Path Analysis of Diffraction Model in Mountainous Environment

Abstract

This paper analyzes the wireless transmission path model in mountainous environments. Diffraction propagation is the main method of electromagnetic wave propagation in mountainous environment. This paper first analyzes the mountain diffraction loss model based on fresnel integral and discusses the expansion formula of fresnel integral, and applies the range to single peak diffraction formula and double diffraction. Last discussed the relationship between the frequency, distance and height of radio wave propagation when the receiver sensitivity is 150dB, and finally the establishment of the diffraction model, which improves the process of radio wave prediction effectiveness.
