    Abstract
    Mitigation of the impact of wind turbine (WT) forward scattering on radars, navigation systems and terrestrial radio links requires accurate modelling and rapid calculation of diffraction of RF and microwave signals at the tower and rotor of WTs. A proper analysis by 3D numerical field simulation is very time consuming as the problem is electrically extremely large. We are using 2D Fresnel-Kirchhoff diffraction formula and speed up numerical integration using Babinet's principle. Furthermore, perfect conducting and real ground plane is accounted for. Time variant diffraction loss (or obstacle gain) and phase modulation as ...

    Mitigation of the impact of wind turbine (WT) forward scattering on radars, navigation systems and terrestrial radio links requires accurate modelling and rapid calculation of diffraction of RF and microwave signals at the tower and rotor of WTs. A proper analysis by 3D numerical field simulation is very time consuming as the problem is electrically extremely large. We are using 2D Fresnel-Kirchhoff diffraction formula and speed up numerical integration using Babinet's principle. Furthermore, perfect conducting and real ground plane is accounted for. Time variant diffraction loss (or obstacle gain) and phase modulation as well as time-frequency spectrum of the frequency deviation of the forward scattered signal is presented. Results are verified by numerical 3D field simulations (Uniform Theory of Diffraction).
