摘要
针对目前我国InSAR系统中定位定姿设备精度不高的现状,提出了一种基于地形匹配的地形变化检测方法。该方法是InSAR数据应用于地形变化检测的一种新途径,能够在InSAR系统直接定位精度不高的情况下,提高地形变化检测数据处理的自动化程度。
This paper studies the situation of the lower accuracy of Position and Attitude Measurement Device in InSAR system and puts forward a method of topographic change detection base on terrain matching. This is a new method in topographic change detection with InSAR data. It can improve the degree of automation data processing in topographic change detection with poor Direct Georefereneing of InSAR system.
