中频信号实时监测系统的设计与实现

Design and Realization of IF Signal Real-time Monitoring System

在卫星通信网中,卫星通信地球站中频信号监测主要依靠频谱分析仪,需要人工输入参数,记录链路状态,监测手段单一,工作量大,智能化程度低。针对此情况,给出了基于卫星通信地球站的中频信号实时监测系统的设计,介绍了系统的组成结构和功能,重点讨论了系统硬件电路和软件构架的设计过程,并对系统设计中的难点进行了分析。通过实际应用,验证了该系统的优异性能。

In satellite communications network, IF signal monitoring of satellite communication earth station relies mainly on spectrum analyzer, which requires the manual input of parameters to record link states. It lacks the variety of monitoring methods and thus involves heavy workload due to its low level of intelligentization. To address this problem, the paper presents the design of an IF signal real-time monitoring system of satellite communication earth station. It introduces the structure, functions and operating principles of the system, and particularly discusses the design of the hardware and software components, and analyses the difficult problems involved in the design process. The excellent capabilities of the system are verified by practical application.
