This paper presents a fusion process developed for the Future Armoured Vehicle System (FAVS) Technical Demonstration (TD) project [1]. One of the project objectives was to develop, optimize and demonstrate a multi-sensor suite mounted on an army vehicle to detect and identify targets while the platform was moving. The sensors consisted of a cooled infrared camera, millimetre-wave radar and a defensive aide suite. For the purpose of this paper, only the first two sensors were considered in the fusion study. This paper presents the sensor suite, the fusion process, a description of a field trial used to gather target detection data, and the results and analysis of the fusion process.
