Quantitatively Estimating of InSAR Decorrelation Based on Landsat-Derived NDVI

Remote Sensing, 2021
As a by-product of Interferometric Synthetic Aperture Radar (SAR, InSAR) technique, interferometric coherence is a measure of the decorrelation noise for InSAR observation, where the lower the coherence value, the more serious the decorrelation noise. In
