Measurements for Classification of Single Wind Turbine Echoes

A passive bistatic radar (PBR) constellation of a radar transmitter, wind turbines as targets and an unmanned aerial system (UAS) carrying the receiver is used for scattering measurements and discrimination between single wind turbine (WT) echoes. Since the geometry is fully known, the radar echo gained from the WT is related to its reflectivity across the flight altitude of the UAS. These results are compared against computer simulations of the same scenario.
