| 摘 要： | 海底是海洋的反射边界,它有若干与海面相似的特性。但是,由于海底的不同成分和多层的结构,其作用更加复杂,显著地影响声波的传播。声波在海底反射时造成能量损失,同时也造成影区的声场,能量损失会限制其传播距离。研究了强割裂海底区有效反射系数的频率特性,并运用Matlab软件进行了实验仿真。

| Abstract: | Seabed which is the reflecting boundary of sea is similar in characteristics to offing.However the reflecting is more complex which has an impact on the sound wave propagation owing to the different components and multilayer structure of seabed.The lose of energy will reduce the propagation distance.In this paper,frequency characteristics of effective reflectance on dissevered seabed has been studied and simulated in validity using Matlab. |

| Keywords: | dissevered seabed effective reflectance frequency characteristics |
