Wind Turbines May Be Getting Stealth Technology

High-flying wind turbines near low-flying aircraft can cause radar confusion. Military stealth technology may offer a solution.

Paul Ridden at reports:

Radar technology tracks moving objects by looking for Doppler but if an aircraft flies low over a wind farm, even though only the moving parts on a turbine are its blades the radar is unable to easily distinguish one moving object from the other.
Technology consultants, QinetiQ (which was formed after the breakup of the UK Government's Defence Evaluation and Research Agency in 2001) and turbine manufacturer Vestas believe that the solution lies in hiding the turbines and blades from the radar using stealth technology.
In a project partly funded by the UK Government, radar absorbing materials were integrated in a turbine blade which was then fitted to an existing Vestas V90 turbine. Radar cross section measurements were then taken using a system developed by QinetiQ. The results showed a significant reduction in the radar signature of the turbine" See full article:

  1. Wow very interesting blog,

    I got the information about how the Radar technology can be implemented to some other technology. Thanks for sharing this information.
