METHOD FOR SHAPING RECEIVING DIRECTIVITY PATTERNS OF SINGLE-PULSE ANTENNA COMBINATION AND SINGLE-PULSE ANTENNA COMBINATION

摘要

FIELD: radio engineering; radar systems using single-pulse method to detect target coordinates; phased antenna array combinations.;SUBSTANCE: proposed single-pulse antenna combination implementing proposed method has phased antenna array incorporating three separate identical apertures and comparator; phase centers of phased-array separate identical apertures are disposed in vortices of equilateral triangle placed in aperture plane of phased antenna array and outputs of pattern-forming circuits of separate apertures are connected to inputs of three circular dividers of comparator; first outputs of first and second circular dividers are connected to respective inputs of first circular bridge; second output of second circular divider and first output of third circular divider are connected to respective inputs of second circular bridge; second outputs of first and third circular dividers are connected to respective inputs of third circular bridge; all outputs of circular bridges are connected to respective inputs of beam adder.;EFFECT: reduced static bearing-detection error in two relatively orthogonal direction finding planes (azimuth and elevation) relative to direction finder construction line.;2 cl, 4 dwg, 2 tbl
