摘要 

总结和分析了地表形变D-InSAR监测的主要方法和当前所面临的主要问题。针对常规D-InSAR技术中大气相位和低相干区域相

位解缠,分别介绍了基于Delaunay三角网的不规则格网解缠方法、累积干涉纹图处理方法(Stacking Interferograms)、永久性

散射体(PS)技术以及角反射器干涉测量(CR-InSAR)方法,分析了各自的适用条件和优缺点。此外,对有限数据量条件下低相干

区域大气相位校正、相干目标识别等问题进行了重点讨论。立足于工程应用需要,分别对D-InSAR测量地表形变的参数选择、测量

结果的精度验证、D-InSAR测量值与形变的关系、大区域处理以及形变场时空演变等问题进行了分析和讨论。

Abstract

Differential SAR interferometry has proved to be of remarkable potential for large-scale deformation

monitoring. However, a full operational capability has not yet been achieved due to atmospheric disturbance and

phase decorrelation phenomena. This paper deals with the main techniques for the application of InSAR to surface

deformation monitoring. Such techniques as the conventional SAR interferometry, Stacking Interferograms, Permanent

Scatterers Inteferometry and Corner reflector InSAR are presented in this paper, with their advantages and

limitations analyzed separately. The method for differentiating the atmosphere disturbance phase from the

deformation phase and the algorithm for identifying coherent point and spatial phase unwrapping based on Dealaunay

triangle network are discussed. From the viewpoint of practical application, the accuracy, precision and

reliability of D-InSAR measurement are analyzed. The key problems in the spatial integration processing of

multiple SAR images and the phase regression in the temporal domain of large coverage deformation mapping are also

studied.
