摘要
为更好地开展深空无线电干涉测量试验,基于DiFX(Distributed FX,分布式FX型相关处理)、SPICE(Spacecraft Planet Instrument Camera-matrix Events,航天器行星仪器照相机矩阵事件)、HOPS(Haystack Ob-servatory Postprocessing System,Haystack克天文台后处理系统)及AIPS(Astronomical Image Processing Sys-tem,天文图像处理系统)等开源软件,搭建了一套可用于深空探测器信号相关处理的无线电干涉测量数据处理系统.首先介绍了该系统的整体架构及组成,然后介绍了系统各组成模块的功能及工作原理,最后利用该系统对嫦娥三号着陆器开展了观测试验,并对观测数据进行了处理.试验结果表明,该系统能成功实现深空航天器信号的相关处理、条纹拟合,以及时延解算等功能,有望为我国嫦娥五号任务及火星探测任务数据处理提供支持.
Abstract
A suit of radio interferometry data processing system based on open source software such as Distributed FX (DiFX),Spacecraft Planet Instrument Camera-matrix Events (SPICE),Haystack Observatory Postprocessing System (HOPS)and Astronomical Image Processing System (AIPS)used for data correlation processing of deep space detector signals has been built to carry out a better radio interferometry experiment.Architecture and composi-tion of the system were introduced and operational principle and functions of each module were de-scribed.Observations with Chang'e-3 lander were made and experiment data was processed using the data processing system.The results show that the system realizes the functions of correlation processing,fringe fitting and time-de-lay estimation for deep space detector signals,validating capability of the system to provide support to data process-ing in China's Chang'e-5 mission and Mars exploration missions.
