Simulation on wind turbine radar scattering characteristics andits micro-Doppler analysis
摘要
Abstract
It is shown that wind turbines seriously affect Air Traffic Control (ATC) radars, communication and navigation equipments due to its complex electromagnetic scattering properties.The research on the wind turbine electromagnetic scattering characteristics can provide the theoretical basis for the detection and suppression of wind turbine echo, which is of vital significance for ensuring the air traffic safety.Based on the theory of scattering point superposition, the electromagnetic scattering characteristics of the wind turbine are analyzed under the condition of considering the effect of initial phase of the incident wave propagated to the blade and mast of wind turbines, and the azimuth angle and elevation angle of the incident wave.The mono-static model is expanded to bi-static model.Meanwhile, analysis of the wind turbine scattering characteristics based on hybrid model is proposed.The hybrid model combines the advantages of scattering point superposition model and FEKO, taking into account the impact of reflection coefficient of the blade and mast on the echoes.Wind turbine scattering characteristics at any observation point and micro-Doppler feature are simulated by using of scattering point superposition model, FEKO and hybrid model respectively.Finally, these methods are compared with each other and the corresponding application conditions are given.关键词
