Simulation and Spectral Estimation of Sea Wave Based on Shaping Filter

摘要：

This paper deals with the method of simulating sea wave for decreasing its disturbance in the watercraft navigating. Firstly the ITTC twoparameter spectrum is selected as the power spectrum of sea wave to be simulated. Secondly the selected power spectrum is approximated by the rational spectrum and its coefficients are calculated by least squares method. Finally the shaping filter is concluded and the simulated sea wave is obtained by inputting white noise to the shaping filter. The spectrum analysis by Welch verities the simulated sea wave. Without loss of generality, this method is practical in engineering and important for the operating parameters of watercraft prediction and filtering, the forcast of sea wave and marine dynamic positioning.
