摘要
采用Weierstrass分形函数模拟实际粗糙表面,从简谐光波满足的亥姆荷兹方程出发,利用基尔霍夫近似推导出一维Weierstrass分形粗糙表面的相干散射场,数值计算并分析了相干雷达散射截面的角分布特性。
Weirerstrass Fractal function was introduced to simulate a real rough surface. Based on Hehnholtz equation and Kirchhoff approximation, the coherent scattering field on 1-D Weirerstrass fractal surface was deduced as well as the characteristics of angular distribution of the coherent radar scattering cross section was numerically calculated and analyzed.
