Virtual Sensors Match Real-World Simulation Accuracy

Australian researchers have demonstrated that computer-generated "virtual sensors" can closely replicate the performance of real-world infrared camera systems.

Modelling and simulation holds potential for testing complex defence systems cost effectively using a combination of real-life and virtual testing. This validation step is critical in building confidence that modelling and simulation output replicates 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, a modelling and simulation environment developed by Aurizn 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 fidelity matters 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 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 continues to rise. Simulation is emerging as a possible solution, but only if it can be trusted, says Aurizn.

This research supports that physics-based simulation tools can closely match real-world sensor behaviour, providing confidence for their use in decision-making.
