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 civil aviation meteorological radars, which may affect the accuracy of the meteorological observation and weather forecast. In recent years the capacity of installed wind farms in China has increased exponentially and the total capacity leaped to the first place in the world from 2010. Consequently, wind farms tend to be a larger threat to meteorological radars. In this project we will study on how to assess the wind farm’s impacts on civil aviation meteorological radars and how to suppress the wind farm’s interference on civil aviation meteorological radars. Within this framework we will do research on these three topics: the modeling of wind farm’s interference for civil aviation meteorological radars, the assessment of wind farm’s interference for civil aviation meteorological radars, the suppression of wind farm’s interference for civil aviation meteorological radars. Our work will fill the blanks of related field in China. The work is valuable for guaranteeing the accuracy of the meteorological observation and weather forecast in civil aviation and will play an important role in guaranteeing the flight safety, decreasing the scheduled flight delay and improving the operation benefits in civil aviation.
