Test of HF ground wave radar OSMAR2000 at the Eastern China Sea

OSMAR2000 is a HF ground wave radar system developed by the Wuhan University of China. The system has adopted a phased array antenna with the unique working mode of "one element transmitting and eight elements receiving". The experiment of bi-stational radar detection of oceanic surface dynamics was accomplished for the first time in the mainland of China, successfully mapping the surface currents. Verification tests against in situ measurements by traditional marine instruments indicate that OSMAR2000's detecting range is 200 km for currents and wind, and 120 km for waves.
