Abstract:This paper discusses the parameters in the model troposphere waveguide horizontal non-uniformity. The paper uses the parabolic equation method, the simulation analysis of evaporation duct height and the height of the base level of the inverter layer non-uniformity on tropospheric wave waveguide path loss distribution under the influence. Simulation results show that under certain conditions, the level of evaporation duct height non-uniformity can not be ignored, and thus propose a new model of tropospheric waveguide. In addition, the paper also applies the new path loss model for the inversion. Simulation results show that the new model can effectively improve the inversion effect.
Keywords:tropospheric duct  path loss  evaporation duct height  horizontal inhomogeneity
