Abstract

A theory of internal wave synthetic aperture radar (SAR) imaging has been improved by applying Korteweg-de Vries (KdV) equation, Bragg back scatter model, and replacing surface wave action equation with high frequency ocean wave spectrum balance equation. An analytical expression for an ocean internal wave SAR image will be obtained. Based on the new theory, the effects of wind on internal waves SAR images are studied with theoretical and scale analysis. The results indicate that the effects of wind are comparable with the hydrodynamic parameters, and the signature of internal waves can be imaged on the SAR only when oceanic state is low. The results agree well with some observations.
