METHOD FOR PRODUCING RADIOLOCATION IMAGE OF EARTH SURFACE BY MEANS OF USING MULTI-POSITIONAL RADIOLOCATION SYSTEM WITH SYNTHESIZED APERTURE OF ANTENNA Russian patent published in 2006 - IPC G01S13/90 

FIELD: radio engineering, in particular, engineering of remote probing systems, meant for producing high detail radiolocation images of earth surface.

SUBSTANCE: observed portion of earth surface is irradiated by orthogonal signals from N transmitters. In coherent accumulation spectrum, simultaneous receipt of reflected signals and direct expansion signals is performed for each one of N transmitters, from direct expansion signals of each one of N transmitters, ephemeris information about its carrier is singled out, and also information about onboard time scale and parameters of ionosphere, with consideration of aforementioned information, pair-wise mutually correlating processing of received signals is performed, simultaneously N independent radiolocation images from different angles are synthesized.

EFFECT: increased interference resistance of functioning system, increased information capacity of system, improved quality of resulting radiolocation image of observed portion of earth surface.
