便携式高频地波雷达东海表面流探测试验

Sea Surface Currents Detection at The Eastern China Sea by HF Ground Wave Radar OSMAR-S

便携式高频地波雷达系统(OSMAR-S)采用了线性中断调频连续波体制和单极子/交叉环紧凑型天线阵,通过双站合成得到海洋表面矢量流.2007年11月在洋山海域进行了OSMAR-S与其他海洋测量设备的表面流现场探测对比验证试验.试验采用了构成二个断面的五个定点和运用漂流浮标的一个动点同时进行的对比监测方式.试验结果表明了OSMAR-S系统的表面流测量效果与其他海洋测量设备的一致性.

Portable HF surface wave radar system OSMAR-S adopts Freguency Modulated Interrupted Continuous Waveform（FMICW） and Orthogonal Loop/Whip Antenna Arrays.OSMAR-S obtians surface vector currents by composeing two station surface radical currents.Verification tests of OSMAR-S system against in situ measurements had been accomplished on Nov.12～17,2007.A observing method of fixed five-point and a movable point simultaneity comparison was used in the test.This paper introduces the system structure of OSMAR-S system, and then presents comparison results of surface currents measurements. The results indicate the OSMAR-S system is meet the need of design.
