Abstract :
A new technique has been developed to measure ocean surface slopes by polarimetric SAR. This technique has the potential of estimating surface slope in the along-track direction at an accuracy of a fraction of a degree. Experimental results using NASA/JPL AIRSAR P-, L-, C-band data from the Gulf Stream´90 Experiment showed a sudden slope change at a converging current front. The effect of velocity bunching on this measurement technique is also investigated
