The use of wind farms to generate electricity isgrowing increasingly due to the importance of being a renewableenergy source. These installations can have over a hundredturbines of up to 120 m height each. Moreover, windmills areexpected to be significantly higher in a few years, with blade tipheights reaching 200 m. This continued growing both in thenumber and the height of the wind farms is seriously threateningthe correct performance of weather radars. In this work we willanalyze the Doppler spectral content of the wind turbine cluttersignal. The experiments, made with the aid of the Spanishweather radar network, had two main goals: gather data innormal operation mode and in spotlight mode. This will show thewind turbine clutter Doppler spectrum as functions of azimuthangle and time.
