In work the analysis of responses of system of processing trajectory signal of the radar system with synthesising of the aperture (SAR) is carried out at various kinds of moving of the phase centre of the real aerial. Responses are resulted for cases rectilinear and a rotary motion of the phase centre of the real aerial. On the basis of a principle of existential equivalence responses are analyzed both from a position of the theory of antenna lattices, and from a position of an optimum filtration of radio signals. Researches have shown that measurement of a trajectory of moving of the phase centre of the real aerial leads to change of the law of frequency modulation trajectory signal РСА that is equivalent to deformation of peak-phase distribution in synthesised aerials.
