摘要
采用分步傅里叶算法求解抛物方程,重点分析阻抗边界条件的数值处理方法,构成分段线性地形,通过改变电磁和环境参数进行仿真计算,研究天线参数与地形环境对电波传播特性的影响。
Based on split-step Fourier algorithm, the parabolic equation can get a solution . Mixed Fourier transform algorithm for rough surface and impedance boundary is also studied. Combining the data with terrain PE, characteristics of radio propagation in complex terrain can be predicted. By changing the antenna parameters and environment conditions, the mutual effects between radio wave and complex terrain are simulated and analyzed and the results agree with the propagation theory and mechanism.
