This paper details the system geometry employed, the orbit-specific radar signal processing, and the orbit determination algorithms necessary to ensure resident space objects are detected, tracked, and propagated. Finally, the paper includes the results processed after a short collection campaign utilising several FM radio transmitters across the country, up to a maximum baseline distance of over 2500 km. The results demonstrate the Murchison Widefield Array is able to provide widefield and persistent coverage of objects in low Earth orbit.<\/jats:p>","DOI":"10.3390\/rs14112571","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T02:30:06Z","timestamp":1653964206000},"page":"2571","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Establishing the Capabilities of the Murchison Widefield Array as a Passive Radar for the Surveillance of Space"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8136-9365","authenticated-orcid":false,"given":"Brendan","family":"Hennessy","sequence":"first","affiliation":[{"name":"International Centre for Radio Astronomy Research, Curtin University, Bentley, WA 6102, Australia"},{"name":"Defence Science and Technology Group, Edinburgh, SA 5111, Australia"}]},{"given":"Mark","family":"Rutten","sequence":"additional","affiliation":[{"name":"InTrack Solutions, Adelaide, SA 5000, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5348-9693","authenticated-orcid":false,"given":"Robert","family":"Young","sequence":"additional","affiliation":[{"name":"Defence Science and Technology Group, Edinburgh, SA 5111, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8195-7562","authenticated-orcid":false,"given":"Steven","family":"Tingay","sequence":"additional","affiliation":[{"name":"International Centre for Radio Astronomy Research, Curtin University, Bentley, WA 6102, Australia"}]},{"given":"Ashley","family":"Summers","sequence":"additional","affiliation":[{"name":"Defence Science and Technology Group, Edinburgh, SA 5111, Australia"}]},{"given":"Daniel","family":"Gustainis","sequence":"additional","affiliation":[{"name":"Defence Science and Technology Group, Edinburgh, SA 5111, Australia"}]},{"given":"Brian","family":"Crosse","sequence":"additional","affiliation":[{"name":"International Centre for Radio Astronomy Research, Curtin University, Bentley, WA 6102, Australia"}]},{"given":"Marcin","family":"Sokolowski","sequence":"additional","affiliation":[{"name":"International Centre for Radio Astronomy Research, Curtin University, Bentley, WA 6102, Australia"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e005","DOI":"10.1017\/pasa.2015.6","article-title":"The high time and frequency resolution capabilities of the Murchison Widefield Array","volume":"32","author":"Tremblay","year":"2015","journal-title":"Publ.
