摘　　要：传统的地表沉降监测技术,如全球定位系统、精密水准测量和土工测量等,存在空间分辨率低、监测范围小和费用高的局限性。本文介绍了近几年迅速发展的监测地表沉降的合成孔径雷达差分干涉测量(D-InSAR)技术,主要对合成孔径雷达干涉测量(InSAR)技术的原理、D-InSAR技术的原理和处理流程做了详细的阐述,并对D-InSAR技术中的不足作了说明。Traditional surface subsidence monitoring technologies, for example, Global Positioning System, Precise Leveling and Geotechnical Measurements, have the limitation of low spatial resolution, small coverage and high cost. D-InSAR, which was developed in recent years, is introduced to monitor the surface subsidence in this paper. The principle of InSAR and process of D-InSAR were described in detail. Moreover, the deficiencies of D-InSAR were described too.
