Abstract
The article analyzes the radar trajectory signal with the synthesis of the aperture during the rotation of the phase center of the real antenna in the case of observation of a ground moving target. It is shown that in contrast to the observation of moving targets in the rectilinear motion of the antenna, there is a significant defocusing of the response due to the appearance of linear frequency modulation in the reflected signal. Partial compensation of the target motion is possible using the algorithm of Doppler frequency estimation.
