    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 Ballistic Missile Early Warning System (BMEWS) was a radar system built by the United States (with the cooperation of Canada and Denmark on whose territory some of the radars were sited) during the Cold War to give early warning of a Soviet intercontinental ballistic missile (ICBM) nuclear strike, to allow time for US bombers to get off the ground and land-based US ICBMs to be launched, to ...

    The radar mile is the time it takes for a radar pulse to travel one nautical mile, reflect off a target, and return to the radar antenna. Since a nautical mile is defined as 1,852 m, then dividing this distance by the speed of light (299,792,458 m/s), and then multiplying the result by 2 yields a result of 12.36 μs in duration.
