Validation of 2d iNverse Scattering Algorithms From Multi-Frequency Experimental Data

摘要: Reconstructions of two dimensional dielectric or conducting objects from multi-frequency experimental data are considered in the present paper. Two different iterative methods used for solving inverse scattering problem. The first one is based on a boundary integral formalism and retrieves boundaries complex permittivities unknown homogeneous scatterers. For this method initial guesses derived decomposition time reversal operator (DORT) combined with low frequency approximation. second domain relative permittivity distribution inside some investigated domain. were carried out controlled environment (anechoic chamber) reconstructions have been performed using multifrequency approach, i.e., scheme starts lowest available uses final result as guess at higher order to enhance resolution.
