Jindalee Alpha.Over ther horizon radar (receiving section)
Australia's Jindalee Operational Radar Network (JORN) comprises 3 Over-The-Horizon Radar (OTHR) systems and forms part of a layered surveillance network covering Australia's northern approaches. JORN provides wide area surveillance at ranges of 1000 to 3000 km from the radar sites and is used to conduct air and maritime surveillance. JORN was designed to detect air targets in size of fighter aircraft or larger and objects on the surface of the water in size of a patrol vessel or larger. The extent of available JORN coverage and actual system performance is variable and principally dependent on the state of the ionosphere, environmental conditions and the object's size and construction.
The first OTHR was installed at Alice Springs in 1974 under a Defence Science and Technology Organisation research program. As Project Jindalee, the Alice Springs radar was upgraded from its original design and commenced further trials in early 1982. It detected its first ship in early 1983 and its first aircraft was automatically tracked in early 1984. Project Jindalee finished in 1985.
The recommendation to acquire an operational OTHR system was adopted in 1987 when the government gave hi-priority to design and development of an OTHR network, based on the Jindalee experimental radar.
