Abstract :
A new inverse estimation method based on a Bayesian theorem is proposed for estimating directional wave spectra from SAR image. Numerical simulation was used to examine the validity and accuracy of the proposed method. The benchmark directional wave spectra and the estimated directional wave spectra were compared, and they show good agreement.
