Abstract
The invention relates to a device for detecting icing and de-icing of a wind turbine blade, characterized in that it comprises: a sensor, placed on the surface of a blade, and comprising a first so-called “receiving” antenna, a second so-called “emitting” antenna, and a frequency divider inserted between said first and second antennas; and an interrogator, configured to emit an electromagnetic wave towards the receiving antenna of said sensor, and to receive an electromagnetic wave from the emitting antenna of said sensor.
