In order to analyze whether the HighFrequency SurfaceWave Radar (HFSWR) can be applied to detect winds from sea surface, taking the wind direction and speed from Nanpeng Island automatic weather stations (AWS) within the Yangjiang HFSWR detection range as a reference, the wind field data from HFSWR are compared with the wind data from AWS’s, and the acquisition rates of radar wind data, standard deviations, and availability are analyzed for different seasons and in such situations as wind speed between 6 to 10 m/s and less than 6 m/s. The results show that, relatively speaking, the wind direction acquisition rates and availability are high, and the standard deviation is small; wind speed acquisition rates and availability are high when the wind speed is between 6 to 10 m/s, but the availability is low at the lowspeed sea state (less than 6 m/s).
