补充资料：调频-调频遥测系统
采用调频-调频二重调制方式的频分制遥测系统,简称FM-FM遥测系统，属于模拟式遥测系统。FM-FM遥测系统的抗干扰能力强，遥测精度也比较容易得到保证。模拟式遥测系统大都采用这一类系统。下图为 FM-FM遥测系统的框图。各路被测量经变换器变换成电压信号后去控制各路副载波振荡器。副载波振荡器一般采用压控振荡器（即电压控制的振荡器），其振荡频率正比于控制电压,这样就实现了第一次调频。为了防止路际干扰,各路已调副载波先通过低通滤波器，滤去高次谐波，再送到相加放大器形成多路信号，并通过信道调制器对载波调频，这样就实现了第二次调频。已调频的载波由发射天线发送出去。接收端收到遥测信号后先通过解调器解调出多路信号，再送往各分路的带通滤波器，即分路滤波器，把各路已调副载波分离开来。分离出来的已调副载波送到相应的分路解调器，进行第二次解调，就可以得到所传送的模拟信号。美国对 FM-FM遥测系统已经实现了标准化、模块化、系列化。广泛应用模拟集成电路制成标准部件，提高了系统的可靠性和适应性。
