In the ocean surface, there are currents generated by ocean winds. Wind driven-currents are nonstationary phenomena temporally and spatially. Wind driven-currents affect coastal currents. Therefore, the grasps of wind-driven currents are important. It is necessary to observe velocity of currents temporally and spatially due to estimate wind-driven currents. However, it is difficult to observe spatial velocity of currents and ocean winds by current meter and anemometer of stationary type. High frequency (HF) radar can be observed spatial velocity of currents. Although ocean winds cannot be measured directly by HF radar, it is possible to estimate using wave height, wave period, and the Sverdrup-Munk-Bretschneider's (SMB) method.<BR>In this study, ocean winds were estimated by obtained wave height and period from HF radar and SMB method. In addition, wind-driven current was presumed using the estimated wind and bulk method. Finally, we developed self-contained estimation system of wind-driven system currents using high frequency radar.
