FIELD: radio engineering, communication.
SUBSTANCE: when processing the signal produces a shift of the signal in each channel ranges in frequency so that the Doppler frequency of the signals reflected from the elements, are on the chart beam spot axis directional antenna mappable surface becomes zero, and the formation of radar images produced conversion elements Doppler resolution for each channel range bins in the azimuth according to the azimuth dependence on Doppler frequency and range, return used with a frequency shift signal.
EFFECT: elimination of dark areas in the radar image obtained from several partial frames, caused by the curvature of the radiation pattern of the antenna on the spot when an electronic scanning the surface of the Earth.
