Recently, a method referred to as aperture partitioning was suggested to improve imagery of space objects collected through strong turbulence. In these situations the ratio of aperture diameter to atmospheric coherence diameters is large but, otherwise, images are reconstructed over a single isoplanatic patch size. Here, aperture partitioning has been shown to improve reconstruction quality in speckle imaging by reducing redundancy among imaging baselines. In this work, we explore the possibility of using aperture partitioning in horizontal imaging scenarios where the ratio of aperture to coherence cell size is small but imagery is highly anisoplanatic.
