| 摘 要： | 利用蒙特卡罗方法对气泡幕后向散射接收信号及其各次散射分量进行了系统仿真,并详细讨论了不同接收视场和气泡幕密度下的多次散射效应.结果表明:高次散射信号在气泡幕回波信号中占有重要的成分.不能以单散射来近似计算;随着接收视场和气泡幕密度的增加,高次散射分量在接收信号中的比重增加,有利于气泡幕后向散射信号的探测.

| Abstract: | Monte Carlo simulation is used to obtain the light backscattering signal and the multiple scattering signals of bubble film in water.Based on this the effect of multiple scattering in different field of views and different bubble densities is discussed in detail.It is turned out that: the multiple scattering signal is very important in the bubble film scattering signal and the first scattering signal can't be instead of the bubble scattering signal;as the increase of receiver field of view and the bubble de... |
