| 中文摘要: |
| 基于理论和模型仿真对孤子内波存在下的水平纵向相关系数的变化进行了研究。理论上推导出浅海孤子内波存在情况下的声场水平纵向相关系数随时间的变化规律，并且运用二维抛物方程模型（Ram）验证理论推导结果。结果表明，孤子内波会导致水声纵向相关系数的变化，并且水平纵向相关系数的变化是由于简正波的干涉所导致。我们给出特定环境下的水平纵向相关系数随时间变化的结果，当环境中第一、二号简正波占主导地位时，水平纵向相关系数会呈现出周期变化的结果。 |
| 英文摘要: |
| The variation of horizontal longitudinal correlation coefficient in the presence of internal soliton waves is studied based on theory and model simulation. The variation law of horizontal longitudinal correlation coefficient with time in the presence of the internal wave is derived theoretically and the model of parabolic equation is used to verify the theoretical derivation. The result show that because of the interference of normal wave, the internal soliton wave will cause the change of horizontal longitudinal correlation coefficient. This paper we give the result of the variation of horizontal longitudinal correlation coefficient with time in a given environment, when the first and second normal waves are dominant in the horizontal waveguide, the horizontal longitudinal correlation coefficient will have periodic variation. |
