基于小波变换的海浪方向谱估计方法研究

摘要

The applicability of the estimation of the directional spectrum based on wavelet transform is discussed using the data generated from the numerical simulations. The analysis focusing on the influences of measured array types, wave incident direction, directional concentration and sampling lengths on the directional spectrum based on wavelet transform is carried out, which shows that the wavelet direction spectrum is more widely applicable.%利用数值模拟方法分析了基于小波变换的方向谱估计分析方法的适用性，测波阵列类型、波浪入射方向、方向集中度以及采用长度对小波方向谱估计分析方法分析结果的影响。结果表明：小波方向谱的方法适用条件较广泛，实用性更强。
