TINYSAR PROJECT

A miniature multi-role radar for uncrewed air systems (UAS).

Mission Systems is developing tinySAR, a miniature multi-role radar for uncrewed air systems (UAS). Funded through the Australian Defence Innovation Hub, each sub-1kg module will provide detect and avoid (DAA) sensor data to enhance operation of autonomous aircraft in controlled airspace, as well as synthetic aperture radar (SAR) imaging at stand-off ranges. Designed and developed in Australia in partnership with Altum RF, Syndetic, AMSL Aero and the University of Sydney, flight testing will commence in 2023.

ANSYS HFSS has been used to simulate the 2-D conformal antenna array with good agreement to anechoic chamber measurements. With real-time on-board processing, the ability to provide long-range, high-resolution imaging in all weather also opens up a range of additional application areas, either independently or as a complement to other on-board sensors.
