【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, the improved third-order Stokes wave is proposed as the component wave in order to broaden the research approach to establish the nonlinear wave spectrum model in deep water. A nonlinear ocean wave model based on the modified autoregressive model AR-spectral estimation method is presented. The time series of wave surface height are retrieved based on simulated spectrum and phase spectrum (hereinafter referred to as wave wave). The superiority of the new spectrum is verified by the spectral comparison method of the time-history inversion method. It provides the technical support for the accurate evaluation of wave spectrum, and it is of great significance to enhance the future control of the sea battlefield.
