FIELD: radio engineering, communication.
SUBSTANCE: antenna post has a periscopic hybrid mirror antenna with drives, a parabolic reflector with a polarisation filter, which interacts with a flat subdish, and a transmit-receive radiator. Each of the transmit-receive radiators has a pair of channels. The number of pairs of even and odd type received beams in the antenna fan with a small-component antenna array is one beam pair less than the number of radiators.
EFFECT: simple design of the antenna post, high speed of scanning space and accuracy of measuring coordinates, enabling scanning of space in the entire top hemisphere, enabling formation of a fan of received mono-pulse beams in the vertical plane and detecting targets simultaneously on all beams forming the fan.
