摘要
随着高速数字采集、大容量磁盘阵列记录和软件无线电技术的迅速发展 ,利用大容量磁盘阵列实现遥测数据实时记录已成为卫星地面接收设备的发展趋势。针对这一发展趋势 ,提出遥测数据事后分析处理系统 ,介绍其设计思想及组成结构 ,说明解调模块和帧处理模块设计及实现中涉及的关键技术。该系统能实现对记录遥测数据的事后分析处理 ,解决目前接收回放遥测信号设备使用。
With the rapid development of the technologies of high-speed sampling,large capacity disk array recording and software radio,recording the telemetry signal by large capacity disk array has been a trend.According to the trend,this paper presents the Post-processing and analyzing system of telemetry signal,introduces the design idea and structure of the whole software system,and discusses some key technologies about demodulation and frame synchronization of telemetry signal.The system realizes telemetry signal’s Post-processing and resolves the problem of high costs of receiving equipments.
