FIELD: radio engineering, communication.
SUBSTANCE: disclosed method includes forming, on a given synthesis time interval, a radar image of a portion of the earth's surface in the form of a set of complex amplitudes of reflection signals in range resolution elements at Doppler frequencies simultaneously in four measurement channels, the method being characterised by that for every four amplitudes of corresponding image elements obtained at the same frequency, angular coordinates of the corresponding surface element are measured using a monopulse method and said angular coordinates are converted into Cartesian coordinates of the antenna system.
EFFECT: measuring coordinates of elements of the earth's surface while forming a three-dimensional image of the surface in the visibility range of the radar set.
