Interferometric method for image formation: the basic ideas and computer simulation
As it is known, the key resolution limit of an astronomical instrument is determined by diffraction of a received wave on the instrument aperture. However, by performing observations from the Earth surface in a short-wave part of the wave band, it is seldom possible to achieve this limit because of...

There is a series of ideas how to form an astronomical image decreasing or excluding the influence of phase distortions during the observation. One of such methods is the interferometric imaging method.
