Evaluation on EM Scattering Properties From a Wind Farm by an Efficient High-Frequency Method

In order to study the dynamic signature from a wind farm composed of massive wind turbines, a high-frequency model of electromagnetic scattering is developed by combining a shooting and bouncing ray and the array synthesis technique. With the help of image theory and some modifications, the ground effects due to a dielectric rough ground are accounted whereas without modeling physically the infinite ground. Thus, the proposed method can be used to effectively simulate the massive required scattering data under a minimal computational cost for the Doppler analysis of the full-size rotating wind turbines and radar imaging of a wind farm.
