Abstract

The authors show the results of the first attempt to map vector ocean surface currents using dual over-the-horizon radars. The test used the US Navy ROTHR radars in Virginia and Texas to illuminate, via ionospheric reflection, two 70000 km² areas in the Florida Straits, approximately 1500 km from the radars. Each radar maps radial currents, which are interpolated to a common grid and combined into vector currents. Details of the Florida current and ancillary flows are seen with 10-15-km resolution
