摘要
在水深1.0米,具有平坦海底的区域作了时域分离简正波的模拟实验,得到了1、2、3号简正波。由分离出的简正波相对幅度计算了海底反射损失因子Q。所得实验数据与理论计算结果符合甚好。计算所得Q值与由底质采样所得Q值基本一致。
Time-domain mode seperation simulation was made in a region with a smooth bottom and a water depth of 1.0 m and the first three modes were obtained. The bottom reflection loss factor Q, which is defined in the formula- In |V(x)|=Qx, where V is the reflection coefficient and x the grazing angle, was calculated from the relative amplitudes of the modes. The data obtained in the experiment are generally in good agreement with theoretical calculations, and the value of Q thus obtained is consistent with its value obtained by the method based on bottom sediment sampling.
