摘　　要：在各种航天器飞行过程中的测控,需要运用测控雷达的统一载波信道,来完成对航天器的遥控、遥测、跟踪测量、通信等活动。统一载波信道中的频带较宽,所以在该信道中能够进行多种遥控、遥测、跟踪测量、通信等信号的调制,从而实现对各种航天器飞行过程的测控。针对统一测控系统存在的测距值错误、遥控指令、信号干扰等情况,通过频谱分析仪对多个副载波信号进行分析,来提出信号调制故障的解决对策。in the process of measuring and controlling all kinds of spacecrafts, we need to use the unified carrier channel of TT C radar to accomplish remote control, telemetry, tracking, measurement, communication and other activities for spacecraft. The frequency band of the unified carrier channel is wide, so in this channel, we can modulate various signals such as remote control, telemetry, tracking, measurement and communication, so as to realize the measurement and control of various spacecraft＇s flight process. Aiming at the problems of ranging error, remote control instruction and signal interference existing in the unified measurement and control system, we analyze multiple subcarrier signals by spectrum analyzer, and propose solutions for signal modulation faults.
