中文摘要：

简述了地基干涉雷达系统用于动态形变监测的基本原理,提出了针对地基干涉雷达监测数据特点的桥身局部相对形变分析方法。结合桥梁静载试验形变过程进行分析,说明了该方法在实际桥梁结构安全监测中的可行性。

英文摘要：

This paper gives a brief introduction to the basic principles of ground-based inter- ferometric radar system for dynamic deformation monitoring, and then presents a local rela- tive deformation analysis method for bridge structures considering the characteristics of radar data. Case studies of actual bridge monitoring tests illustrate the feasibility of this method.
