Suppression of the wind farm contribution from the atmospheric radar returns

ABSTRACT – A methodology for suppression of the returns from wind turbines in weather radar data is presented. The methodology is demonstrated on a data set provided by the Atmospheric Radar Research Center (ARRC) of the University of Oklahoma (OU) and obtained using S-band weather radar. Bootstrapping, spectral phase coherence and time Doppler spectral analysis are used to facilitate the recognition of the wind turbine contributions. These recognized contributions are suppressed in the frequency domain allowing for a recovery of the residual weather signal. This methodology is applicable for any pulse Doppler radar system and is applied to the IQ level data also known as level 1 data
