摘　　要：为保证数据录取率,弹道飞行试验任务的遥测一般都采用多站备份接收或多站接力接收,因此,多站接收的遥测数据需要进行事后拼接,形成一个遥测数据最完整的文件。各站原始遥测数据文件格式多样,而且存在配时差异,丢帧、失锁等现象也时有发生。为此需要将多站数据进行整理,继而完成精确拼接。主要过程为:统一格式、丢帧插补、时差修正、分段择优、拼接及检查等。在试验中应用该方法,提高了数据录取率和数据处理效率。In order to ensure the data acceptance rate, the telemetry data are generally received by the method of multi-station backup or multi-station relay in telemetry of trajectory test. So the multi-station telemetry data that received by every station need to be spliced after the event, to form the most complete data file. The file formats of original telemetry data from each station are diverse, there are differences in timing, and frame dropping, lock-lose and other phenomena also occur. Therefore, the multi-station data need to be arranged to complete the precise splicing. The main process includes format unification, dropping frame interpolation, time difference correction, subsection optimal selection, splicing, inspection and so on. This method is applied in the test and the result shows that the data acceptance rate and data processing efficiency are improved.
