OSMAR-S is a portable high frequency surface wave radar(HFSWR) system with built-in orthogonal loop/whip antenna arrays. To evaluate the performance of the system, we detected the mean wave and wind field in an effective detection area of 10 km in the southwestern Taiwan Strait during Jan. 29––Mar. 7, 2013 with the radar and a buoy, and their measurement data were compared. Results show that performance of the radar was good, as it can well detect the average wave height 0.5m and averaged wind speed 5m/s. The root mean square error(RMS) of inversion calculation was 0.60 m for wave height, 1.60 s for wave period, 1.83m/s for wind speed, and 16.7° for wind direction. Therefore, the radar system is robust and can be promoted for real time application for monitoring wave and wind under rough sea conditions.
