Abstract: In this paper, we propose a novel amplitude-comparison monopulse receiver architecture for ultra-wideband radars. This monopulse receiver consists of four ridged-horn antennas placed in a square-feed configuration, a comparator circuit that generates the monopulse sum and difference signals, cross-correlation receivers that detect the monopulse signals, and an amplitude-comparison monopulse processor that determines the target's angular position. The derived monopulse sum and difference signals are verified through measurements. The derived sum and difference patterns are compared with measured patterns, and they show good agreements - measured 3-dB beamwidth = 6.4°(derived = 6°), measured unambiguous tracking range = ±5°(derived = ±5°), and measured sum pattern sidelobe level = -6 dB (derived = -8 dB). © 2006 IEEE.
