IBIS-L系统及其在大坝变形监测中的应用

The IBIS-L System and Its Application in Dam Deformation Monitoring

主要介绍了地基合成孔径雷达,阐述了干涉测量成像系统IBIS-L的结构和基本原理,将IBIS-L系统应用于国内外几个大坝的变形计算与分析,获得了较为准确的大坝位移量,认为IBIS-L系统可以应用于大坝的变形监测,同时认为大坝变形监测时受大气的影响较大,如何有效地进行大气影响改正和提高IBIS-L技术的变形监测精度是值得深入研究的课题。

This paper introduces The Ground - Based Synthetic Aperture Radar, expounds the structure and basic principle of IBIS - L interferometric imaging system. IBIS - L system was applied to the deformation calculation and analysis of several dam at home and abroad, won the more accurate displacement of the dam. We consider that IBIS - L system can be applied in deformation monitoring and that the dam is affected by the atmosphere is relatively serious. How to effectively correct the atmospheric effects and improve the precision of deformation monitoring of IBIS - L technology is worth studying further.
