This report describes the ongoing development of the Slotted Waveguide Antenna Stiffened Structure (SWASS) technology during the period 2010 to 2012.
Our scientific and technical publications are an important vehicle for the dissemination of our work.
We have several goals for our publications:
- To communicate the results of the research program to clients and fulfil our reporting responsibilities to the Department of Defence.
- To record the results of our research program.
- To communicate the results of scientific research and technical information to Australian industry and academia.
- To increase awareness of and enhance the reputation of DST Group.

This technical note considers a sensor that alternates randomly between working and broken versus a target that reluctantly gives away glimpses as a homogenous Poisson process.
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.
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.
The widely studied generic submarine hull form SUBOFF is used to benchmark the use of the Australian Maritime College's cavitation tunnel for hydrodynamic measurements on submarine models in this report.
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.
In this report, a calibration of the pressure rings in the DST Group Research Wind Tunnel was performed for an empty test section and with an elevated ground plane installed.
Soldiers rarely consume all the food components issued in combat ration packs (CRP), compromising the adequacy of nutrient intake and the physical and cognitive performance of combatants. Mission adaptive (MA) nutrition—providing soldiers with optimal energy and nutrients when Army operates in contemporary environments and with changing demands—is thought to mitigate risk to performance. In a side-by-side comparison with in-service CRP, a nutrient optimised modular MA CRP design was fielded with dismounted infantry personnel to assess fitness-for-purpose and utilisation over a 6–day use period. Inadequate energy and nutrient intakes were identified as a result of the field trial. A detailed understanding of combatant energy expenditure, current and future risks to health and well-being and performance targets is required to optimise the design and provide a proof of concept. Further product development, potentially including formulated, energy-dense, and commercial-off-the-shelf components, is required to rectify the inadequate delivery of nutrients. Successful implementation of a MA CRP design will require training, education, policy and procedure, and interactive tools for verification of learning, validation of desirable behaviour and realisation of benefits. To provide a proof of concept, further trials are required to assess performance in various operational environments over longer use periods of up to 30 days.
This report documents a literature review of the methods associated with embedding a JVM into a Field Programmable Grid or Gate Array (FPGA).
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).
