IMOS - ACORN - North Nambucca HF ocean radar station (Coffs Harbour, New South Wales, Australia)

The North Nambucca (NNB) HF ocean radar site (32.031 S, 115.746 E) is one of two HF ocean radars covering the waters off Coffs Harbour, New South Wales. The other HF ocean radar station is at Red Rock. \n\nThe NNB HF ocean radar is a WERA phased array system with a 16-element receive array. This radar operates at a frequency of 13.912 MHz, with a bandwidth of 100 KHz, a maximum range of 100 Km and a range resolution of 1.5 Km. Azimuthally the radar covers a sweep 60 deg either side of a bore sight direction of 285 deg true east of north (approximately west by north-west).\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.

北楠巴卡（North Nambucca, NNB）高频（High Frequency, HF）海洋雷达站（南纬32.031°，东经115.746°）是覆盖新南威尔士州科夫斯港附近海域的两座高频海洋雷达站之一，另一座雷达站位于雷德岩（Red Rock）。

该NNB高频海洋雷达为WERA相控阵系统，搭载16元接收阵列。其工作频率为13.912 MHz，带宽100 kHz，最大探测距离达100 km，距离分辨率为1.5 km。方位覆盖范围以真北基准下285°的视轴方向为中心，向两侧各覆盖60°扇区（近似西西北方向）。

在该高频雷达的覆盖区域内，可获取表层海流径向观测数据；同时还可采集相关数据，用以反演风向与有效波高。
