Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Simultaneous analyses of complementary GNSS and InSAR measurements may lead to breakthroughs in our understanding of crustal deformation. We present an algorithm that combines InSAR with GNSS measurements, in which the GNSS data can be used either as original station velocities or as an interpolated and smoothed velocity field, to estimate ...

Using Phase Unwrapping Methods to Apply D-InSAR in Mining Areas
Canadian Journal of Remote Sensing, 2019 Phase unwrapping is one of the key processing steps of D-InSAR (Differential Interferometric Synthetic Aperture Radar), and its accuracy has a great impact on the accuracy of interferometric deformation results. Therefore, it is necessary to choose the proper phase unwrapping method for mining deformation monitoring with different coherence by the ...
