Same-Beam VLBI in Lunar Orbiter Rendezvous and Docking
-
摘要: 针对“ 嫦娥5号”（CE-5）探测器间高精度相对测量需求，设计了我国深空干涉测量处理中心框架下的同波束VLBI处理算法，分析了X波段同波束VLBI相位解模糊条件和结果；通过引入群时延辅助的相位干涉技术，大幅抑制了干涉时延随机误差，为同波束VLBI中相位解模糊提供了先验条件；利用CE-5对接实测数据验证了本文工作的有效性，为CE-5任务同波束VLBI的实施奠定了基础。Abstract: To obtain a high precision relative measurement between the orbiter and the ascender of the CE-5 lunar probe, a same-beam VLBI algorithm is propsed in the framework of the deep-space interferometry processing center. The conditions and results of getting a right cycle ambiguity are discussed. After introducing the group-delay-aided phase interferometry,the random errors of interferometrical delay are suppressed greatly. It provides a priori condition for a right cycle ambiguity. Finally,the proposed algorithm is verified by using the CE-5 data,laying the foundation for the X-band same-beam VLBI in the CE-5 task.
