| 摘 要： | 抛物方程已经被广泛地应用于电波传播预测模型，并成为解决电磁波传播问题的主要工具。针对目前大多数预测模型处理粗糙海面的不足，引进了一种能包含海面阴影效应的粗糙度修正因子，并由于电波在海面上传播主要受到蒸发波导和粗糙海面的影响，结合抛物方程和蒸发波导理论对海面上的电波传播进行了研究，利用PE模型计算了电波在蒸发波导中不同条件下的传播损耗，并分析了蒸发波导和粗糙海面对电波传播的影响。

| Abstract: | The parabolic equation method is widely used in the electromagnetic wave propagation model and thus becomes the main tool for solving the problem of electromagnetic wave propagation.For the influence of both evaporation duct and rough sea surface on wave propagation,a modified roughness coefficient is given,the PE model and the evaporation duct theory are employed to simulate and analyze the propagation loss under different conditions. |
