Modelling and simulation holds great potential in enabling complex defence systems to be tested cost effectively using a combination of real-life and virtual testing. This validation step is critical in building confidence that the output of modelling and simulation replicate real-world results.
The study, led by Dr Jonathan Hedger, Senior Research Scientist at Aurizn, has been published in the SAGE Journal of Defense Modeling and Simulation and validates the performance of Infinite Studio - Aurizn’s advanced modelling and simulation environment developed in collaboration with the Defence Science and Technology Group (DSTG).
By comparing laboratory measurements from real infrared cameras with simulated outputs in Infinite Studio, the research showed a high level of agreement between the two, in some cases with less than one percent difference.
This level of fidelity is critical as defence organisations increasingly rely on modelling and simulation to develop and test new capabilities.
The findings come at a time of heightened global instability, including conflicts in the Middle East and rising tensions across the Indo-Pacific.
These conditions are driving urgent demand for faster capability development, improved situational awareness, and more adaptable defence systems across Australia, the United States and allied nations.
At the same time, the cost and complexity of real-world testing - whether for aircraft, sensors or mission systems - continues to rise. Simulation is emerging as a key solution.
However, simulation is only useful if it can be trusted.
This research demonstrates that modern, physics-based simulation tools can closely match real-world sensor behaviour, providing the confidence needed to use them in critical decision-making.
