Wind turbines located near a radar installation can significantly interfere with the ability of the radar to operate properly. Remcom has used our tools and expertise in radar scattering to perform a number of government-funded and internal research efforts into the impact that wind turbines and wind farms have on radar returns for Air Traffic Control (ATC) radar, early warning radar, weather radar, and instrumentation radar. Highlights of some of these effects and relevant samples and white papers are provided in this brief overview.
