Research on detection of internal wave area based on power spectrum in SAR image

Synthetic Aperture Radar (SAR) is important method in ocean remote observation, most ocean surface in SAR image have specific texture character. Ocean Wave, internal wave, ocean eddy, island have different character in SAR image, so is power spectrum. We get power spectrum character of different texture character in SAR image by Fourier transform, and conclude the specific power spectrum character of internal wave. As a result, the method can be applied in detecting internal wave area.
