Abstract

For low-frequency multipole sources of various orders in a Pekeris waveguide, we have obtained and studied the dependences that determine the change in the structure and magnitude of interference maxima of the vector–scalar signal components with varying frequencies; waveguide, receiver, and source depths; and distances between them. Approximating expressions are found that, for different waveguide depths and source and receiver locations, are consistent with the exact decay laws of these field components in these zones. It is shown that the dependences of the fields of all multipoles based on the characteristics of the amplitude–phase structure are divided into two large groups.

干扰极大区中多极源低频场的空间矢量标量结构

摘要

对于Pekeris波导中各种阶次的低频多极源，我们已经获得并研究了确定随频率变化的矢量标量信号分量的干扰最大值的结构和大小变化的相关性。波导，接收器和源深度；以及它们之间的距离。发现近似表达式表明，对于不同的波导深度以及源和接收器位置，这些表达式与这些区域中这些场分量的精确衰减定律一致。结果表明，基于振幅相位结构的特性，所有多极场的相关性分为两大类。
