Abstract
Systems and methods that combine forward-model image reconstruction techniques with tomographic estimation of three-dimensional atmospheric turbulence to enable high-quality anisoplanatic imaging and beam control through the atmosphere over an extended field of view using a phased laser array. The system projects laser energy onto specific locations of extended objects in various geometries, overcomes atmospheric anisoplanatism and backscatter; estimates phase across the full aperture, and reconstructs the target object in great detail to enable high-resolution aimpoint selection and maintenance. Aimpoint maintenance is performed by sequentially analyzing a passive image and a laser spot in rapid succession, in each subaperture at high signal-to-noise ratio. As a further improvement, backscatter issues from the projected laser beam are eliminated by cycling the laser and/or sequentially lasing on different wavelengths within the laser gain bandwidth.
