摘要

对空中运动声源激发水下声场的空间分布进行建模研究,为水下对空中目标探测提供重要的技术基础。针对于空中运动声源激发声场的空间分布模型建立的问题,本文从波动理论出发,通过对波动方程进行Fourier-Bessel变换达到降维的目的,得到只与深度有关的方程。利用有效深度法得到所需的特征值,最终利用边界条件得到声场的积分表达式,对其进行波数积分得到空中运动声源激发声场的空间分布模型。
Research on establishing spatial distribution model of sound filed stimulated by air-born moving source can provide important technique foundation for detecting air target from water. This paper based on wave theory, processes Fourier-Bessel transform on both side of wave equation to drop dimensions, then acquires eigen value by effective depth and integration expression by boundary condition, finally by wave number integration distribution of sound field in the air and water of two media and Pekeris waveguide are obtained.
