| 摘 要： | 高频雷达探测海洋表面流与常规海流计测量海流是两种不同的测量方式。本文根据 2种观测方法所获取资料的不同特点 ,对引起 2种测量方法流速测量差异的主要误差进行了分析 ,并采用合适的方法对这些主要误差进行了量化估计。研究发现 ,2种测量方法取样的空间差异、时间差异以及仪器的观测误差等是构成高频雷达与常规海流计测量结果差异的主要因素。充分考虑这些因素对流速测量的影响能较大的提高高频雷达流速对比验证的精度

| Abstract: | In this paper, based on the data of "OSMAR 2000 Experiment", the results of the HF radar measurement and the ship based current meter measurement are compared. It shows that the difference of the two measurements is mainly from temporal sampling difference, spatial sampling difference and instrument errors. To validate the accuracy of OSMAR current measurement, one needs to analyze these different sources, calculate the total difference brought about by these different sources. When these error resources are properly controlled, significant improvement of the accuracy of OSMAR can be made. |
