Abstract :
A nonlinear retrieval model was used to invert wave image data containing sunglint to obtain the elevation power spectrum. The sunglint images were thresholded to obtain binary glint images, from which the glint autocorrelation was calculated in one direction. A relationship was determined connecting the glint and slope random variables, which was then inverted to obtain the slope autocorrelation, from which the elevation power spectrum was obtained by integration and Fourier transform
