Monte Carlo simulation of backscattering signal from bubbles under water

摘要

This paper proposes a modified Monte Carlo method, namely the multilayer Monte Carlo simulation method, for simulating the return signal of light scattered by bubbles underwater. A curve representing the backscattering signal is obtained. The results predict a second backscattering peak in the total backscattering signal curve caused by the bubble layer underwater. The return time of the second peak is used to estimate the position of the bubble layer. Both the bubble layer's thickness and the distance between the emitter and the bubble layer will obviously affect the backscattering signal. A new theoretical method for detecting the bubble layer underwater and estimating its properties is presented.
