Ocean wave detection by SAR

DOI: 10.1016/s0964-2749(97)80028-5


Summary Research and development of an Australian real-time satellite ocean wave spectra delivery scheme has been under way since 1991. This scheme, known as the Waves from Space project, makes use of satellite-borne Synthetic Aperture Radar (SAR) ocean wave imagery to process and produce 2D wave field spectra. This is then blended with altimeter wave height data to make wave predictions. This paper is concerned with the verification of the ocean wave spectra produced by the scheme. The directional spectra is compared with the measurements made from an offshore platform in Bass Strait and from wave buoys on the Northwest shelf. The agreement is satisfactory and shows the potential of the scheme to provide directional wave data all over the Australian region.
