摘　　要：针对遥测设备失锁段落时码散乱、时码和数据的对应关系不正确的问题,提出了基于数据与时码分离存储的遥测时码修正方法。该方法利用帧计数线性递增的特点,修正了异常帧计数和时码,解决了遥测数据和时码不一一对应的问题。实测结果表明,该方法解决了异常时码对数据配时的影响,增加了特征时刻遥测数据可用量,可提高遥测数据事后处理精度。In order to solve the problem that the correspondence between time code and data is not correct when the telemetry equipment is out of lock,the method of telemetry time code correction based on the separate storage of data and time code was proposed.This method used the feature of linear increase of frame count to correct abnormal frame count and time code,which solves the problem that the telemetry data and the time code do not correspond one by one.The measured results show that this method solves the impact of abnormal timing code on data timing and increases the available telemetry data at the characteristic time,which can improve the post-processing accuracy of telemetry data.
