Sandia’s Wind Turbine–Radar Interference (WT/RI) program has been investigating both wind turbines and radars for techniques to help mitigate the radar-interference issue:

  • investigating materials and techniques to reduce the radar cross section (RCS) of a wind turbine blade;
  • characterize the impact of wind turbines on current air surveillance radars, assess new technologies for near-term mitigation, and develop long-term strategies and reduce the barrier for wind-energy deployment; and
  • developing a framework that allows users to analyze potential impacts of proposed wind projects on radar systems.

These efforts utilize expertise from Sandia’s Synthetic Aperture Radar (SAR) Sensor Technologies Department as well as a partnership with the Massachusetts Institute of Technology Lincoln Laboratory.
