Analysis of the effect of wind turbines in SAR images

The presence of wind farms rose significant problems in the radar community, principally for meteorological and air traffic control radar. The presence of active wind turbines can affect also radar imaging systems that monitor ground and sea areas where windmills are often present. The blade motion introduces Doppler effect on the returned echoes to the SAR platform that can introduce undesirable effects in the final image. In this paper the effect of active wind turbines in focussed SAR images is modelled and the effect for different aspect angles and rotating blade velocities are analysed through simulations.
