Sheared beam imaging (SBI) is a coherent active imaging technique that employs a pupil-plane phase difference measurement approach to overcome the perturbing effects of atmospheric turbulence. The technique has shown promise for applications such as imaging satellites from ground-based sites. However, atmospheric compensation is dependent on the effective atmospheric isoplanatic patch size; which mines that degradations can occur for larger objects. We present theory and simulation results that demonstrate this limitation and we suggest approaches to reduce the residual degradations caused by anisoplanatism. Our simulations use wave optics propagation through phase screens to model atmospheric turbulence effects.
