摘　　要：蒸发波导是海洋大气中一种常见的自然现象,受其影响,电磁波的传播轨迹会显著改变。利用近几年采集的我国海区的实测修正折射率剖面和气象水文数据,得出了A模型在我国海区的适用性结论。所得结果对波导模型的修正和蒸发波导条件下雷达最大探测距离的预测具有一定的指导意义。Owing to the evaporation duct, the path of electromagnetic waves is changed. The applicability of Model A in Chinese sea areas has been studied by using the modified refractivity profiles and hydrometeorological data measured in the experiments during recent years. The conclusions offer some help for improving the evaporation duct model and forecasting the maximum radar detection range in the condition of evaporation duct.
