摘　　要：根据电波传播的角谱理论原理,考虑两种极化波在导体、阻抗和粗糙边界层面上具有不同的反射系数,在初始场和分步傅里叶变换求解的过程中加入反射系数影响,从而得到可一致计算水平或垂直极化波传播特性的新算法.通过仿真计算电波在蒸发波导、粗糙海面情况下的传播损耗,并与APM(Advanced Propagation Model)的预测结果进行比较,验证了该算法的有效性.According to the principle of the theory of angular spectrum of electromagnetic wave propagation,considering two kinds of polarized wave have different reflection coefficients on the conductor,impedance and rough surface boundary layer,adding the effect of reflection coefficients to the solving process of the initial field and the Split-step Fourier Transform solution,so the new algorithm which can be used to consistently calculate the propagation characteristics of horizontal or vertical polarization wave is obtained.The propagation loss is computed by this new algorithm in evaporation duct and rough sea surface condition.The performance of the new algorithm is then demonstrated with the result of other model.
