Abstract: Two-dimensional reconstruction of images of space objects by a nonlinear iteration method is considered. To obtain a high-quality image reconstruction of the source surface with active formations, three kinds of a priori information are used. This is the angular size of the source, its average brightness temperature and the nonnegativity of the iterative solution. The extreme resolution is limited by the spatial discreteness of image recording.
