Synthetic aperture radar imaging of ocean waves during the Marineland experimentWave contrast measurements are used to analyze X and L-band simultaneously obtained synthetic aperture radar (SAR) data of ocean gravity waves collected during the Marineland Experiment (1975). The results of the wave contrast measurements show that the ocean waves imaged by a SAR are more discernible using an X-band frequency than an L-band frequency and when the ocean waves are traveling in the range direction. It is determined that ocean waves can be detected by both X and L-band SAR, provided that the radar surface resolution is a small compared to the ocean wavelength. In addition, wave detection using L-band SAR can be improved by adjusting the focal distance and rotation of the cylindrical telescope in the SAR optical processor to account for wave motion. This adjustment is determined to be proportional to a value that is near the wave phase velocity.
