This project aims to address the current challenges of developing practical multi-receiver passive radar systems, through the development of advanced receiver synchronisation techniques, which do not require the deployment of costly infrastructure. The project will develop novel algorithms and techniques that enable synchronous combining of data from multiple radars, allowing for the detection of smaller targets and significantly extending the radar coverage zone. The expected outcomes of this project include improved performance of passive radar systems and the advancement of radar technology. The benefits of this project include new applications in areas such as traffic monitoring, drone detection and national security.Read moreRead less
The Interplay of Feedback Control and Digital Communications. This project deals with two research topics in digital communications and control. The first is concerned with feedback communications for control systems, aiming to develop new design methods for network-based automation and control. The second studies new decoding and detection algorithms for digital communications.

The first is concerned with feedback communications for control systems, aiming to develop new design methods for network-based automation and control. The second studies new decoding and detection algorithms for digital communications. Applications of the proposed research work include network-based industrial control, wireless communication devices, and high density digital storage media. The cross-fertilisation of control systems and digital communications will help strengthen Australia's research expertise in the National Research Priority area "Information and Communications Technology" (ICT).

Locating Interference to GPS: Protecting the World's Aircraft Landing Systems. GRAS is an enormous initiative that is expected to generate billions of dollars in exports for Australia. The equipment developed in this project will protect the system from radio frequency interference. It thus protects these exports, and creates a new exportable product. By protecting this system, it makes air travel safer both in Australia and in the countries that buy this Australian technology.
Assisted GPS and Advanced Positioning For Emergency Services. Many volunteers have lost their lives fighting bushfires in Australia. Fires are becoming more numerous and more fierce. Some of those firemen could have been saved if better information was available: where they were, where the firefront was and how it was progressing. This project aims to save lives by solving part of this problem: locating and reporting the position of the remote firefighter by making GPS work reliably under trees. ....Assisted GPS and Advanced Positioning For Emergency Services. Many volunteers have lost their lives fighting bushfires in Australia. Fires are becoming more numerous and more fierce. Some of those firemen could have been saved if better information was available: where they were, where the firefront was and how it was progressing. This project aims to save lives by solving part of this problem: locating and reporting the position of the remote firefighter by making GPS work reliably under trees. This will also make search and rescue operations safer and more efficient. The technology can transfer readily into the location-based services market which is set to boom in the next decade. This project helps maintain momentum in Australia's world-class but small positioning industry.Read moreRead less
Human Muscle Stretch Reflexes: The Effects Of Stimulus Properties, Muscle State And Subject Intention

Summary
The best known muscle reflex is the tendon jerk, which is usually evoked by tapping the muscle tendon with a small hammer. This tap imposes a very rapid stretch on the muscle, which produces a stretch reflex. Different stretch responses, however, can be observed to slow or fast stretches, or to vibration of muscle. Normally, when the muscles of a relaxed person are stretched, no active response is observed. However, when the person is engaged in a task and contracting their muscles, then stretch ....The best known muscle reflex is the tendon jerk, which is usually evoked by tapping the muscle tendon with a small hammer. This tap imposes a very rapid stretch on the muscle, which produces a stretch reflex. Different stretch responses, however, can be observed to slow or fast stretches, or to vibration of muscle. Normally, when the muscles of a relaxed person are stretched, no active response is observed. However, when the person is engaged in a task and contracting their muscles, then stretch modulates the muscle activity such that an increase in contraction of the muscle opposes the stretch and defends the position of the joint against the external disturbance. This is the everyday situation in which stretch reflexes operate. Despite extensive investigation for over a hundred years, there is still no consensus among researchers about the behaviour of stretch reflexes nor about their role in the control of movement. Even the demarcation of reflex from voluntary muscle activity is not always certain. One of the outstanding features of stretch reflexes is the variability of their behaviour, which depends on the particular muscle involved, its level of contraction, the type of stretch and the task in which the person is engaged. This variability has made it difficult for researchers to determine the role of reflexes in the control of movement. In order to study stretch reflex behaviour in human subjects, we will measure the electrical activity of elbow muscles, the elbow position and the force generated at the joint under a variety of conditions. A series of five experiments will investigate specific unresolved issues such as the effect of subject intention on the modulation of muscle activity and how altered modulation of muscle activity may change the stiffness of our limbs. The objective of the experimental series is to fill in important gaps in the picture of the behaviour of the stretch reflex.Read moreRead less
A Positioning System for Mobile Phones. This project aims to produce a positioning system that integrates a mobile phone-based technique developed in Australia, known as Seekerzone, with GPS. The combination of Seekerzone and GPS delivers a system capable of reporting whether children or valuables are in a safe location.

As security becomes an increasing priority, this system can operate indoors or outdoors, and provides many solutions. Seekerzone has already attracted international interest, and coupled with GPS, its applications and export opportunities will multiply. The target product will provide effective and convenient security, while its developemnt will provide important research training in Australia's drastically under-resourced spatial industry.Read moreRead less
