Lithology classification of igneous rocks using C-band and L-band dual-polarization SAR data
Open Geosciences, 2023 Distinguishing different kinds of igneous rocks is difficult because of their subtle differences. Synthetic aperture radar (SAR) is sensitive to rock surface morphology, which can help a lot in classification. Dual-pol SAR data have the advantages of low

Sentinel-1 Support in the GAMMA Software [PDF]
Procedia Computer Science, 2015 AbstractFirst results using the new Sentinel-1 SAR look very promising but the special interferometric wide-swath data acquired in the TOPS mode makes InSAR processing more challenging than for normal stripmap mode data. The steep azimuth spectra ramp in each burst results in very stringent co-registration requirements.
