| 摘 要： | 针对＂神舟＂飞船测控跟踪功能没有备份的难题,首次提出利用FM（调频）跟踪接收机跟踪接收数传信号来实现跟踪功能备份。从数传信号调制特性、FM跟踪接收机组成及载波接收解调3个方面进行了理论分析,并通过FM跟踪接收机的数传信号接收解调、静态跟踪和动态跟踪试验验证了该方案的可行性和有效性。该技术在不增加辅助设备功能的基础上,通过船载测控设备中FM跟踪接收机来实现对飞船跟踪功能的备份,显著降低对飞船目标跟踪失效的风险。

| Abstract: | This paper proposes the use of FM(Frequency Modulation) tracking receivers to receive data transmission signals from Shenzhou manned spaceships as a backup means for the spaceship tracking system.Feasibility and validity of the design is theoretically demonstrated from data transmission signal modulation characteristics,composition of FM tracking receivers and carrier reception and demodulation,and through reception and demodulation,stationary tracking and dynamic tracking tests.The FM tracking receivers successfully meet redundancy requirements for tracking of spaceships without additional auxiliary equipment. |
