Reduction of radar cross section of wind turbines

Materials and method to reduce the radar cross section of wind turbines

Reduction of the radar cross section is an important aspect when planning a modern wind power plant. In the European Union the building permits for more than 20GW of wind power plants are rejected till the end of 2011 because of interference with civil and military radars. This equates to an estimated value in 2011 of more than € 30 billion.
