摘要

Abstract

Observation and analysis of ocean wave diffraction in near-shore and near-island region was performed with Synthetic Aperture Radar (SAR) data

using an optimized retrieval method named parameterized first-guess spectrum retrieval method. The results retrieved from ERS-SAR and ENVISAT-ASAR images showed that

in the region sheltered by land jut

the energy of long waves is reduced by 10%–20% and that the propagation direction of long waves is changed due to the effect of topography. In the shadow zone behind the island

ocean wave can propagate along the seashore instead of perpendicular to the coastline

as shown by SAR images.
