用软件实现遥测数据事后帧同步和定时处理

在多目标遥测系统中 ,实时对每个目标的视频遥测数据进行帧同步、定时处理 ,其硬件成本高 ,且定时延迟不确定。随着计算机处理速度的提高 ,可以将经过码同步处理的数据和遥测定时信息实时记录 ,事后用软件对实时记录的遥测数据、定时信息进行处理。提出一种多目标遥测系统实时记录数据帧同步处理、B0 0 0码解码、插入遥测定时的软件实现方法 ,该方法降低了遥测系统的硬件成本 ,提高了遥测定时精度

Frame Synchronization and Timing Processing for Telemetry Data after Event by Software

In a multi-target telemetry system,hardware approach to process video telemetry data of every object in real time is expensive and the delay of timing is uncertain.In accordance with the development of the high speed computer,it is possible to record the telemetry video data and the timing information in real time,and then to process record data after the event by software. a Software method is proposed for realtime tlelmetry data in a multiple target telemetry system to implement the frame synchronization processing,the decoding of B000 code,the insertion of telemetry timing.The implementation of such a manner has decreased the expense for telemetry hardware and improved on the precision of timing.
