摘　　要：运载火箭遥测数据处理首次运用于海上测控任务中,针对船载设备接收原始遥测事后数据包含许多无效的乱码且记录数据十分庞大、需要在短时间内进行数据处理的难题,首先介绍了遥测数据预处理原理,对预处理方法进行了研究,最后提出了用正则表达式算法将原始数据从庞大的数据帧中解算出来的预处理模式,在短时间内完成了数据的预处理工作,提高了处理效率,解决了遥测数据处理的关键技术问题。Telemetering data preprocessing of carrier rocket handle is first appied in the ship for tracking and control- ling. Aiming at the shortcoming of original telemetering data including many invalid disorderly code of the record data is very huge and need to preprocessing on the equipment of measurement ship in a short time, first the telemetering data preproeess- ing principle is introduced, the method of preprocessing is researched, finaUy the preprocessing mode is put forward to use regular expressions calculate original data from the huge data frames. In a short time, the work of data preprocessing is com- pleted, processing efficiency is improved, and the key technique problem of telemetering data processing is solved.
