Abstract: The present invention develops a theoretical model relates to the nonlinear acoustic scattering of difference frequency components capable of being applied to an actual marine sedimentary layer and to laboratorial conditions. Nonlinear acoustic variables of a bubble containing sedimentary layer is estimated under the laboratorial conditions by using the developed model, and the amount of air contained in the sedimentary layer based on the estimated nonlinear acoustic variables. The similarity of the estimated values is confirmed by comparing the estimated amount of air and the amount of air estimated by using a sonic change generated inside the sedimentary layer. Additionally, the impossibility of estimating the amount of air is confirmed with the sonic change when the amount of air contained in the sedimentary layer is minute. These mean that a nonlinear acoustic exploration method can be usefully used for quantitatively estimating the amount of air contained in the sedimentary layer. Nonlinear acoustic variables of a submarine sand sedimentary layer containing a minute amount of bubbles of an actual shallow sea are estimated by utilizing those advantages of the nonlinear acoustic exploration method, and the amount of air contained inside the sedimentary layer is estimated. The estimated nonlinear acoustic variable (ε) is 576. The value is very large in comparison with a nonlinear acoustic variable of a normal sand sedimentary layer containing no bubbles. These mean that bubbles are contained in the sedimentary layer, and the estimated amount of air contained in the sedimentary layer (β) is 1.84×10-6.
Abstract translation: 本发明开发了一种涉及能够应用于实际海洋沉积层和实验条件的差频分量的非线性声散射的理论模型。 基于估计的非线性声学变量，通过使用开发的模型和沉积层中所含的空气量，在实验条件下估计含有沉积层的气泡的非线性声学变量。 通过比较估计的空气量和通过使用在沉积层内产生的声音变化估计的空气量来确认估计值的相似性。 此外，当沉积层中所含的空气量微小时，可以用声音变化来证实不可能估计空气量。 这意味着非线性声学探测方法可以有效地用于定量估计沉积层中所含的空气量。 通过利用非线性声学探测方法的优点，估计了含有实际浅海中微量气泡的潜艇砂沉积层的非线性声学变量，估计了沉积层内部的空气量。 估计的非线性声学变量（ε）为576.与不含气泡的正常砂沉积层的非线性声学变量相比，该值非常大。 这意味着沉积层中含有气泡，沉积层（β）中所含的空气的估计量为1.84×10-6。
