InSAR - surface deformation
Measures millimetre-scale ground surface displacement by comparing phase differences between repeat SAR passes; good for subsidence, earthquake deformation, and volcanic monitoring.
Interferometric phase encodes range change between passes. Requires precise orbit knowledge and temporal coherence between acquisitions. Wikipedia: Interferometric synthetic-aperture radar
