Abstract

Nautical X-band radar (low-cost option with the antenna beamwidth 1:9 ) was applied for monitoring surface near-shore currents in the Black Sea Field Research Facility of the Southern Branch of P. P. Shirshov Institute of Oceanology. The radar signal was processed by an algorithm based on the Nieto-Borge approach. The experimental setup is shown to allow precise real-time near-surface current measurements up to 4 km oshore. A case study of a coherent current pattern resembling a sub-mesoscale vortex passing the experimental eld is presented. KEYWORDS: X-band radar; radiowave oceanography; currents; sub-mesoscale vortex; Black Sea.
