摘要
提出了一种改进阻抗边界条件的方法,并用格林函数法求解抛物方程的初始解;从而提高了抛物方程法的稳定性与精确度。最后基于抛物方程法分析了粗糙海面上的电波传播特性,得到的结果与Miller-Brown模型进行对比,结果吻合很好。
An improved impedance boundary method was presented and the initial field was calculated by Green function, which improved the stability and accurateness of the parabolic equation (PE). Eventually, the forecast of propagation over rough sea surface had been presented with parabolic equation (PE). The results from PE are compared with Miller-Brown model, good agreement is shown.
