摘要
介绍了基于地基合成孔径雷达干涉测量技术的微变形监测系统(IBIS-L)的工作原理和关键技术,通过对建筑物的监测数据的分析和处理,得到了在雷达视线方向优于毫米级精度的形变结果,实验表明,IBIS系统可以实现高分辨率、高精度、实时的建筑物变形监测。
The basic theoretical principles and key techniques of the IBIS-L system were proposed by means of the ground-based synthetic aperture radar interometry.It was obtained better than milimeter deformation results by analyzing and processing the monitoring data of the building.the test results indicate that：the IBIS-L system can be employed to monitor real time deformation of building with high spatial resolution and accuracy.
