Abstract: The Born iterative method is used to solve the nonlinear inverse scattering problem for two-dimensional dielectric inhomogeneity using time-domain data; three order difference regularization is applied to improve the inversion process; and a general selecting regularization parameter is developed.

Key words: dielectric iamging, Born iteration, time-domain optimization
