1. A method for measuring ocean surface currents using a long-range single station high frequency ground wave radar system, said method comprising the steps of: (a) selecting a target region with a uniform surface current flow from a coverage area of said single radar system; (b) spanning said target region with a predetermined plurality of radial beam lines from said single radar station; (c) dividing each radial beam line into a pre-selected plurality of radial sub-nodes; (d) measuring, with said single radar system, radial surface current vector projection at each radial sub-node; (e) inputting each radial surface current vector projection into a multiple regression model having two regressors; and (f) determining, with said multiple regression model, surface vector component values along each of x and y axis.
