Özet

Radar systems have been facing some deteriorating effects of wind turbines with the increasing investments on wind power technology all over the world. Due to electrically large dimensions and rotational blades which cause additional Doppler shift, wind turbines might be deteriorating on SAR imaging systems that use Doppler shift of static ground targets to extract cross range information. In this paper, a wind turbine is modeled as a combination of smaller canonical segments, and for different wind turbine-SAR sensor orientations, possible deteriorating effects of wind turbine to SAR imaging is investigated by taking into consideration of both the time dependent phase and RCS variation of turbine segments.
