    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 ...

    en.wikipedia.org/wiki/Radar_astronomy

    Radar astronomy is a technique of observing nearby astronomical objects by reflecting radio waves or microwaves off target objects and analyzing their reflections. Radar astronomy differs from radio astronomy in that the latter is a passive observation (i.e., receiving only) and the former an active one (transmitting and receiving).

    A SuperDARN radar site located in Saskatoon, Canada. The Super Dual Auroral Radar Network (SuperDARN) is an international scientific radar network [1] [2] consisting of 35 [3] high frequency (HF) radars located in both the Northern and Southern Hemispheres.

  9. Radar - Wikipedia

    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.
