摘要
分析了影响卫星数据地面接收系统交叉极化鉴别率的主要因素,提出了天馈系统的体系结构和设计方案。该方案已用于频率复用高码速率遥感卫星数据接收系统工程中,并成功实现了国内首颗双圆极化频率复用遥感卫星("资源三号"卫星,数据速率450Mbit/s×2)的数据接收。
The main factors that affect the system cross-polarization discrimination are analysed, the architecture and design of antenna and feed system are presented. Accordingly designed and realized system has successfully received data from ZY-3 satellite（China＇s first remote sensing satellite with dual circular polarization frequency reuse and data rate of 450 Mbit/s x 2）.
