关于海浪ARMA模型的研究

THE STUDY ON ARMA MODELS FOR SEA WAVES

本文研究了用ＡＲＭＡ模型描述海浪运动的数学模型。通过ＡＲＭＡ模型的参数估计，给出了描述海浪运动的ＡＲＭＡ模型，利用仿真数据进行了拟合检验。结果表明：本文提出的海浪ＡＲＭＡ模型是一种非常理想的数学模型，且适于在线递推运算，便于工程应用。

In this paper, the mathematic models for sea waves are expressed as the ARMA model. By means of parameters estimation for ARMA model, the ARMA models for sea waves are given, and veryfication is carried out with simulated data. It is shown that the ARMA models for sea waves presented in this paper are satisfactory models, and as they are recursion equations, they can be used easily in engineering.
