As a kind of renewable and clean energy, wind energy has been widespread concerned by countries around the world. However, it is shown that wind turbines will have a serious impact on Air Traffic Control (ATC) communication, navigation and surveillance systems due to the complex electromagnetic scattering properties. Therefore, analysis of the wind turbine Radar Cross Section (RCS) and micro-Doppler feature are of great significance. FEKO is a suit of professional electromagnetic analysis tool which has a large advantage of calculating the RCS of wind turbines and other electrically large objects. The RCS of wind turbines is calculated by FEKO, and the variability of wind turbine RCS with azimuth and elevation angles is analyzed in the paper. Meanwhile, in order to further present the micro-Doppler features of wind turbine echo, wind turbine echo is simulated based on FEKO and the characteristics of wind turbine echo in time domain, frequency domain and time-frequency domain are also analyzed, by which we reveal the micro-Doppler features of wind turbine caused by the rotation of wind turbine blades. The great agreement between simulation and real data confirms the validity of the FEKO simulation results in the paper.
