Technical report
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.
Technical report
This report describes the ongoing development of the Slotted Waveguide Antenna Stiffened Structure (SWASS) technology during the period 2010 to 2012.
Technical report
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.
Technical report
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.
General document
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.
Technical 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.
Technical report
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.
Technical note
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.
Research report
In this report a side-by-side comparison with in-service CRP, a nutrient optimised modular MA CRP design is fielded with dismounted infantry personnel to assess fitness-for-purpose and utilisation over a 6–day use period.
