Assuring a given active control of the phase and pointing errors, image reconstruction by optical aperture synthesis of capabilities of the Solar Ultraviolet Network (SUN) interferometer, are simulated. The importance of a compact array configuration when imaging extended objects is shown and selected results of marginal and diluted interferometric configurations are presented. It was found that if phase and printing errors are kept reasonable (10 deg, wavelength/6, and 10 marcsec) by the active control system of SUN, image dynamics of 1000 or so can be envisaged on most of the active and complex structures of the Sun.
