FIELD: radar ranging and radio navigation.
SUBSTANCE: invention can be used to solve tasks of radar monitoring of limited areas of Earth's surface of interest. Said technical result is achieved by direct synthesis of aperture in coherent processing of output responses of at least four transceivers. Transceivers are fixed around investigated object. Main beams of directivity pattern of a real antenna are directed to centre of observed area. Output responses are formed during time tarr, spent on operation of individual transmitter-receiver element with successive electronic switching thereof.
EFFECT: simplification of possibility of obtaining high-resolution image restricted on area of section of Earth's surface and reduction of costs for its obtaining.
