摘要
介绍了编队飞行卫星干涉合成孔径雷达(InSAR)测高的基本原理,在此基础上提出了编队飞行InSAR卫星系统顶层任务分析的基本要素和流程,分解出了测高误差分配、基线设计与测量、轨道构型设计、星间同步等关键技术,对各关键技术的相互关系及其基本解决途径进行了研究,并分析比较了不同InSAR载荷工作模式的性能及其与卫星系统的相互约束关系,可以为型号系统设计提供参考。
In this paper, we study the principle of spaceborne interferometric synthetic aperture radar （InSAR）, and then present the method and procedure of mission analysis and design of formation flying InSAR satellite system. On the basis of the presented method and procedure, we firstly list several critical technologies, for example, height accuracy analysis and assignment, baseline design and measurement, orbit configuration, synchronization among satellites, etc. , then analyze their relationship and present solution. Finally, on the basis of their performance and effects on technology implementation, we compare several operation modes of formation flying InSAR, and select an optimal mode for future project.
