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。
Aiming at the current situation that the accuracy of positioning and orientation equipment in InSAR system is not high, a terrain matching detection method based on terrain matching is proposed. This method is a new way of applying InSAR data to the detection of topographic changes. It can improve the automation of data processing of topographic changes with the direct positioning accuracy of InSAR system.
