Abstract :
Fully-polarimetric SAR images from two scenes from the west coast are analyzed to study the modulation of polarimetric coherence by ocean features. Co-polarized and circularly polarized coherences are calculated for ocean surface waves, a weather front, a coastal plume and a ship wake. The study concludes that changes in short scale surface roughness did not modulate the co-polarized coherence. But changes in the dielectric constant did affect this coherence.
