摘要
为了验证采用紧凑型接收天线的便携式高频地波雷达系统(OSMAR-S)的探测性能,于2007年11月在洋山海域进行了OSMAR-S与其他海洋测量设备的现场探测对比验证试验。试验设计了定点固定水深测量与坐底剖面测量相结合的连续现场对比监测方式,把雷达获得的表面流探测数据与其他设备得到的不同深度的海流观测数据进行对比。通过试验数据分析,OSMAR-S系统的探测深度和精度都得到了验证,能够满足实时监测海洋表面流的需要。同时试验也填补了高频雷达探测深度没有试验验证的空白。
In order to test the measurement capability of HF ground wave radar system (OSMAR-S) with compact receiving antenna,verification tests of OSMAR-S system againstin situ measurements had been accomplished on Nov. 12~17,2007. A observation method is used in the test for continuously comparison. The method is composed of fixed point survey at fixed depth and section survey at bottom,and compared the surface current data acquired by OSMAR-S with different depth current data acquired by others. The results confirm the detection precision and depth of OSMAR-S and indicate OSMAR-S is meet the need of sea real-time monitoring. The test also fill the blank that it is no test to confirm the detection depth of HF ground wave radar.
