Expect for its military purposes,HF Ground Wave Radar（ GWR） has been widely used in the remote sensing for sea state such as the measurememts of surface current,wind direction and wave parameters.In this paper,a new high- resolution array processing method,based on the direction finding for broad beam antenna by using of high- frequency ground wave radar remote sensing the scattering characteristic from ocean surface,is presented.According to the radar operational mechanism,the practically engineering programme is illustrated. 高频地波雷达 数字波束形成 高分辨算法 high- frequency ground wave radar digital beam froming high- resolution array processing 10.14188/j.1671-8836.2000.05.027 TN95 国家 8 63计划资助项目!（ 818-0 1-0 2 ） 2000-05-01 2021-04-01 5
