| 摘 要： | 提出了一种利用远区散射场提取粗糙面分形特征即Hausdorff维数的方法.首先研究了确定分数维的"无标度区法",然后讨论了分形函数的分形插值概念和方法,最后以此为基础提出了粗糙面分形特征的提取方法,该方法充分利用了分形函数模拟粗糙面时的特征,使特征的提取工作简单明了.

| Abstract: | A
method of getting the fractal characteristics of rough surfaces i.e. Hausdorff dimension
by scattering coefficient is presented. The concept of “scaling range” and the fractal interpolation are discussed. In this
method, the characteristics of fractal function is fully considered when it is used to
characterize the rough surfaces and the method makes the work getting the fractal
characteristics of rough surfaces simple and clear. |

| Keywords: | fractal function rough surface fractal interpolation Hausdorff dimension |
