面向低空风场的雷达探测技术综述OA

Under the"dual carbon"goals of carbon peaking and carbon neutrality,wind power generation is of great significance to the stable operation of the power grid,and real-time,accurate wind measurement equipment is crucial for addressing wind turbine operation and maintenance challenges and improving the economic benefits of power generation.This paper first reviews the development of wind measurement technology from passive mechanical devices to active wind measurement radars.Secondly,it elaborates in detail on three types of wind measurement radars:Sonic Detection And Ranging(SODAR),which uses aerosol particles as detection targets and is susceptible to environmental noise interference,with its anti-noise performance enhanced through methods such as ground clutter suppression using Gaussian mixture models;Light Detection And Ranging(LIDAR),which also uses aerosol particles as detection targets but is greatly affected by weather conditions,with its detection accuracy improved through technologies such as pseudo-random phase coding;and Microwave(MW)radar,which uses atmospheric turbulence as detection targets but suffers from insufficient accuracy and low temporal resolution,with its detection accuracy and temporal resolution enhanced through methods such as multi-beam antennas and beam rotation.Finally,the paper compares and summarizes the above three types of wind measurement radars,and further prospects the future breakthrough directions and development trends of radar technology for low-altitude atmospheric wind fields.
