Methodology for the empirical analysis of the scattering signals from a wind turbine

This study proposes a field data-based methodology to characterize the scattered signals from wind turbines. The method is based on the scattering pattern of the wind turbine, empirically obtained from the estimation of the channel impulse response, which allows the accurate estimation of the amplitude and the time variation of the scattered signals. The analysis of the Channel Impulse Response at different situations, such as the rotation speed, the orientation of the turbine or the elevation and azimuth angles of the receiver location, will allow the proper characterization of this phenomenon, and therefore, the development of an empirical model for the estimation of the potential interference of wind farms.
