FIELD: physics.
SUBSTANCE: invention relates to on-board radar stations with a phased antenna array meant for forming a radar image of the monitored area of the earth's surface and objects on the surface in range-azimuth or elevation angle-azimuth coordinates in real-beam mode during low-altitude flight of an aircraft carrying the radar station, as well as on-board infrared radar stations, which receive and amplify a radiated thermal signal in the radar wavelength range. The method of increasing resolution of a phased antenna array of an on-board system involves formation of a beam pattern of the phased antenna array for a given angular direction, characterised by that based on the set of signals received by all channels of the phased antenna array, reflection or radiation field components are selected with increase in angular resolution by several times.
EFFECT: high angular resolution of a phased antenna array in real-beam mode.
