【摘要】 以射线声学理论为基础,推导出典型海洋环境下各类多途声线的海底混响平均强度计算式,在数值计算的基础上,分析比较各类多途声线海底混响的相对大小以及它们对总混响的贡献,以确定用射线线声学方法计算海底混响时,最有效的多途声线数。
【Abstract】 Based on Ray theory, we first induce the formula, which is used to culculate the average intensity ot the benthal reverberation from different multi-path sound-rays. And on the basis of numeric calculations, we compare the relative intensities of the benthal reverberations of different sound-rays and analyze their different contributions to the total reverberation. Therefore we can confirm the effective number of sound-rays needed to calculate the benthal reverberation by Ray Theory.
