| 摘 要： | 针对目前使用的多站遥测数据实时处理模式，分析了其存在的弊端，在此基础上提出了遥测数据解密前进行多站遥测数据实时对接的设想，并研究了多站遥测数据实时对接方法的可行性和正确性。此方法采用理论弹道对遥测帧时间进行电波延迟修正，从而实现了按时间对齐遥测全帧的目的，并通过采用全帧检择的办法，对接形成了一个数据质量较好的遥测流。

| Abstract: | The real-time processing mode of multistation telemetry data currently in use is analyzed and its disadvantage is sum-marized.Based on this analysis,the idea of multistation real-time docking of telemetry data before telemetry data decryption is put for-ward,and the feasibility and validity of real-time docking method of multistation telemetry data is studied.This method uses the theoreti-cal trajectory to conduct telemetry frame time radio wave delay correction, thus realizing full-frame telemetry alignment according to time,and through the use of full-frame detection approach,a better-quality telemetry stream is formed by final docking. |
