At the bottom of an article about the hand-over of the Space Surveillance Telescope, there's the following. Passive radar for space surveillance has been an idea, and occasionally demonstrated, for thirty or more years. Perhaps, if this report is right, Australia is actually going to do it. ======= https://www.australiandefence.com.au/news/casg-takes-over-space-surveillance-telescope [Much deleted] Investments in space situational awareness are picking up, particularly through the Defence Innovation Hub. Silentium Defence was last year awarded a contract to develop a unique ‘wide-field-of-view’ space surveillance technology that will allow Australia to independently track and monitor objects in orbit around Earth. The team will use the super-sensitive Murchison Widefield Array (MWA) radio telescope to record radio waves bouncing off objects in Earth’s orbit. These objects can be 1000km away and travelling at up to 8km per second. The signals recorded by the telescope are then processed to create a passive radar. _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Thu May 23 2019 - 18:55:56 UTC
