The wind field estimated by radar OSMAR2000 at Eastern China Sea in 2000 are outlined and compared with the ship measured results. The wind direction can be provided up to a range of 200 kilometers, and the mean difference of wind direction is measured to within 20°, the agreements are fairly good. 风向 模糊性 高频雷达 wind direction ambiguity HF radar P715.7 国家 8 63计划资助项目 （863 -818-0 1-0 2 ） 2001-05-01 2021-04-01 5
