摘　　要：本文对高频地波雷达发展与应用过程中海流的对比验证研究进行了回顾与总结。不同的验证研究采用的对比设备与验证方法有所不同,但都通过海上同步观测对雷达反演的海流进行对比,经统计分析评估二者之间海流观测的差异。这些研究表明,地波雷达反演的海流流速和对比观测的均方差水平在10—20cm·s-1之间,主要来源是对比所用仪器与雷达观测目标之间的差异,仪器和雷达海流的测量误差。In this paper, we reviewed the studies on the validation of surface currents measured by high-frequency （HF） radar in terms of instrument development and application. We compared the HF radar current measurement with the conventional in-situ observations, and made statistic analysis to assess the difference between them. The validation errors of HF radar current data are about 10？20 cm·s？1. The sources of these errors are the inherent differences between the physical character of the measuring target and the observation errors of the conventional instrument and the HF radar.
