Abstract: This report covers the studies of the characteristics of the scattering patterns from a subreflector of the modified monopulse dual reflector antennas. In this report, at first the basic computed formulas of the far-field sum and difference scatering patterns are deduced, and then the computed and measured results of the scattering patterns for the antenna of about 60 A diameters are obtained.By the analysis and experiment of the scattering characteristics of a subreflector of the monopulse antenna, a high sum efficiency and slope of secondary difference pattern can be obtained, using optically shaped reflector approach. Finally, the measured results of the modified cassegrainian monopulse antenna are given. -
