| Abstract: |
| The high frequency(HF)ground wave radar (GWR) is emerging as a significant tool for monitoring ocean surface condition at ranges well beyond the line-of-sight horizon that limits conventional systems.Experiments and theory 30 years ago demonstrated the utility and accuracy of HF radar for mapping ocean surface currents,waves,and winds.This paper reviews the long history of this evolution to operational,describes the technique specifications and operational circulation of OSMAR2000(Ocean State Measuring and Analyzing Radar, in 2000,Wuhan University, China).Finally,the authors analyse several improvements underway to the present state of the technology. |
