摘　　要：此次研制的双反射面天线,采用双曲抛物面设计副反射天线,同时联合优化喇叭的设计,在宽高比为7:1情况下实现整个天线的高增益和圆极化性能,并通过优化主反射面的设计形状,满足天线10%的工作带宽内方位低副瓣和仰角0~30°的余割平方覆盖。The double reflector antenna designed this time adopts a hyperbolic parabolic design for the secondary reflector antenna.Simultaneously optimize the design of the horn to achieve high gain and circular polarization performance of the entire antenna at a aspect ratio of 7:1,and by optimizing the design shape of the main reflector,antenna performance achieve the low sidelobe at azimuth and elevation coverage from O to 30 degree in according with conscant within 10%of the working bandwidth.
