摘要: 星载合成孔径雷达干涉测量(InSAR)技术是近年来迅猛发展的一种空间对地观测技术,在InSAR基础上提出的多时相InSAR(MT-InSAR)方法,利用同一地区的多景SAR影像对时序稳定点(PS)进行精确分析,极大地降低了大气延迟等带来的测量误差,使得形变监测精度达到了厘米级到毫米级,可对城市基础设施进行大范围高精度的连续监测。本文通过对MT-InSAR技术发展的综述,总结了目前MT-InSAR技术在基础设施健康监测方面的关键问题和应用领域,并对未来MT-InSAR在城市应用方面的发展提出了展望。

Abstract: Synthetic aperture radar interferometry (InSAR) is a well developed earth observation technology in the last two decades. It can measure minute movements and digital elevation model with high accuracy over large areas by inteferometric processing of two SAR images. In particular, multi-temporal InSAR (MT-InSAR) can achieve centimetric to millimetric deformation monitoring by properly removing atmospheric delay using multiple SAR images. This paper gives a review of current cutting-edge MT-InSAR algorithms. The focus is on the key technologies of MT-InSAR and the primary application fields for urban infrastructural health monitoring. Finally, we give some suggestions for the future development of this technology.

Key words: InSAR, MT-InSAR, PS, urban infrastructure, deformation monitoring
