摘要In this letter, two multi-baseline differential synthetic aperture radar (SAR) interferometry (DInSAR) techniques, high-coherent point (HCP) and interferometric point target analysis (IPTA), were applied to monitor the displacement of Lantau Highway as an example of a large-scale artificial linear feature (LALF), using 17 ENVISAT advanced synthetic aperture radar (ASAR) images. The phase ramp was exploited and removed, combining the merits of two different model coherence functions when sparse HCP candidates were encountered. Then, two velocity fields from the advanced DInSAR methods were compared and analysed. The results indicate that the improved HCP method could generate a smoother deformation trend than the IPTA approach at the expense of losing detail information.
