Wind turbine component 50 has an outer shell 11 defining an internal cavity 37, where at least a part of the outer shell is adapted to transmit incident radar signals 52a into the cavity and where one or more reflective components 15 inside the cavity are adapted to absorb radar signals. Preferably the outer shell has a frequency selective surface embedded within it. Radar absorbing material, such as a radar absorbing panel 54, may be applied to the reflective components and the reflective component may be a metallic part of a lightning protection system. Preferably the reflective component is a cable 14 attached to a surface and the panel is omega shaped in cross section such that the round part of the omega profile covering the cable and legs of the omega being bonded to the surface. A method of reducing the radar cross section is also claimed. |
