摘要
甚长基线干涉测量(VLBI)技术是近年来深空探测研究领域中的研究热点之一。VLBI技术具有测量精度高,作用距离远等优点,这些优点使其在当前及未来的深空探测项目中具有广泛的应用前景。通过对数十篇相关文献的调研,重点阐述了深空探测VLBI技术的基本原理、研究现状,并对该技术的关键技术及未来发展趋势进行了分析和研究,最后介绍了我国深空探测用VLBI技术现状及发展。
Very Long Baseline Interferometry(VLBI) technique is currently one of hot spot research topics in the domain of Deep Space Exploration.A main advantage of the VLBI technique is that it can track space probe in great far distance with tremendously high angular resolution.Taking this advantage,VLBI technique will be widely used in the future deep space Exploration missions.According to the investigation of a bibliography of several dozens papers,this paper presents a comprehensive review of the recent development and the basic principle of the VLBI technique for deep space Exploration,some analysis and discussion on research challenges and future directions in this field are also provided.And finally current situation and development trend of VLBI technique are briefly introduced.
