船载测控雷达高频接收机无人值守功能的设计

Design of the unattended function for RF receiver of Ship-borne TT&C radar

摘要:

随着我国航天测控事业的发展,在轨航天飞行器数量逐年增加,陆地测控站已经由原来的人工操作模式过渡到自动化运行模式。但是在日常工作中,船载S频段测控雷达高频接收机仍需频繁借助人工进行本地开关机,并且在跟踪飞行目标过程中需要人工进行现场识别并设置信号工作频点,存在时效性差和工作效率低的问题。为解决此问题,设计一种设备远程加去电和飞行目标极化判断、频点自动识别设置系统。该系统采取非侵入式,可在常态化任务和海上测控任务中进行灵活切换,不影响系统原有工作方式。该系统基于LabWindows/CVI环境平台控制网络继电器和频谱仪实现了高频接收机的远程加去电、目标信号自动搜索捕获和跟踪旋向和点频设置,提高了船载测控站完成常态化任务的时效性和可靠性。

Abstract:

With the development of China’s aerospace industry, the number of in orbit spacecraft has been increasing year by year, working mode has been transmitted from manual operation to automated operation for land measurement and control station. It needs to turn on or turn off by manual work for HF receiver of Ship-borne TT C S-band radar in daily work. Also it needs to identify and set signal frequency point locally in tracking spacecraft which resulted in the shortcoming of timeliness and work efficiency low. In order to solve the problem, a design is given by this paper about a remote device for powering on/off and polarization judgment of flight targets, as well as an automatic frequency identification system. The system is non-invade. It can switch flexibly between normalized tasks and maritime measurement and control and does not affect the original working mode of the system. It is developed based on LabWindows/CVI platform, which realize the function of remote electric, acquire and set signal frequency point automatically by controlling network relay and spectrum analyzer. The result shows that the system improves the timeliness and reliability of Ship-borne TT C station in daily work.
