Abstract：The micro deformation monitoring system based on ground-based synthetic aperture radar interferometry is an innovative radar system that is capable of continuous and comprehensive real-time monitoring. According to the composition, working principles and the key technology of IBIS-L system, we analyze and process long time monitoring data of a large-scale hydropower slope. The deformation monitoring accuracy is compared with TM30 total station. Experiments show that, the deformation accuracy of the IBIS system is better than a millimeter and higher than the TM30 total station in the radar sight direction. Moreover, the IBIS system can achieve high resolution, high precision, and real-time deformation monitoring of large hydropower station slope for a long time.
