| 摘 要： | 设计了一个特殊且相对规则的散射界面模型,并利用声波动方程高阶有限差分的方法对其进行正演。通过不断改变模型中散射体的横向尺度来控制多次散射波场的强度和特征,然后结合高阶谱统计分析的方法对所得的多次散射波进行分析,进而可以得到多次散射波频率随散射体横向尺度而变化的一些规律。

| Abstract: | We have designed a special but relatively regular model with for multiply scatter wave,and it has been forwarded through the high order finite difference scheme of the acoustic wave equation.The force and character of the multiply scatter wave can be controlled by changing the horizontal scale of the model,and the data be analyzed through high order spectrum-statistic method,and the result reveal some of the rules about the frequencies of the multiply scatter waves which are produced under different scales. |
