Along with the deployment of low Earth orbit satellite constellations for global satellite Internet services, such as Starlink, Ku/Ka/V band microwave signals from space will be available anywhere on Earth 24/7. Utilising the microwave signals, this project aims to investigate a high-resolution cost-effective solution to position and track un-cooperative flying objects, and expects to generate new knowledge in the area of remote sensing and to make Australia the leader in passive flying objects positioning and tracking. This should provide significant benefits, such as enabling new applications for future drone delivery systems or aerial taxi services, and benefiting the air transport industry, the defence industry, and bird conservation.Read moreRead less
The Global Fireball Observatory: Illuminating Solar System Origins. Virtually everything we know about the origin and evolution of our solar system comes from analysis of meteorites. But reading the record they contain has proven to be difficult: we have almost no constraint on where they come from. With ARC LIEF support, Australian planetary scientists are leading a consortium of 14 international teams to build a Global Fireball Observatory.

Virtually everything we know about the origin and evolution of our solar system comes from analysis of meteorites. But reading the record they contain has proven to be difficult: we have almost no constraint on where they come from. With ARC LIEF support, Australian planetary scientists are leading a consortium of 14 international teams to build a Global Fireball Observatory. The facility, with a unique global footprint, will be complete by end-2019. It will track 100s of meteorite falls, and for each one, pinpoint its origin in the solar system. A NASA partnership will provide administrative support. Curtin University will fund its operation. The proposal here is for a researcher and student who can drive the science program.Read moreRead less
Exploring solar system origins with the Desert Fireball Network. This project aims to explore the science delivered by the Desert Fireball Network (DFN), a continent-wide facility comprising dozens of observatories across remote and regional Australia, tracking material entering the atmosphere. Meteorites record early solar system processes, but there is no constraint on where they come from. Precise orbits for recovered meteorites can solve that problem. This project will use the largest datase ....Exploring solar system origins with the Desert Fireball Network. This project aims to explore the science delivered by the Desert Fireball Network (DFN), a continent-wide facility comprising dozens of observatories across remote and regional Australia, tracking material entering the atmosphere. Meteorites record early solar system processes, but there is no constraint on where they come from. Precise orbits for recovered meteorites can solve that problem. This project will use the largest dataset of fireball orbits ever acquired, while a supercomputer imagery archive provides a way-back machine for researchers. DFN tracking of satellites, debris re-entry and overseas rocket launches directly benefits Australian national security and a mature outreach programme aims to deliver the outcomes of this research to the public.Read moreRead less

This is expected to contribute to Australian industry sectors, thereby benefiting the Australian economy, society, environment, and national security.Read moreRead less
Parameter estimation for multi-object systems. Parameter estimation in multi-object system is essential to the application of multi-object filtering to a wider range of practical problems with social and commercial benefits. This project develops the necessary parameter estimation techniques for complete 'plug-and-play' multi-object filtering solutions that facilitates widespread applications.

The project aims to develop a conceptual framework and algorithms for handling multi-vehicle formation control. Formations of unmanned airborne vehicles are currently used by defence forces and swarms of micro-vehicles are beginning to find increasing use in defence and for civilian emergency response, largely for surveillance purposes. Vehicles must cooperate to achieve a global formation objective, while respecting constraints on sensors, energy, and general mechanical limitations. The project aims to resolve the challenges of deciding what a single vehicle should observe, what and to where it should communicate, and how it should move in relation to what it sees. The conceptual framework developed may also be relevant in guiding future defence acquisitions and civilian applications.Read moreRead less
New insights into fundamental carrier transport in type-II superlattices. Type-II superlattice (T2SL) based semiconductors have emerged as a rival to well-established HgCdTe-based IR detectors, promising comparable performance at significantly lower cost. T2SLs are complex nanostructures that exhibit multiple-carrier and highly-anisotropic electronic transport properties, which renders them exceedingly challenging to study experimentally.

Type-II superlattice (T2SL) based semiconductors have emerged as a rival to well-established HgCdTe-based IR detectors, promising comparable performance at significantly lower cost. T2SLs are complex nanostructures that exhibit multiple-carrier and highly-anisotropic electronic transport properties, which renders them exceedingly challenging to study experimentally. The lack of reliable experimental data has limited optimisation and modelling efforts, and thus hampered progress. This project aims to systematically study electronic transport in T2SLs, both experimentally and theoretically, by employing world-leading mobility spectrum techniques developed at UWA and state-of-the art T2SL structures from three world leaders in T2SLs.Read moreRead less
