Modeling of incident waves near the ship’s hull (application of autoregressive approach in problems of simulation of rough seas)

Abstract

This chapter introduces the basics of the ARMA (Autoregressive Moving Average) model of short-crested wind waves. The model consists of an autoregressive component for temporal dependence and evolution and a two-dimensional moving average component for spatial dependence and propagation. A brief description of the validation of the model is given with special emphasis on the analysis of the dispersion relationship.
