Accurate prediction of EM scattering by wind turbines

Very accurate simulation results are required to evaluate the shadowing effects caused by wind turbines, which may easily influence the range of operation of a radar system. Thus, the accuracy of the simulations plays an important role in such studies. However, real scenarios are generally much too complex for full-wave methods but can be treated using high-frequency simulations. This paper focuses on wind turbine simulations using a ray tracing approach, and evaluates the accuracy of results by comparison with a full-wave method in a simple environment.
