Abstract
In order to simulate distorting effects of scattering objects like wind turbines or buildings on the field strength of flight navigation systems, the influence of surrounding terrain has to be taken into account. Due to the large areas and volumes that are interspersed by the high frequency radio waves the amount of necessary main memory and computing time is very high which makes the simulation very time consuming and cost intensive. In this paper several methods to simulate the terrain influence are investigated with the attempt to minimize the simulation effort without substantive reduction of simulation accuracy. In a Doppler Very High Frequency Omnidirectional Radio Range (DVOR) environment simulation results of the electrical field strength with different treatments of the terrain are carried out and compared: completely ignoring the terrain; representing it as a flat groundplane with perfect electrical conductivity (PEC); assigning an adapted global reflection damping factor to the PEC groundplane in postprocessing; modeling the terrain as a summation of surface patches with realistic terrain texture and several adaptive reflection damping factors assigned for different areas in postprocessing. Subsequently the simulation results calculated with the investigated methods are validated by electric field strength measurements in the real environment.
