Abstract
Radar doppler deviation caused by the time variant diffraction of the two-way signal at the rotating blades of a wind turbine (WT) is analyzed based on a one-dimensional Fresnel diffraction approach. In order to provide an insight into the degradation of the radar performance, time variant forward scatter path loss, phase shift and corresponding frequency shift are investigated.
