| Abstract: | Ground Based Synthetic Aperture Radar （GBSAR）, as a new geoelimatic deformation monitoring equipment, synlhetic aperture technology and step frequency technology are used to get a high spatial resolution, hoth 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 hased on GBSAR are introduced. Further, by three experiments, namely dam-break simulaliml experimenh high structural wind-deviation deformation experiment and bridge load deformation experiment, it is verified that the system can be used in several defornmtion monitoring fields. |
