摘    要:本文用物理光学法分析研究任意极化单脉冲环焦天线的近场分布和远场方向图.利用傅里叶级数展开公式,将四重积分分别简化为三重(近场)和二重积分(远场),大大简化了数值计算.实验结果证明了理论分析的正确性,数学模型和分析软件可用于大中型双赋形单脉冲环焦天线设计.

关 键 词:单脉冲  环焦天线  近场分布  远场方向图  极化

Abstract:In this paper,the P.O.method is used to predict the near field and far field of a monopulse ring focus antenna with arbitrary polarization.By use of the Fourier series expansion,the radiation integral is simplified,respectively,from four dimensions to three dimensions for near field or two dimensions for far field.The formulae and codes developed have been tested by an experiment,and good agreement has been obtained.
Keywords:monopulse  circular ring  focus  near field distribution  pattern  polarization
