If a threat substance is detected in elevated amounts, information about the type, location, time and amount will be registered and sent to a command centre where further evaluation and appropriate actions is performed. The intention is first to cover a large area that will be reduced step by step to smaller areas. The search strategy in the smaller area is to increase the number of sensors used in order to localise the bomb factory. The exact pinpointing of the bomb factory will be performed using stand-off detectors in mobile equipped units.
The basis for the system is the continuous on-line analyses of traces of explosives and precursors in vapour phase and sewage over a significant area of cities. The data from the networked sensors will be fused and sent to a command centre for evaluation. The final verification is stand-off trace detection with equipped mobile units for pin-pointing the bomb factory.
