Based on the aviation channel characteristics, analysis was made to the background and applicable conditions of Egli, Okumura-Hata, and Longley-Rice models.A method for modeling the aviation wireless channel by using Longley-Rice model was proposed, and the simulation algorithm of the Longley-Rice model was deduced out.Simulation was made to analyze the attenuation of the model under different frequencies, different types of climate, and different terrains.Experimental data verify the accuracy and effectiveness of the model, which can provide a reference for aviation communication engineering modeling.
