粗糙海面对电波传播的影响研究
Research on Influence of Rough Sea Surface on Radio Wave Propagation
摘要
Abstract
The evaporation duct can partly trap electromagnetic waves,change propagation characteristics of radio wave,and eventually resulting in microwave propagation over-the-horizon above the sea,however,the roughness of the sea surface can weaken this effect.This paper considers the reflection factor that includes the shadow effect on the rough sea surface,then use PE model to simulate propagation loss,which is bigger than that simulated by Miller-Brown model.It shows that when wave length is shorter or near to the wave height,the shadowing effect on the sea surface cannot be neglected for the radio wave propagation.关键词
