The Jindalee Operational Radar Network (JORN) is an over-the-horizon radar (OHR) network operated by the Royal Australian Air Force (RAAF) that can monitor air and sea movements across 37,000 square kilometres (14,000 sq mi). It has a normal operating range of 1,000–3,000 kilometres (620–1,860 mi). The network is used in the defence of Australia, and can also monitor maritime operations, wave heights, and wind directions.

JORN's main ground stations comprise a control centre, known as the JORN Coordination Centre (JCC), at RAAF Base Edinburgh in South Australia and three transmission stations: Radar 1 near Longreach, Queensland, Radar 2 near Laverton, Western Australia and Radar 3 near Alice Springs, Northern Territory.
