摘要
作为计算电磁波传播衰减的常用方法之一,射线追踪法可以有效的对波场进行近似计算。文中描述了射线追踪法,利用此方法对蒸发波导条件下的传播损耗进行数值计算,并与AREPS软件的计算结果进行比较,两者在视距范围内比较吻合。
As one of the commonly used methods, the ray tracing can compute the wave field efficiently. In this paper, the ray tracing is introduced firstly, and then the propagation loss is computed to make use of this method in the condition of evaporation duct. And the result agrees well with that of AREPS within a certain range.
