摘　　要：本文对偏馈赋形紧缩场天线设计进行系统研究．提出一种新的偏馈双反射器天线几何光学综合的方法．该法便于理解、推导和用计算机作数值计算。文中提出了一种计算紧缩场交叉极化的新技术。经深入分析，得出了若干具有普遍性的结论。讨论了赋形紧缩场工程设计中的一个重要问题──交叉极化与绕射效应间的矛盾，并由此阐明了布局优化的重要性。The design of offset feed shaped compact antenna test range is studied systematically. A new method of the geometrical optical synthesis of dual offset shaped reflector antenna is developed. This method can be easily understood and developed,and used in numerical calculation. A new technique used to calculate the cross polarization of compact antenna range is also developed. Several universal conclusions are obtained for cross polarization. At last,the contradiction between cross polarization and diffraction,an important problem in the design of shaped compact antenna range, is discussed.Then the significance of antenna configuration optimization is clarified.
