Abstract

Recently developed coherent-imaging algorithms using Model-Based Iterative Reconstruction (MBIR) are robust to noise, speckle, and phase errors. These MBIR algorithms produce useful images with less signal which allows imaging distances to be extended. So far, MBIR algorithms have only incorporated simple image models. Complex scenes, on the other hand, require more advanced image models. In this work, we develop an MBIR algorithm for image reconstruction in the presence of phase errors which incorporates advanced image models. The proposed algorithm enables optically-coherent imaging of complex scenes at extended ranges.
