Jindalee Operational Radar Network
The Jindalee Operational Radar Network ( JORN ) is the Australian over-the- horizon radar network. The system can locate sea and air movements within an area of 20 million km².
The official range of the system is 3000 km, but under favorable atmospheric conditions it can extend to mainland Korea. It serves the defense system of Australia and can document sea movements, wave heights and wind directions. The establishment of the network has cost around 1.8 billion Australian dollars to date.
history
In the early 1970s, the Defense Science and Technology Organization (DSTO) began research into an over-the-horizon radar system (OTHR). It was not until 1987 that a government Defense White Paper gave the project higher priority, as an OTHR was seen as the most cost-effective solution for monitoring large parts of the area around Australia. In December 1990 the government decided to set up the JORN system. In 2009 JORN was completed with the 5th construction phase.
Stations
Each JORN radar station has a separate transmitting and receiving point. The stations are:
- the Queensland transmitter in Longreach
- the Queensland receiver in Stonehenge, ( Queensland )
- the West Australian transmitter in Leonora , with a coverage of 180 ° and
- the West Australian receiver in Laverton , with 180 ° coverage
The research and experimental station:
- the Alice Springs transmitter in Harts range , with 90 ° cover and
- the Alice Springs receiver in Mount Everard , with 90 ° coverage
The Alice Springs radar was originally the 'Jindalee Stage B' test site, based on the model of which the stations in Queensland and Western Australia were built. The station continues to be used as an experimental and research station.
