摘要
针对应答机采用不同的接收信号功率控制方式，对下行测距调制度、残留遥控调制度以及转发噪声调制度的情况进行了理论分析，得到了各种情况下的调制度数学模型，可供读者在航天工程的测控链路设计及应答机设计时参考。
This paper analyzes theoretically the downlink ranging, residual command and turnaround noise modulation indices of the transponder according to the different control modes fot its received signal power. And the mathematical models are set up for modulation indices under various conditions, so it can be provided to readers as reference for TY＆C link design and transponder design in aerospace project.
