摘要
基于一维带限Weierstrass分形函数模拟了几种海面形态,讨论了影响海面形态的分形函数的参数,并采用基尔霍夫近似方法,对模拟海面的电磁散射系数进行了计算仿真,并分析了海面的粗糙度对散射系数的影响,对电波在近海面的传播研究及应用有一定意义。
1-D Weierstrass fractal function was used to simulate several kinds of sea-surface, the fractal function parameter affecting the sea-surface was discussed. Aimed at the fractal surface, the relation of the scattering coefficient was computed by using Kirchhoff approximation. The effect of sea roughness on scattering coefficient was also analyzed. The result is of value to research and application on where the electric-wave propagated near the surface.
