Early detection, warning, and reporting (DWR) of a CBRN incident are paramount in order to safeguard the life and health of the personnel and to sustain operational capability. The ability to rapidly detect, warn, and report such incidents equates to faster response times, reduced hazard exposure, and more efficient use of limited resources. It is hypothesized that fusion of CBRN sensor information at the tactical level will lead to earlier and more accurate detection, warning, and reporting of a CBRN incident than is the case with today’s DWR system. Integration of CBRN sensors in tactical networks could therefore be a triggering factor for significant improvement in operational performance with respect to response times and accuracy. The purpose of the project is to test the hypothesis that fusion of CBRN sensor information will lead to earlier and more accurate detection, warning, and reporting of a CBRN incident that has occurred.
