摘要/Abstract

摘要： 地基合成孔径雷达系统（GBSAR）作为一种新型的对地形变监测设备，通过合成孔径技术和步进频率技术实现雷达影像方位向和距离向的高空间分辨率，获得亚毫米级微变形监测精度。介绍了基于GBSAR地基快速雷达微变形监测系统的原理和应用模式，然后通过大坝溃坝模拟实验、高建筑物风偏变形和桥梁负载微变形实验分析验证了该系统可有效应用于多个变形监测领域。

Abstract:

Ground Based Synthetic Aperture Radar (GBSAR), as a new geoclimatic deformation monitoring equipment, synthetic aperture technology and step frequency technology are used to get a high spatial resolution, both on cross-range and range of the radar image, and get sub-millimeter level accuracy for the micro-deformation monitoring. The principle and application mode of micro-deformation monitoring system based on GBSAR are introduced. Further, by three experiments, namely dam-break simulation experiment, high structural wind-deviation deformation experiment and bridge load deformation experiment, it is verified that the system can be used in several deformation monitoring fields.

Key words: GBSAR, deformation monitoring, dam deformation monitoring, bridge deformation monitoring
