山东半岛地波雷达监测数据集

高频地波雷达数据集基于X波段导航雷达，通过多台设备配合使用，经科学系统的规划，建立地波雷达观测组网和数据中心，在保证数据安全的前提下，形成一套数据集实现数据共享。该数据集包含山东半岛沿海区域的近岸海表洋流速度和方向，数据覆盖范围广，能够获取雷达探测范围内任意位置海况信息，可实现数万平方公里的全自动、全天候实时海流观测。采用国际领先的SWEEP、EOF等多种算法融合，反演结果更加精准，可测得海流0-360°流向，分辨率达1°，海流流速测量范围0-5m/s，分辨率达0.1m/s。

This high-frequency ground-wave radar dataset is based on X-band navigation radars. Deployed with multiple coordinated devices, it establishes a ground-wave radar observation network and a data center through systematic scientific planning, and develops a shareable dataset while ensuring data security. The dataset covers nearshore surface ocean current velocity and direction in the coastal area of the Shandong Peninsula, with wide coverage that enables acquisition of sea state information at any location within the radar detection range. It supports fully automatic, all-weather real-time current observation over tens of thousands of square kilometers. By integrating internationally leading algorithms including SWEEP and EOF, the inversion results are highly accurate. It can measure current directions ranging from 0° to 360° with a resolution of 1°, and the current velocity measurement range is 0–5 m/s with a resolution of 0.1 m/s.
