摘要
变形监测是星载InSAR技术应用最为成熟的领域之一。本文首先介绍了InSAR变形监测的基本原理和卫星数据来源;然后对InSAR变形监测方法进行了系统性的分类,分析了D-InSAR、PSInSAR、SBAS-InSAR、DS-InSAR和MAI等方法的技术特点和适用范围;进而从应用的角度分析了InSAR技术在城市、矿山、地震、火山、基础设施、冰川、冻土和滑坡等领域的研究现状和不足之处;最后总结出InSAR变形监测在多维形变和低相干区测量、大气和轨道误差去除和精度评定等方面的前沿问题。
Deformation monitoring is one of the most mature applications of space-borne InSAR technique.Firstly,we introduce the basic principle of InSAR in the monitoring of deformation and the current SAR satellites.The deformation monitoring methods of InSAR are then classified into the groups of D-InSAR,PSInSAR,SBAS-InSAR,DS-InSAR and MAI,which are analyzed in the aspects of technical features and application scopes.Subsequently,we analyze the research progress and deficiencies of InSAR in the investigation of urban,mining area,earthquake,volcano,infrastructure,glacier,permafrost and landslide.Finally,some advanced academic problems such as deformation monitoring in multi-demension and low coherence area,atmospheric and orbital errors mitigation,and accuracy assessment are concluded.
