  This paper describes the use of the Murchison Widefield Array, a
low-frequency radio telescope at a radio-quiet Western Australian site, as a
radar receiver forming part of a continent-spanning multistatic radar network
for the surveillance of space. 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.
