Determination of Ocean Wave Imaging Mechanisms by Airborne Synthetic Aperture Radars

Abstract

we analyse airborne Pi-SAR (Polarimetric-Interferometric SAR) X-bandimages of ocean waves around the Miyake Island at approximately 180 km south from Tokyo, Japan. Two images of a same scene were produced at approximately 40 min. interval from two directions at right angles. One image shows dominant range travelling waves, but the other image shows a di®erent wave pattern. This di®erence can be caused by the di®erent image modulations of RCS and velocity bunching.
