摘要
GBSAR(Ground Based SAR)技术可实现静态动态结合的高精度高分辨率的形变监测。介绍了GBSAR技术的工作原理,并分析了该技术的精度影响因素。利用该技术对天津新海河大桥进行静态加载试验,结果表明GBSAR技术可测定桥梁的高精度挠度变化且可进行频谱分析。
GBSAR （Ground Based SAR） technology can achieve monitoring with the combination of static and dynamic modes. The on its work principles. The technology is used to the static loading high-precision high-resolution deformation facts affecting accuracy are analyzed based test of Haihe Bridge in Tianjing, and the results show that the bridge deflection change can be measured and spectrum analysis is also available.
