| Zusammenfassung | The disturbing effects of scattering objects such as wind turbines (WTs) and other buildings on the flight navigation aid Doppler very high frequency omnidirectional radio range (DVOR) have been addressed in previous publications. Nevertheless, a practically feasible possibility to precisely and consistently predict the DVOR bearing deviation before the buildings' construction is still missing. In this contribution, a method based on numerical simulations is presented which allows calculating the DVOR receiver's antenna voltage in the time domain for dynamically disturbed environments. Separating its frequency modulated and amplitude modulated content, the indicated DVOR bearing is calculated subsequently by determining the corresponding phase difference. Finally, the calculation results are validated by in situ measurements of DVOR signal disturbances in the environment of eight WTs. |
