Impact of wind turbines On ATC radars and mitigation results

This paper first describes the impact of wind turbines on air traffic control (ATC) radar based on theoretical modeling and simulation. Real data are collected from operational ATC radar sites surrounded by major wind farms and analyzed to demonstrate features of wind turbine signals. A series of systematic mitigation methods are proposed and implemented for the existing ATC radar to improve the aircraft detection and tracking performance over the wind farm area. The experimental results from field trials are presented to verify the effectiveness of each method.
