Lithology classification of igneous rocks using C-band and L-band dual-polarization SAR data

open access: yesOpen 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
