This study presents a modified method based on the enhanced distorted Born iterative method for solving the 2D inverse problem. The proposed method overcomes two shortcomings of the enhanced distorted Born iterative method: (i) the regularisation parameter has to be determined artificially beforehand; (ii) The effects of the two regularisation processes in the enhanced distorted Born iterative method are redundant. The synthetic numerical reconstruction results, as well as the experimental reconstruction results, show that the proposed algorithm is capable and efficient for solving the 2D inverse scattering problem.
