Abstract
The Defence Science and Technology Organization (DSTO) of Australia is currently considering the implementation of a commercial-off-the-shelf (COTS) software package called SensorVisionTM to fulfil the scene generation function of an infrared (IR) hardware-in-the-loop (HIL) system. Before the software can be used in the intended application, there is a need to verify and validate the SensorVision models to ensure that the generated scenes are sufficiently realistic for HIL simulation purposes. This paper reports a section of work pertaining to the validation of the temperature prediction models employed by SensorVision. Predicted diurnal temperature profiles of air and a concrete sample are compared against experimental data collected from a location in northern Australia. It is shown that these models generate results that are inaccurate for the location considered. The errors are attributed to the inability of the code to allow users to define atmospheric profiles customized to geo-specific locations. However, reasonable agreement between predicted and measured concrete surface temperatures were obtained empirically by manipulating the heat transfer parameters associated with the concrete sample.
