Abstract

A new approach to constructing globally convergent algorithms for the approximate solution of some coefficient inverse problems arising in electromagnetic frequency sounding is presented. Utilizing the original transformations developed for the convexification method, this approach possesses two disctinctive features: (1) Bregman iterations, and 1) the refinement with the interior data. These novelties may significantly enhance both the spatial and contrast resolutions of quantitative imaging. These algorithms can be applied to quantitative imaging in GPR and marine CSEM sounding. Some results of computational experiments are presented.
