Radar wind turbine

A method comprising:

• affixing at least one radar antenna to a corresponding one of a plurality of blades of a wind turbine having a hub and with said plurality of blades extending therefrom;
• the radar antenna configured to transmit and/or receive a radio frequency (RF) signal;
• and
• processing radar signals transmitted and/or received via said radar antenna for detecting an airborne target;
• said radar antenna being affixed to said one of the plurality of blades of the wind turbine such that relative motion is defined between said radar antenna and said target within a line of sight of said radar antenna.

A radar wind turbine apparatus comprising:

• an electric generator in electrical communication with a power grid associated with the wind turbine;
• a torque shaft extending from a rotor of said electric generator;
• a blade assembly coupled to said torque shaft, said blade assembly comprising:
• a central hub comprising a rotational joint, said hub coupled to said torque shaft;
• a plurality of blades, each blade coupled to said central hub;
• and
• at least one radar sensor disposed on or in one of said plurality of blades.
