Abstract: As a kind of clean energy and renewable energy, wind energy has been widespread concerned by the countries around the world in recent years. Wind turbine will have an adverse impact on air traffic control (ATC) surveillance radar located nearby. The study of wind turbine clutter detection technology plays an important role for ensuring the air traffic safety of civil aviation aircraft. The clutter detection method based on micro-Doppler characteristics of wind turbine radar echoes is presented. The method realizes wind turbine clutter detection by using of micro-Doppler characteristics of wind turbine clutter under the condition that wind turbine and radar beams are at different position. The range cell in which wind turbine clutter exists needs to be further determined whether there is a plane target. Then clutter mitigation method only works for the range cell where plane target exists.
