Abstract
Ocean spectral peaks extracted from synthetic aperture radar (SAR) ima gery exhibit a wavenumber rotation and shift relative to the true peak s due to attenuation of the high azimuth wavenumbers. We develop an ap proximate analytical model allowing a correction to the rotation and s hift of SAR spectral peaks. This model maybe useful for spectral peak correction when R/V less than or equal to 60 s whereas; for RIV > 60 s , a portion of the wave images are strongly nonlinear for which this m odel is not valid.
