Multidimensional Data Tensor-Based Modeling of GNSS-Based InSAR for Hourly 3-D Deformation Retrieval (opens in new tab)

Global Navigation Satellite Systems-based interferometric synthetic aperture radar (GNSS-based-InSAR) can overcome the limitations of repeat-pass time by receiving signals from different navigation satellite combinations at different times, enabling hourly 3-D deformation monitoring. However, this monitoring mode requires joint processing of scene reflected signals from multiple satellites in multiple time periods, resulting in massive data volumes. Traditional InSAR signal models, which only...
