Analysis of the frequency and time variation of radio signals scattered by a Wind Turbine

In this paper, the effect on radiopropagation of VHF and UHF signals when interacting with Wind Turbines is presented. Due to the large size of the Wind Turbines, simulation of the Radar Cross Section is performed, taking into account the movement of the blades. In-house finite element code simulations as well as field measurements are presented, showing that frequency dispersion due to the blade movement is present.
