FIELD: radio engineering, communication.
SUBSTANCE: method of forming a three-dimensional image of the earth's surface in an on-board four-channel Doppler radar set includes determining spatial coordinates of reflecting surface elements situated in range resolution elements and Doppler frequency, and is based on combined application of selection on Doppler frequency and a phase method of measuring coordinates.
EFFECT: forming a three-dimensional image of a surface in the visibility range of a radar station in the form of a set of spatial coordinates of reflecting elements of the surface with high accuracy of determining coordinates and wider visibility range of the radar station.
