Abstract:

Ocean wave is an important ocean environment parameter. It has significant meaning for harbor
construction, navigation and exploitation of oilfield. Synthetic Aperture Radar (SAR ) is a primary
instrument to measure ocean wave in large-scale area. SAR estimates wavelength and direction of
propagation quite well, But it is very difficult to provide quantificationally amplitude of ocean wave as well
as relation between SAR image intensity and ocean surface. Besides, it is complex to obtain ocean wave
spectrum from SAR image spectrum. Along-Track Interferometric Synthetic Aperture Radar (ATI-SAR )
is an act ive coheren t imaging system , w hich has two an tennas separated along the platform flight
direction. The phrase image of ATI-SAR less depend on real aperture radar modulat ion transfer function
than synthetic aperture radar. Therefore, ATI-SAR is more suitable to measure ocean wave. This paper
introduces the imaging mechanism of ocean wave by Along-Track Interferometric Synthetic Aperture
Radar, It establish firm foundation to inverse ocean wave directional spectrum further. Finally, we discuss
some issues in present study and research orientation in the future.

Key words: Interferometric synthetic aperture radar, Remote sensing of ocean wave, Imaging mechanism , Ocean wave directional spectrum
