Design of Data Receiving System for Frequency Reuse High Data Rate Remote Sensing Satellites

To solve the key technologies of dual circular polarization frequency reuse and high data rate reception,this paper analyses the main factors that affect the system cross-polarization discrimination and the error performance of high data rate receiving link,proposes the architecture and design of antenna and feed,high data rate receiving link.Accordingly designed and realized system has successfully received ZY-3 satellite(China′s first remote sensing satellite with dual circular polarization frequency reuse and data rate of 450 Mbit/s×2) data.
