Study of Characteristic Prediction of Radio Wave Propagation Loss on Complex Irregular Terrain of Wide-range Distance

摘要：

　　Common radio wave propagation models are very theoretical and restrict.They are not suitable to apply to general propagation environments.And the calculation process is too complicated to apply in engineering conveniently.Summary of the previous researches,this paper considered the theory of radio wave propagation models about distance from the hundreds of meters to hundreds of kilometers.One prediction method for characteristic of radio wave propagation loss on complex irregular terrain is proposed.This paper used real topographic information of the SRTM-DEM(Shuttle Radar Topography Mission-Digital Elevation Model) data and extracted the path profile information to analyze the point-to-point communication propagation path loss.The simulation results prove that the prediction method is valid within the frequency range from 400MHz to 20GHz.
