The transition to polarimetric (dual-polarised) radars began in 2017 with the upgrade of 4 Meteor 1500 radars located in Melbourne, Brisbane, Adelaide, and Sydney. [7] The network has further been enhanced through the installation of 8 new polarimetric Meteor 735 radars across WA, [8] NSW [9] & Victoria, [10] and two polarimetric WRM200 radars [11] manufactured by Vaisala, one to replace the ...
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).
A massive supercell with cloud tops as high as 77,000 ft (23 km) tore through Brisbane and parts of Southeast Queensland, producing several tornadoes along its path. A combination of straight line winds and a tornado ripped the roofs from 500 houses, damaged 1000 houses, and left 12 structurally unsafe in the city of Redcliffe (approximately 25 ...
The monopulse radar Cyrano I is located in the nose of the aircraft, in a pressurized enclosure. The antenna, with a diameter of 0.36 m, is movable in both Inclination and azimuth, using servo mechanisms. It includes a transmitter and a receiver. The transmitter, with a peak power of 300 kW in the band (λ = 3 cm), is a 4J 50 type magnetron.
Post-World War II radar stations included those of the 1948 "five-station radar net" and the Lashup network completed in 1950, followed by the "Priority Permanent System" with the initial (priority) radar stations completed in 1952 [3]: 223 as a "manual air defense system" [4] with Manual ADCCs (e.g., using Plexiglas plotting boards as at the 1954 Ent Air Force Base command center for ADC.)

The AN/FPS-24 Radar was a long range early warning radar used by the United States Air Force Air Defense Command. It used a two-frequency signal in order to avoid fluctuation loss, which causes signals on single-frequency radars to fade in and out as the target moves. Reducing this effect results in a much steadier signal.
Lytton Hill - also known as Signal Hill, Reformatory Hill, or the Lytton Redoubt - is highly significant in Queensland history. Strategically positioned at the mouth of the Brisbane River, the hill has been used as a customs lookout, signal and telegraph station, observation post and redoubt commanding the Fort Lytton defence complex, and boys' reformatory.
Systems in Wesley Hospital and St Andrews Hospital in Brisbane, Australia, were affected. [58] The Central Health information system in Croatia was affected, although it was clarified that it was due to a concurrent issue tied with moving their servers to a new location. [215] In Israel, Magen David Adom and its emergency service hotline was ...
