An analytical approach to location and shape reconstruction of dielectric scatterers, that was recently proposed, is tested against\r\nexperimental data. Since the cross-sections of the scatterers do not depend on the z coordinate, a 2D problem can be formulated.\r\nA closed-form singular value decomposition of the scattering integral operator is derived and is used to determine the radiating\r\ncomponents of the equivalent source density. This is a preliminary step toward a more complete solution, which will take into\r\naccount the incident field inside the investigation domain in order to provide the dielectric features of the scatterer and also the\r\nnonradiating sources. Reconstructions of the equivalent sources, performed on some scattering data belonging to the Fresnel\r\ndatabase, show the capabilities of the method and, thanks to the closed-form solution, results are obtained in a very short\r\ncomputation time.
