Hardware in the Loop Simulation for Low-Altitude UAV Link in the Complex Terrain

Abstract:

In order to investigate the influence of complex terrain on the quality of the unmanned aerial vehicle (UAV) communication link and simulate it accurately, the HITL simulation platform of the UAV-ground link, which was based on EXata software and Hardware-in-the-loop (HITL) module, was built. In the virtual terrain scenarios, the Free-space loss model and the Irregular Terrain Model (ITM) were used to modeling and conduct the semi-physical simulation experiments, respectively. Then, a new method of the HITL simulation for the wireless communication link was put forward, which achieved the real-time video stream interaction with the virtual networks. The simulation results showed the real-time changes of path loss in the complex terrain and the specific affection on the UAV-ground link communication quality from numerical and video transmission effect. The method enhanced the accuracy and rationality of the UAV-ground link simulation.
