抄録

For a routine observation of surface current by dual-site high-frequency radar(HF and VHF radar), it is absolutely necessary to develop an automatic extraction method of the surface current information from the narrow-beam sea-echo data with stable accuracy and without being checked by an expert.<br> In developing the automatic procedures mentioned above, we took full advantage of the Bragg resonant mechanism, radar measurement's characteristic and statistical analysis. Features of the developed methods are;<br> Surface currents extracted by this process are in good agreement with those measured by current meters at the same time in a bay with a dominant tidal flow, and the distribution mapped by these surface current data illustrate a well-known dominant feature in the bay.<br> The conclusion is that the developed method is valid for the purpose of a routine observation by the radar.
