Enhanced surface deformation monitoring in open-pit mines via dynamic filtering and multiscale adaptive interpolation of D-InSAR/offset tracking fusion

International Journal of Digital Earth
D-InSAR is sensitive to noise in low-coherence areas, while offset tracking lacks accuracy, making both insufficient for complex mining monitoring. Robust methods for stable monitoring of highly dynamic, large-gradient deformation remain urgently needed.

Across-Track and Multi-Aperture InSAR for 3-D Glacier Velocity Estimation of the Siachen Glacier

Remote Sensing, 2023
Interferometric Synthetic Aperture Radar (InSAR) remote sensing generally lacks deformation sensitivity in the along-track direction. In this proposed approach, across-track observations from conventional InSAR, using both ascending and descending passes,
