Abstract : The patent relates to a monopulse radar antenna having an improved three-channel feedhorn for providing selectable polarization and greater target discrimination. The antenna feed employs a comparator having a difference port, a first sum port, and a second sum port utilizing a coupling pin or probe therein, between the comparator ports and an adjustable polarization device, for receiving and separating returned energy which has become cross-polarized with respect to the polarization of the transmitting sum arm, by reflection from an asymmetrical target. The three-channel feedhorn makes possible the identification of different types of targets, and the detection of hidden targets in rough terrain, forests, underbrush, and rough seas.
