on different scattering data show the capabilities of the method and, thanks to the closed‐form solution, results are available after a very short time of computation. © 2013 Wiley Periodicals, Inc.
