Abstract

Integrating a sensor suite with ability to discriminate potential Chemical/Biological (CB) events from high-explosive (HE) events employing an acoustic sensor array with a Time Difference of Arrival (TDOA) algorithm. Developing a cueing mechanism for more power intensive and range limited sensing CB techniques. Enabling the event detection algorithm to locate to a blast event using TDOA further information is provided of the event as either Launch/Impact and further as either CB/HE. The point of interest information is gathered to give a viewing window to a range limited chemical sensing system that exploits spectroscopy to determine the contents of the chemical event. The sensor suite is the system that will provide this information on the move while the chemical sensor will have adequate time to determine the contents of the event from a safe stand-off distance. The system exploits acoustic sensors to provide early detection and identification of CB attacks at ranges exceeding 2500m. The integration of these algorithms with the TDOA algorithm provides a complex suite of algorithms that can give early warning detection and highly reliable look direction from a great stand-off distance for a moving vehicle to determine if a candidate blast event is of potential CB type.
