当孤立子内波的波阵面与声传播路径所成角度较大时,简正波耦合是导致声信号起伏的主要因素。研究了浅海中孤立子内波引起的声能量起伏规律,给出声场起伏的耦合简正波表达式,并使用抛物方程模型进行仿真。数值分析表明,接收点声强随时间变化呈准周期性。在频谱图中能够得到声强起伏的主导频率,主导频率与孤立子内波沿声传播路径的移动速度成正比,与无扰动波导中简正波在距离上的干涉周期(对应于射线理论中临界声线的跨度)成反比,与孤立子内波的形状无关。此外,对声强频谱的垂直结构进行了分析,该结构与对声场起伏起主要作用简正波的本征函数相关。

复杂海域通常存在环境参数的水平变化,这会导致声波在传播过程中发生水平折射,呈现出三维效应.利用绝热简正波-抛物方程理论进行三维声场建模,在垂直方向上使用标准简正波模型KRa.EN求解本征值和本征函数,水平方向上使用宽角抛物方程模型Ra.求解简正波幅度.该模型物理意义清晰,计算效率高,但由于忽略了各号简正波之间的耦合,只适用于环境参数水平变化缓慢的问题.使用该模型分析了内波环境和大陆架楔形波导中的声波水平折射现象,结果表明,声波的水平折射将水平平面分为不同区域,每个区域内的声场结构明显不同.此外,声强在水平平面内的分布与声源频率和简正波号数有关,这种依赖关系是导致声信号频谱变化、波形畸变以及声场时空扰动的主要原因.

0引言海洋中声传播受海底特性的严重影响,海底声学参数反演在水声学中受到了广泛关注。大部分反演方法基于主动机制,通过观测声源发出的信号来获取海底参数。被动反演方法通常使用环境噪声代替指定声信号,其中一个关键问题是格林函数提取。海洋波导中两点间的格林函数可以通过两个水听器所记录噪声求得的互相关函数来近似。如果声源发出的脉冲信号在远处多个点被接收,对接收信号在时间上进行反转并重新发射出去,声波将会在初始声源处聚焦,该过程被称作时
