Measurement and analysis of the radar signature of a new type of wind turbine

We present the results of measurements of the radar signature of a new type of wind turbine, named the Wind Lens. This design includes a shroud around the turbine which concentrates the wind flow past the turbine blades and hence improves the efficiency. The design also offers improved safety, and reduces acoustic noise. Furthermore, it may offer a significantly lower radar signature, which may make the design much more attractive for use in situations where conventional wind turbine designs may disturb the operation of radars in an unacceptable manner.
