Regularized Bi-Conjugate Gradient Algorithm for Tomographic Reconstruction of Buried Objects

摘要

This paper deals with a quantitative inversion algorithm for reconstructing the permittivity and conductivity profiles of bounded inhomogeneous buried objects from measured multifrequency and multiincidence backscattered field data. An Edge-Preserving regularization scheme is applied leading to a sig- nificant enhancement in the profiles reconstructions. The appli- cations concern civil engineering and geophysics as well as mine detection and localization. The performance of the reconstruc- tions are illustrated with different synthetic data.
