| 摘 要： | 为了使地基合成孔径雷达（ground-based synthetic aperture radar，GB-SAR）在地表微变形监测领域得到更广泛的应用，首先概述了GB-SAR的主要类型，并选择几种具有代表性的系统介绍了其工作原理及重要参数。然后以中国安全生产科学研究院自主研发的边坡合成孔径雷达型地基雷达为例，总结了常规差分干涉处理中的重要技术，利用相似模拟实验验证了GB-SAR的监测精度，并且展现了GB-SAR在露天矿山边坡监测、矿山排土场监测和山体滑坡应急救援监测方面的应用。最后提出了GB-SAR在变形监测中存在的一些问题以及后续发展中的建议。

| Abstract: | In order to promote the wider use of ground-based synthetic aperture radar (GB-SAR) in the field of surface micro-deformation monitoring, this paper summarizes the main types of GB-SAR and introduces the working principles and important parameters of some representative systems. By taking the S-SAR (slope-synthetic aperture radar) ground-based radar independently developed by the China Academy of Safety and Production Science as an example, the key processing techniques utilized by the GB-SAR are introduced. Experiments verify the accuracy of GB-SAR. It also shows the application of GB-SAR in open pit mine slope monitoring, mine dumping site and landslide emergency rescue. Finally, the problems and suggestions of GB-SAR in monitoring are proposed. |
