| Abstract: |
| The main factors that affect the system cross-pol
arization discrimination are analysed,the architecture and design of antenna and
fe
ed system are presented. Accordingly designed and realized system has succe
ssfully received data from
ZY-3 satellite(China′s first remote sensing satellite with dual circular polar
i
zation frequency reuse and data rate of
450 Mbit/s×2). |
