本文在分析和推导了具有不同波段转发器相互交链的ＳＣＰＣ／ＤＡＭＡ卫星通信系统的频差的数学模型的基础上，提出了一种系统校频的方案，并较详细地分析了其操作过程。
In this paper, based on the analysis and deduction of the mathematical model of frequency difference of SCPC / DAMA satellite communication systems with different transponders of different wavebands, a scheme of system frequency calibration is proposed and its operation process is analyzed in detail .
