Here we consider the application and suitability of the Joint Photographic Experts Group (JPEG) compression method and a simpler approach to Discrete Probability Density Maps (DPDMs).
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.

The goal of this report is, using the 2005 survey of the civilian population, to determine if a survey of the potential aircrew population could be conducted at fewer locations, hence, saving both time and money.
This report describes a radar signal processing technique for detecting helicopter targets based on the micro-Doppler components of the received signal, in a low SNR environment.
This report describes the ongoing development of the Slotted Waveguide Antenna Stiffened Structure (SWASS) technology during the period 2010 to 2012.
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 Australian Federal Police (AFP), Facial Identification - Specialist Operations Branch, commissioned the Defence Science and Technology (DST) Group to develop and deliver a training course for staff working in the forensic facial comparison domain.
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.
