| Abstract: | 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. |
