To improve the wide-angle scanning properties of the satellite antenna, we concentrate on the shaping of the main reflector of the Side-Fed Offset Cassegrain (SFOC) antenna by the method of the ray tracing and the idea of the optimization.

• 为改善星载天线的宽角扫描特性；采用射线追踪的方法；通过优化的思想对侧馈偏置卡塞格伦(SFOC)天线的主反射面进行了面赋形设计.
