摘要
介绍了两种目前在深空航天器导航中广泛应用的高精度干涉差分测量技术—差分干涉单向距离测量(ΔDOR)和同波束干涉(SBI)技术。从基本原理、观测方式和应用现状等方面比较分析了两种技术。详述了ΔDOR和SBI的相位整周解模糊和相关处理两个关键技术。系统地分析了误差来源,从共同误差因素和特有误差因素两个方面进行了分析总结。
Two high accuracy interferometric techniques-△DOR and SBI are described, which are widely used in deep space navigation. The two techniques are contrasted with each other from aspects of basic principle, observation ways and application status. Phase cycle ambiguity and correlation techniques, two key issues of ADOR and SBI, are discussed. The error sources are analyzed systematically and summarized as common error sources and private error sources.
