Sensing and Security
Sensing is concerned with sensing the world around us, processing the data gathered to extract useful information, and understanding, exploring and controlling the behaviour of diverse systems. Security is about protecting people and assets and a significant element in any seurity system is the abiltiy to detect any threat.
This theme has focus areas that are strongly linked to applications in defence and security, environmental monitoring and commerce, pushing new boundaries in sensing technology including revolutionary new antenna materials.
- Applied Electromagnetics
The Adelaide Applied Electromagnetics Group’s (AAEG) mission is to advance the fundamental research in electromagnetics, as critical enabling technology for progress in many other areas of electrical, electronic and optical engineering. On this path, its aims are to: produce world-class cutting-edge research on electromagnetic devices and interactions of electromagnetic fields with matter; educate the next generation of engineers and researchers in electromagnetics and generate graduates with corresponding relevant R&D skills; and provide innovative solutions to industry and high-technology companies through consulting and research projects. The goal of the group’s research is to create, based on unconventional material and geometries, novel devices with unique performance while keeping potential applications and manufacturability at the forefront. As a result, the group aims at experimentally validating all created designs and concepts. The output of the group has been steadily growing since its inception in 2008. The publication record of the three group leaders for 2012 includes 16 journal articles mostly in highly reputable journals and more than 20 conference publications in relevant conferences. The AAEG research leaders are regularly invited to present their research in international conferences and seminars..
Current research activities include:
- Metamaterials and plasmonics
- Wearable antennas and conductive textiles and polymers for RFID
- Reconfigurable antennas and frequency-selective surfaces
- Optical nano-structures inspired by radio-frequency devices
- Ultra-high-speed short-path communications
- Terahertz waveguides
Current research student opportunities:
- Surveillance and Remote Sensing
Radar is a key tool for remotely sensing and monitoring the environment and for the tracking and surveillance of both civil and military objects. The research team is focussed on developing optimum and adaptive signal processing algorithms for synthetic aperture, phased array and MIMO radars. Clutter mitigation is a key problem for just about all radars and research is actively focussed on developing techniques for reducing ground clutter for weather radars. GPS anti-jam technology is an active area of research and both the formulation and implementation of advanced array processing techniques for jammer localisation and rejection is also a major activity within the group.
The research team builds, operates and analyses the data from a number of different radars:
- Synthetic aperture radar and digital radar
- Remote sensing for soil moisture and biomass observations, bushfire observations, and precipitation observations
- Sensor array signal processing
- Locating interference and spoofers to Global Navigation Satellite Systems
- Malicious jamming detection with machine learning in wireless sensor networks
- Autonomous Systems
Autonomous systems are the next step in robotic technology that can interact independently with the complexities of the real world environment.
Our current autonomous systems research focus areas with defence applications include:
- Modelling intelligent agents with conditioned Markov processes
- Formation control of autonomous systems
- Reinforcement learning for multi-agent problems
- Autonomous light hybrid vehicles for defence applications and energy management
