A comprehensive understanding of the forward scattering of radar signals at the rotor of a wind turbine

Abstract

Based on an analytical description by Fresnel-Kirchhoff formula the dynamics of forward scattering of Wind turbine (WT) rotor is analyzed. This method is significantly faster than investigations by measurement or 3D numerical field simulation. Therefore, for the first time, a general comprehensive understanding of the signal modulation is presented which is beyond the investigation of a particular scenario.
