Methods of Designing and Feeding Carbon Fibre Reinforced Plastic Slotted Waveguide Antenna Arrays

This report describes the ongoing development of the Slotted Waveguide Antenna Stiffened Structure (SWASS) technology during the period 2010 to 2012.

Evaluation of a Distributed Fibre Optic Strain Sensing System for Full- Scale Fatigue Testing

This report details an experimental comparison between the performance of conventional electrical resistance foil strain gauges and a commercially available fibre optic distributed strain measurement system based on Rayleigh scattering. 

High Range Resolution Backscatter Sounder Ionograms

This paper describes methods used for high range resolution processing (6.1 km for 3 frequencies per 100 kHz) of the same raw data including superior radio frequency interference rejection.

Flow Visualisation Around a Hemispherical Protuberance in the DST Group Water Tunnel

The flow structures around a hemispherical protuberance were studied using dye-injection flow visualisation in the DST Group Water Tunnel. A 100 mm diameter hemisphere was placed in a laminar oncoming boundary layer, and video imaging of the dye streamlines were captured at diameter-based Reynolds numbers of 6:91 x 10^3 and 1:15 x 10^4. The observations generally agree well with previous studies, while analysis of the video footage has provided additional insight into the evolution of the unsteady flow field.

Adversarial Machine Learning for Cyber Security: NGTF Project Scoping Study

This report is the result of a scoping study undertaken as part of an Australian Department of Defence Next Generation Technologies Fund (NGTF) project entitled Adversarial Machine Learning for Cyber- Security (AMLC).

An Investigation into the Possibility of Numerical Ephemeris Extension for GPS

The possibility of a purely numerical extrapolation of parameters to extend the period of validity of any given set of GPS ephemeris parameters is investigated in this report.

The Operationalisation of Agent Transparency and Evidence for Its Impact on Key Human-Autonomy Teaming Variables

This report provides a review of studies that have examined how the transparency of an autonomous system affects key variables such as operator performance, response time, situation awareness, perceived usability, and subjective workload.

Expressing Sensor Maturity in Terms of Information Fusion: Re-defining Non-Traditional Sensing

This paper explores the definition of non-traditional sensing (NTS), some of the technologies that are typically associated with NTS and, ultimately, questions the need for NTS as a concept.
