IMOS - ACORN - Tannum Sands HF ocean radar station (Capricorn Bunker Group, Great Barrier Reef, Queensland, Australia)

The Tannum Sands (TAN) HF ocean radar site (-23.942 S, 151.371 E) is one of two HF ocean radars covering Heron Island in the Capricorn Bunker Group (CBG) in the southern region of the Great Barrier Reef Marine Park World Heritage Area. The other HF ocean radar station is at Lady Elliot Island. The HF ocean radar coverage is from the coast to beyond the edge of the continental shelf. \n\nThe TAN HF ocean radar is a WERA phased array system with a 12-element receive array. This radar operates at a frequency of 8.348 MHz, with a bandwidth of 33 KHz and a maximum range of 200 Km and a range resolution of 4.5 Km. Azimuthally the radar covers a sweep 45 deg either side of a bore sight direction of 47 deg true east of north (approximately north-east).\n\nWithin the HF radar coverage area surface current radials are measured. Data are also collected from which wind directions and significant wave height can be calculated.\n\nThis station was decommissioned in April 2017.

塔努姆桑兹（Tannum Sands，简称TAN）高频（HF）海洋雷达站（南纬23.942°，东经151.371°）是覆盖大堡礁海洋公园世界遗产区南部摩羯座班克群岛（CBG）内赫伦岛的两座高频海洋雷达站之一，另一座高频海洋雷达站位于埃利奥特夫人岛。该高频海洋雷达的覆盖范围从海岸延伸至大陆架外缘以外。

TAN高频海洋雷达为WERA相控阵系统，搭载12元接收阵列。该雷达工作频率为8.348 MHz，带宽33 kHz，最大探测距离达200千米，距离分辨率为4.5千米。在方位维度上，该雷达以北偏东47°（近似东北方向）为视轴方向，可覆盖该方向两侧各45°的扇形扫掠区域。

在该高频雷达的覆盖范围内，可测得表层海流的径向分量数据；同时还可通过采集到的原始数据计算得到风向与有效波高参数。

该雷达站已于2017年4月退役。
