An adaptive imaging algorithm for microwave diffraction tomography

Abstract

A numerical method for image reconstruction using electromagnetic diffraction tomography is presented. An adaptive algorithm is proposed for the reconstruction of the complex permittivity of an inhomogeneous lossy dielectric object having arbitrary shape. Starting from integral representations of the scattered electric field and using the moment method, an algorithm based on LMS is applied to the two dimensional problem. Some results of the simulated data are presented. Finally the authors show that successful results can be obtained with this adaptive reconstruction algorithm. >
