Shallow reverberation is mainly caused by the bottom scattering.

浅海混响主要是海底散射引起的。

In the littoral environment, the bottom scattering is one of the most important factors for limiting the performance of active sonar.

在浅海环境中，海底散射是影响主动声纳性能的最主要因素之一。

The method and results would be useful for analysing angular and frequency dependence of the bottom (or surface) scattering at low grazing angles.

本方法和结果将有助于分析小掠角海底(面)散射的角度、频率依赖关系。
