| 摘要: |
| 为了拓宽建立深水非线性海浪频谱模型的研究途径, 基于三阶斯托克斯波理论, 提出了以改进的三阶斯托克斯波为组成波, 以修正的自回归模型(AR)谱估计方法得到的估计谱(简称新谱)为靶谱的非线性海浪模型。通过基于模拟频谱和相位谱反演海浪波面高度时间序列(以下简称海浪时历反演方法)的谱比较方法验证了新谱的优越性, 为从根本上解决精确评估海浪谱提供了技术支撑, 对于增强未来掌控海战场具有重要意义。 |

| Abstract: |
| Based on the third-order Stokes wave theory, a nonlinear wave model is proposed, which uses a modified third-order Stokes wave as the component wave and a modified AR model spectrum estimation method as the target spectrum. It is a new way to establish the spectrum model of a deep-water nonlinear wave. The spectral comparison method, based on the time series of ocean wave height established from the simulated spectrum and phase spectrum, is used to verify the superiority of the new spectrum, which provides technical support for the fundamental estimation of the ocean wave spectrum and can help control the sea battlefield in the future. |
