This paper presents the path loss theoretical and experimental investigation for rural area. Accordance between the International Telecommunication Union Recommendations and the diffraction theory is demonstrated. The concept of the Earth’s equivalent radius for the linear model of the troposphere is summarized to the exponential model. It is shown that the radio waves propagation conditions can be predicted using the backscattered radar signal from the terrain surface.
