摘要
讨论了海浪波动基本规律,分析了海浪波动对水下接收点电磁场相位的影响。理论推导表明,这种影响取决于海浪的波高和水下接收点的深度。海浪波动会造成电场相位波动。在近似正态分布的海浪作用下,水下电磁场相移呈现出对数正态分布的规律,水下接收点的平均深度主要影响相移的均值,浪高的标准差主要影响相移的标准差。海浪对相移特性的影响与电磁场频率有关。
The effect of sea wave on underwater electromagnetic field phaseshift is discussed. It is shown that the height of wave and the depth of underwater point determine such effect. Under the action of sea waves with approximate normal distribution, the phaseshift of electromagnetic field presents logarithmic Gauss distribution. Waves can affect phaseshift magnitude. Effect of sea wave on phaseshift characteristics is related to electromagnetic field frequency.
