The radar signature of the Wind Lens: a less disruptive wind turbine? [PDF]
, 2012 We study the radar signature of a new type of wind turbine, named the Wind Lens. This design includes a flanged shroud around the turbine which concentrates the wind flow past the turbine blades and hence improves the efficiency.
