Nonlinear Iterative Hard Thresholding for Inverse ScatteringAnna C. Gilbert, Howard W. Levinson, John C. Schotland
We consider the inverse scattering problem for sparse scatterers. An image reconstruction algorithm is proposed that is based on a nonlinear generalization of iterative hard thresholding. The convergence and error of the method was analyzed by means of coherence estimates and compared to numerical simulations.
