Abstract:

Research shows that wind farms may affect and degrade ATC radar systems. Assessing the impact accurately is one of the key issues to solve the problem. An impact assessing approach of wind farms is proposed on secondary surveillance based on signal characteristics. The impact of wind turbines is analyzed first based on the signal characteristics of secondary surveillance radar. Then the evaluation methods based on reflected signal delay is described. Finally,the method is verified through the simulation experiment based on DEM (digital elevation model)data.

Key words: wind farm, secondary surveillance radar, reflected signal, impact assessment
