| 摘要: |
| OSMAR-S系列便携式高频地波雷达系统采用单极子/交叉环紧凑型天线阵,通过单站雷达即可实现有效探测距离约10km内海浪和海面风的单点观测。为了更好地了解OSMAR-S100雷达系统海浪和海面风的综合探测性能,于2013年1月29日至3月7日在台湾海峡西南部海域进行了雷达与浮标观测的对比试验,得到了有效波高、有效波周期、平均风速和平均风向数据。对比结果表明,OSMAR-S100便携式高频地波雷达可有效观测距雷达10km以内有效波高0.5m以上的海浪平均状况和平均风速5m/s以上的海面风,雷达反演有效波高和有效波周期的均方根误差分别为0.60m和1.60s,反演平均风速和平均风向的均方根误差为1.83m/s和16.7°。在未经区域化标定的情况下,此结果说明了该型雷达产品已初步具备了海浪和海面风的业务化观测水平。 |

| Abstract: |
| 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 10km 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 0.60m for wave height, 1.60s 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. |
