C. Ichoku et al., EXPLORING THE UTILITY POTENTIAL OF SAR INTERFEROMETRIC COHERENCE IMAGES, International journal of remote sensing, 19(6), 1998, pp. 1147-1160
Using interferometric techniques, a complex coherence image was genera
ted from a pair of complex SAR data. Amplitude images were computed fr
om the SAR and coherence images and subjected to Principal Components
Analysis. The first channel of this analysis is an image of remarkable
clarity and detail, suitable for various applications. A good litholo
gic interpretation was realized from this single image channel alone.
