一、问题的提出 海浪功率谱是描述海浪波面随机过程的基本特征参数,它既可研究海浪能量相对于频率的分布,又可研究海浪波面对外表现的统计规律。因此,准确求出海浪频谱具有重要的实用意义。目前常用的海浪频谱估计自相关法和周期留法,它们都引进一些假设及某种权函数的主观意志。最大熵法(MEM)是资料自适应谱估计法,它的窗函数是不固定的,是自身适应一个频率又一个频率,在一个频率上估计谱值很少受其它频率的方差 First, the problem raised Wave power spectrum is to describe the basic characteristics of wave surface stochastic process parameters, which can study the wave energy relative to the frequency distribution, but also the study of the wave surface of the statistical performance of the law. Therefore, it is of important practical significance to accurately find the spectrum of the waves. At present, the commonly used wave spectrum estimation autocorrelation method and periodic stay method, they all introduce some hypotheses and some kind of weight function subjective will. The maximum entropy method (MEM) is data adaptive spectral estimation method, whose window function is not fixed, itself adapts to one frequency and another frequency, and the estimated spectrum value on one frequency is less affected by the variance of other frequencies
