摘　　要：为了分析高频地波雷达能否应用于海面风场探测，以广东阳江高频地波雷达探测范围内的南鹏岛自动气象站探测的风向风速为参考，将高频地波雷达探测的风场数据与之相比较，通过分析不同季节、风速6～10m／s及6m／s以下等各种情况下地波雷达探测风场数据的获取率、标准差及可用性。结果表明，相对而言，地波雷达探测风向数据获取率高、标准差较小，可用性高，而风速获取率在6～10m／s情况下较好，可用性较高，在低海况（6m／s以下）时可用性低。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）.
