ALL-ROUND RADAR Russian patent published in 2019 - IPC G01S13/52 

FIELD: physics.

SUBSTANCE: invention relates to radar ranging, in particular, to radar stations of all-round view for detecting and determining the location of moving targets in the ultra-short wave range of electromagnetic waves (EMW), and can be used in air traffic control systems (ATC). Radar stations of all-round view has transmitting antenna-feeder device (TAFD), receiving antenna-feeder device (RAFD) of meter range, EMW, made with independent electronic scanning of airspace for transmission and reception. TAFD is connected by one high-frequency coaxial cable (SC) through the amplified probing signals with the power amplification device (PAD) of the probing signals. RAFD based on the reflected signals and radio interference signals is connected by another high-frequency SC with a multichannel receiving device installed in the radar stations hardware cabin. TAFD comprises flat reflectors installed vertically around the axis of the stationary non-rotating mast. Between two adjacent planes of reflectors two tier loop horizontal polarization dipoles are installed. RAS of the AFD comprises four identical tiers crossed in a horizontal plane of three half-wave horizontal polarization dipoles placed on a stationary vertical non-rotating mast.

EFFECT: technical result is reduction of weight and size characteristics of antenna system, increase of its reliability and service life without reduction of resolution of radar stations on range and azimuth for detection of aircrafts.
