Compensation of turbulence in atmospheric imaging is usually hampered by the lack of a reference point source. We consider the possibility of phase compensation based on the reference wave scattered by the rough surface of an object under review. Analysis has been made on the basis of numerical simulation. The recently developed method for incoherent imaging through the atmosphere in anisoplanatic turbulent conditions allows simulating both long-exposure and short-exposure images. We analyze the influence of the size of object reflecting reference wave on the efficiency of phase compensation. Image quality enhancement is observed for the object size significantly exceeding the diffractivelimited size with respect to the receiving aperture. Also we consider the features of phase compensation with the reference wavelength different from visible light ones.
