Radar Antenna.
Abstract
An antenna for range-gated, pulse doppler, radar systems. The antenna includes first and second, shortened, half-wave dipoles and first and second reflecting screens. One dipole is fed through a fixed 22 1/2 degree phase-shift network while the other is fed through a 45 degree phase-shift network that can selectively be switched in and out of the feed circuit. A counter which uses a shift register with linear feedback which is connected to generate a maximal length pseudo-random sequence. When a given state in the sequence is sensed, certain shifts are inhibited, and the register is returned to the all-one state. (Author)
