Abstract
A new method to predict wave spectra is presented in this paper, which is based on X-band radar. Traditional methods to research ocean wave are usually based on the hypothesis that ocean wave is a stationary random process, which is proved to be not right. X-band radar is a remote sensing, ship borne equipment, which can measure wave information in real time conveniently. And the wave spectra measured by this equipment can represent non-stationary of ocean wave. In this paper wavelet decomposition and neural network is combined to predict wave spectra thus the trend how the ocean wave develop can be reflected. The experiment results show that this method is relatively credible.
