摘　　要：针对现代空空导弹,随着遥测参数需求的增加,遥测信号的码速率在不断提高。只有合理选取遥测系统的中频带宽,才能保证遥测系统的通信质量。本文对标准PCM-FM遥测信号的频谱特性进行了分析和仿真,给出了理论上最小中频带宽和工程应用中的选取方法。For modern air-to-air missile, the code velocity of telemetry signal were improved with the requirement of telemetry parameter. Only the intermediate frequency bandwidth of the telemetry system was selected correct, the communiation quality could be ensured.The frequency characteristic of assuring standard PCM-FM telemetry signal was analyzed and simulated. The least intermediate frequency bandwidth of theory and the selected method of engineering application were provided on this paper.
