Abstract  

A new method to measure ocean wave slope spectra using fully polarimetric Synthetic Aperture Radar (POLSAR) data was developed without the need for a complex hydrodynamic modulation transform function. There is no explicit use of a hydrodynamic modulation transfer function. The results estimated from NASA/JPL AIRSAR C-band polarimetric SAR data show that the ocean wavelength, wave direction and significant wave height are in agreement with buoy measurements. In the velocity bunching model, a nonlinear mapping relationship between dual-polarization SAR image spectra and ocean wave spectra is derived.
