Analysis and Design of Multimode Feed Horn for Monopulse Radar
摘要
Abstract
The theory and design of a feed with four horns and three modes is analyzed in detail in the paper. The changes of mode ratio and the horn aperture phase non-uniform distribution can bring about effects on the feed pattern. Considering the above factors, the analytic expression of feed pattern is provided through strict derivation. According to the result, the effects of frequency and mode ratio on the feed pattern are analyzed and the optimal mode ration of the feed is designed. The perfect sum and difference pattern is showed. The phase center of the feed is analyzed. The effects of frequency and phase distribution on phase center are given. These conclusions have certain instructional significance to engineering design.关键词
