摘要/Abstract

摘要： 地基合成孔径雷达（GB-SAR）是一种新型的建筑变形监测技术，相较于传统的监测手段，该方法拥有高精度，覆盖面大等优点。基于FMCW技术的Fast-GBSAR系统采用调频连续波技术，相较于国内已有的基于步进连续波技术的类似系统，该系统处理速度提高30倍，并拥有更高的可靠性。Fast-GBSAR在国内已对多座大桥进行了公开测试，监测结果表明Fast-GBSAR测量精度能达到0.01 mm，在变形监测领域极具潜力。

关键词: 地基合成孔径雷达, 调频连续波, 桥梁变形监测

Abstract: Ground-based synthetic aperture radar (GB-SAR) is a new type of building deformation monitoring technologies. Compared with the traditional monitoring methods, this method features high precision and large area. Fast-GBSAR is designed based on the frequency modulated continuous wave (FMCW) technology. Compared with the similar system based on the stepping continuous wave technology in China, the processing speed of the system is increased by 30 times and the reliability is higher. Fast-GBSAR has carried on the public test to many bridges in the country, the monitoring result indicated that Fast-GBSAR measurement precision can achieve 0.01 mm. Fast-GBSAR has the great potential in the deformation monitoring domain.

Key words: ground-based synthetic aperture radar, frequency modulated continuous wave, bridge deformation monitoring
