Provided is an apparatus for detecting properties of a rotor blade of a wind turbine, the apparatus including: at least one leaky feeder configured to be arranged around the tower, an electromagnetic transmitter connected to the at least one leaky feeder and configured for transmitting a first electromagnetic signal along the at least one leaky feeder, a reflector for diverting and/or focusing the first electromagnetic signal in a predetermined direction, thereby forming a reflected first electromagnetic signal, an electromagnetic receiver connected to the at least one leaky feeder and configured for receiving a second electromagnetic signal from the at least one leaky feeder, the second electromagnetic signal being reflected from the rotor blade, and a processing unit connected to the electromagnetic transmitter and the electromagnetic receiver and configured to determine the properties of the rotor blade by analysing the first electromagnetic signal and the second electromagnetic signal.
An apparatus for detecting one or more properties of a rotor blade during operation of a wind turbine, the wind turbine including a tower, a nacelle and the rotor blade, the apparatus comprising:
A wind turbine comprising:
A method of detecting one or more properties of a rotor blade during operation of a wind turbine, the wind turbine comprising a tower and a nacelle, the method comprising:
