摘　　要：文中论述了微波着陆系统扫描天线的方向图,介绍了泰勒分布线源激励电流的计算方法,设计了泰勒分布相控阵天线方向图计算综合程序,用该程序计算并分析了微波着陆系统方位台扫描天线的H面方向图以及移相器故障和量化误差对方向图产生的影响。该程序的设计为微波着陆设备相控阵天线的后续研制提供了理论依据和参考。The radiation patterns of scanning antenna in microwave landing system is illustrated in this paper, the method of calculating exciting current of Taylor pattern array is introduced. An calculation program which calculated the radiation patterns of linear phased taylor pattern array is designed. The directions in the H plane of scanning antenna in azimuth station is analysised by this program, and the effects of the uantization error and fault of phase shifter on the radiation patterns are considered. The theory according and reference is given by the program for the research of the phase array in Microwave Landing System in the future.
