Application of NCP Parameter Choice Method on Inversion of Experimental Fresnel Data: TM Case

摘要

In This paper,the NCP parameter choice method is utilized for solving the 2-D TM inverse scattering problem. Born lterative Method and Tikhonov regularization technique are employed and the algorithm is applied to real data of two different profiles provided by Institute Fresnel. By using the NCP parameter choice method,the necessity for the computation of the SVD of the ill-posed matrix is obviated. Therefore,the computation and reconstruction time decrease efficiently,as well as an improvement of image resolution.
