摘要: 异地天线组阵可综合利用现有的天线设施,充分发挥设施资源的综合效能,对于我国未来深空探测任务的测控通信支持,提高测控通信距离,具有特殊的应用前景。介绍了异地天线组阵特点,并对异地天线组阵中关键的站间时延差修正技术进行研究,利用"嫦娥3号"下行数据开展技术试验验证,不仅获得了喀什、青岛、北京、三亚四站间的精确时延差结果,完成四站信号的基带合成和符号流合成,而且优化了软件相关器参数;该技术同时应用到欧空局"金星快车"微弱信号的基带合成处理中,为后续深空探测信号合成的工程化应用奠定了良好基础。

Abstract: In very long baseline interferometry (VLBI) system, remote multi-antenna arraying technique can be on the basis of the existing antenna facility and give full play to the overall efficiency of resources and infrastructure, which can expand the TT&C communication distance, and provide the TT&C communication service for China's future deep-space exploration mission, and will have a special application prospect. Firstly, we describe the features of remote multi-antenna arraying, and then study on the time-delay correction approach between key stations, using "Chang'e-3" downlink data to carry out the technological experiment. With this technique we get the precise time-delay difference values between Kashi, Qingdao, Beijing and Sanya stations, successfully implement baseband compound and symbol stream compound of the four stations' signals, and optimize the parameters of the software correlators. This technique has also been applied to process ESA's Venus Express weak signal baseband compound and laid a good engineering application foundation for future deep-space exploration signal compound.
