Drifter Trajectory Tracking Experiment and Analysis with Multi-Frequency HFSWR in the East China Sea

We conducted the drifter trajectory tracking experi- ment for two drifters in the East China Sea, in which the currents were detected by two multi-frequency HFSWRs using the Lagrangetracking method. The tracking drifter trajectory shows good agree- ment with the GPS records by qualitative and quanti...

Summary:We conducted the drifter trajectory tracking experi- ment for two drifters in the East China Sea, in which the currents were detected by two multi-frequency HFSWRs using the Lagrangetracking method. The tracking drifter trajectory shows good agree- ment with the GPS records by qualitative and quantitative analysis that indicates that drifter tracking by HFSWR is valid. In the 12- hour tracking for drifters P1 and P2, the average errors are 1.84 kin, 1.73 kin, and the maximum errors are 3.52 km and 3.12 km, respec- tively. The current measurement is evaluated by an acoustic Doppler current profilers （ADCP） in-situ observation, and it is the first multi-frequency HFSWR ocean surface monitoring experiment in China. In addition, the main aspects （HFSWR current measurement error, wind, and wave） influencing the tracking accuracy are dis- cussed, and especially the wind factor＇s impact is analyzed through the wind filed data.
