TL;DR: An inverse iterative algorithm for microwave imaging based on moment method solution based on Levenberg-Merquardt regularization technique with multiple illuminations of the target is presented here.
Abstract: An inverse iterative algorithm for microwave imaging based on moment method solution is presented here. This algorithm is based on Levenberg-Merquardt regularization technique with multiple illuminations of the target. It produces better reconstructed image of numerical model under noisy condition in comparison to that developed by our previous algorithms.

TL;DR: In this article, an inverse iterative algorithm for microwave imaging based on moment method solution is presented, where the stabilization term consists of a combination of three weighted discrete derivative operators instead of an identity matrix as in the Levenberg-Marquardt method.
Abstract: An inverse iterative algorithm for microwave imaging based on moment method solution is presented here. A modified Gauss-Newton method has been depicted here to address the nonlinear ill-posed problem. The stabilization term consists of a combination of three weighted discrete derivative operators instead of an Identity matrix as in the Levenberg-Marquardt method based algorithm developed by us. The present algorithm shows a marked improvement over the previous one in the quality of the reconstructed images from synthetic data under noisy condition.
