A computing method of image reconstruction of scatterer
2010
A computing method of image reconstruction of 2D lossy EM dielectric medium is developed. We adopt the nonlinear least squares method to process the inverse problem. Tikhonov regularization is used to get the iterative equations, then the iterative equations are discretized in the form suitable for numerical calculation, and eventually the two electromagnetic parameters of scatterer are obtained. Simulation results show that this method can not only achieve the spatial orientation of the scatterer, the electromagnetic parameters of the inversion of the scatterer also can meet the precision requirements.
