摘　　要：讨论了用主反射面偏转进行扫描的毫米波小口径双反射面天线,并利用射线法分析了其扫描性能。射线法简单而有效,对任何形状和位置的反射面皆适用。数字实验结果表明,射线法是相当有效的。The MM—Wave small—aperture scanning dual—reflector antenna,which can scan a large angle—scope by rotating the main—reflector,is discussed in this paper, and the SBR method is used to analyse its scanning capacity. The SBR method is so simple in concept that there is virtually no restrication on the shape or place of the scanning antenna. Numerical results obtained show that the SBR method is very efficient.
