Propagation Modeling for UAV Air-to-Ground Channel Over the Simple Mountain Terrain
The use of unmanned aircraft systems (UAS) for the fifth generation (5G) and beyond 5G (B5G) mobile communications has aroused great attention in decade years. Regardless of the control and non-payload communication and payload communication, the unmanned aerial vehicle (UAV) air-to-ground (AG) channel essentially determine the link performance. In addition, the AG channel presents distinct characteristics in different scenarios. In the mountain scenario, the UAV is generally used to provide communication coverage and collect the data from the ground sensor node (SN). In this paper, an analytical multipath propagation model for UAV AG channel in such a scenario is presented. The path length of the reflections from the mountain is calculated through the geometrical relationship. Moreover, the result turns out that the survival time of the single-bound reflection from the mountain is larger than that of the double-bound reflection. In addition, the propagation mechanism is validated by ray-tracing simulations and the proposed path loss model is more capable of describing the channel behavior than the mostly used two-ray model in AG channels.
