Abstract: There are some problems in the general method of digital spectrum analysis. In this paper,the principle and the measure of estimation of sea wave power spectrum by maximum entropy method are discussed in detail and the characteristics of MEM are shown. The example is calculated on computer DPS 8/49 and a new spectrum analytical technique for the time series data of sea wave is proposed.
