摘　　要：地基合成孔径雷达(GB-SAR)技术是近十多年发展起来的地面主动微波遥感技术,可进行非接触、高精度、大范围、远距离的变形监测,在变形监测领域具有重要意义。本文首先介绍了GB-SAR干涉测量基础理论和研究现状,归纳了目前主要的GBSAR系统,详细列举了现有系统的关键参数;进而分析了GB-SAR技术在基础设施、滑坡、矿山、冰川运动及文物保护等变形监测领域应用的优势和不足,总结了地基雷达系统在实际应用中面临的挑战;最后从多维形变、大气改正等方面对其应用前景进行了展望。Ground-based synthetic aperture radar( GB-SAR) is a ground-based active microwave remote sensing technology developed in recent ten years. GB-SAR system can be used for non-contact,high precision,large-scale and long-distance deformation monitoring,which is of great significance in the field of deformation monitoring. Firstly,this paper introduces the basic theory and research status of GB-SAR. The main GB-SAR systems are summarized and the key parameters of the existing systems are listed in detail. Then we analyze the advantages and disadvantages of GB-SAR technology in the field of deformation monitoring such as infrastructure,landslides,mines,glacier movements and cultural relics protection and summarize the challenges faced by ground-based radar systems in practical applications. Finally,the application prospects are prospected from the aspects of deformation monitoring multi-dimension deformation and atmospheric correction.
