分别利用数值模拟和实测资料对目前被认为分辨力较高的最大似然法（MLM）、扩展本征矢方法（EEV）、扩展最大滴方法（EMEP）以及贝叶斯方法（BDM）等四种海浪方向谱估计方法的可靠性进行了分析，从不同频率、不同噪声水平和不同方向集中度三个角度检验其再现性、稳定性和实用性，结果表明MLM、EEV和BDM大致给出相同的方向分布，其中BDM的再现性最好，但实用性逊于MLM和EEV，EMEP由于稳定性差，不适用于实测资料的分析． Using MLM, EEV, EMEP and BDM, respectively, which are currently considered as high resolution, respectively, using numerical simulations and field observations, The reliability of wave direction spectrum estimation method is analyzed. The reproducibility, stability and practicability of the method are verified from three different angles, different noise levels and different direction concentration. The results show that the MLM, EEV and BDM are approximately the same Directional distribution, of which BDM reproducibility of the best, but less practical than MLM and EEV, EMEP due to poor stability, not suitable for the analysis of measured data.
