Some results are presented on the application of new spectral estimation techniques using AR and ARMA models, also known as Maximum Entropy- Methods, to wind wave spectral analysis. The results are compared with those obtained with conventional FFT methods. The application of some mathematical methods for model order selection is included. The relation between the optimum order and different spectral parameters is investigated.
