摘要
文章从实例出发,介绍了C/Ku频段卫星地面接收系统的设计方案。首先,介绍大、中型地面站的站址选择;然后,对接收系统构成及工作原理作了详细阐述;为保证系统接收质量,对卫星下行链路载噪比C/N、每比特信息能量与噪声功率密度之比Eb/N0、信号的功率电平等技术参数进行估算;进而说明系统设计的合理性。
This paper proposes a scheme for C/Ku waveband satellite ground receive system. It first gives a method for how to locate the ground station, then describes the system structure, including the estimations of such parameters such as Eb/N0, downlink carrier to noise ratio and the electric level distribution, thus to prove the design＇ s rationality.
