摘要/Abstract

摘要： 分形表面的远区场分析最初是在频域进行,该文通过推导出不同频率下分形目标散射系数的相同形式,进一步得到散射系数的时域解,改变控制分形函数的参量来观察和分析各种不同情况下的粗糙面在时域中的远区散射场.

Abstract: In this paper, fractal function is used to model the rough surface for investigating the interaction of incident plane wave and rough surface in frequency and time domain. The different characteristics for different parameters of the fractal function in time domain are presented.

Key words: fractal structure, rough surface, Kirchhoff approximation algorithm, EM scattering in time domain
