IBIS-L系统与TM30全站仪在边坡变形监测中的对比分析

使用IBIS-L系统对大型水电站边坡长时间的监测数据进行分析和处理,并与TM30全站仪进行变形监测精度对比。试验表明,IBIS系统可得到在雷达视线方向优于mm级精度的形变结果,优于TM30全站仪,可以实现高分辨率、高精度、实时的大型水电站边坡长时间变形监测。

Comparative Analysis of IBIS-L System and TM30 Total Station in Monitoring Slope Deformation

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.
