Reconstruction of permittivity distribution using the Born iterative and distorted Born iterative methods for geophysical applications

The effect of the limited angle measurements on the nonlinear inverse scattering problem has been investigated. Because of the sparsity of measurement data for this problem, the quality of the reconstruction has been considerably reduced, and sometimes it is almost impossible to reconstruct the profile. To overcome the this difficulty, a boosting procedure which helps to obtain maximum information for an arbitrary predefined experimental setup is proposed. The results of the computer simulation demonstrate that the boosting procedure plays a very important role in the application of the nonlinear inverse scattering algorithms to geophysical explorations.link_to_subscribed_fulltex
