英文摘要： As a source of clean energy wind power has attracted great interests around the world. Recent research reveals that wind farms have serious impacts on Air Traffic Control (ATC) radars, which may threaten flight safety in aviation. In recent years the capacity of installed wind farms in China has increased exponentially and in 2010 the total capacity leaped to the first place in the world. Consequently, wind farms tend to be a larger threat for flight safety in China. In the present work we study on the evaluation of the wind farms impacts on ATC radars on one hand. In particular, models for qualitative and quantitative evaluation will be constructed and correspondingly an evaluation software is to be developed. On the other hand, problems in mitigating the interference induced by wind farms will be solved. This is the focus of the work. Within this framework the simulation of radar echo signals of wind farms and signature extraction of electromagnetic field scattered by wind farms will be performed. Algorithm for mitigating the interference created by wind farms is to be developed. Our work will fill the blanks of related field in China. The results can be used for site selection of potential wind farms and ATC radars. From this aspect the work is valuable for the flight safety guarantee in civil aviation as wel
