Remote sensing systems development permits to improve their informative parameters, i.e. increase probability of target detection/recognition, spatial resolution, etc. This paper deals with passive type of remote sensing systems or with radiometry imaging systems.

These modern systems require high spatial resolution that could be satisfied by two ways: 1) usage of improved antenna systems or 2) signal or image processing methods applications. Impact of antenna system on image formation quality is rather high though the influence of this system on parameters of image formation system in general.

Problem of aperture geometry impact on image formation process was investigated in [1] Therefore, in this paper problem of aperture field distribution and phase distribution influence on image formation/restoration will be considered.
