Modeling and Simulation of HF Aeronautical Mobile Channel Based on Watterson Model

Channel modeling and simulation is the basis of performance analysis and evaluation of High frequency (HF) aviation communication system. A HF aviation mobile channel model based on Watterson model is proposed by analyzing the influence of maneuvering state parameters such as maximum moving speed, acceleration, maneuvering frequency and trajectory on the time-varying Doppler frequency shift. The model can fully describe the Doppler frequency shift and spread caused by the relative movement of the transmitter and receiver, and is suitable for HF over-the-horizon aeronautical mobile communication channel. The simulation results show that the model can realize the differential simulation of HF mobile communication channels for different types of aircraft with different maneuvering states, and can realize the customized channel simulation in specific scenarios when the route path is known.
