Regularized image reconstruction in the electromagnetic geotomography through the use of the Wiener filter

摘要

A method of regularization of the reconstructed image in electromagnetic geotomography is proposed. The Wiener filter for attenuating the noise disturbance in the reconstructed images is used with Landweber iterations. The results of the reconstruction from measured data both with and without filtering are shown. The efficiency of the proposed regularization technique is discussed.
