Fast Ray-Optical Simulation of Rotating Wind Turbines

A fast ray-optical approach for electromagnetic simulation of rotating wind turbines is presented in this paper. The simulation results are well-suited for further data processing, e.g., generation of ISAR images or spectrograms, which implies a very large number of simulations to be performed. The algorithm works with detailed 3D CAD models of wind turbines and can process thousands of time steps within considerable computation time. The paper also provides a discussion of simulation requirements as well as a brief overview of alternative simulation methods.
