The principle of synthesizing of the apertures is widely known and is effectively used in radar imaging systems [1–3]. The synthetic apertures enable to get a narrow radiation pattern (RP), that improves a resolution of the radar system. If in ordinary antenna systems the shaping of a RP occurs instantly and depends on mutual arrangement of radiating elements and parameters of their excitation, than in synthetic aperture the shaping of a RP is carried out in time by a relocating of the elementary antenna carrier and is provided by the appropriate spatial-time processing in the system.

Depending on the type of an antenna channel single-station radar systems and coherent multistation radar systems are distinguished. The mathematical simulation of such systems allows effectively to develop, analyze and optimize algorithms of a received radar information processing.
