In clause are considered features of synthesizing of the aperture of the antenna at rotation of the phase center of the antenna and a mode of the review "under themselves". At carrying out of researches was considered, that object of supervision is the motionless dot purpose located strictly under the center of a circle, described at rotation by the phase center of the real antenna. The real antenna moves on a circular trajectory with constant radius of rotation, much smaller distances up to object of supervision, and with constant angular speed. The directional diagram of the real antenna is near-omni directional. Feature a signal in a considered case is periodic change of frequency, with the period equal to cycle time phase center of the real antenna around of an axis of rotation, process of synthesizing of the aperture of the antenna in time, limited by one period of rotation therefore is considered. The analysis of the target response of optimum system of processing a signal shows, that at the chosen trajectory of moving phase center of the real antenna is created bidimentional aperture having opened, allowing simultaneously to provide the high resolution, both on travelling, and on radial range, without application of special forms of probing signals.
