Acoustic System to Slew Chemical/Biological Sensor Point ofInterest

摘要

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 TimeDifference of Arrival (TDOA) algorithm. Developing a cueing mechanism for morepower intensive and range limited sensing CB techniques. Enabling the event detectionalgorithm to locate to a blast event using TDOA further information is provided of theevent as either Launch/Impact and further as either CB/HE. The point of interestinformation is gathered to give a viewing window to a range limited chemical sensingsystem that exploits spectroscopy to determine the contents of the chemical event. Thesensor suite is the system that will provide this information on the move while thechemical sensor will have adequate time to determine the contents of the event from asafe stand-off distance. The system exploits acoustic sensors to provide early detectionand identification of CB attacks at ranges exceeding 2500m. The integration of thesealgorithms with the TDOA algorithm provides a complex suite of algorithms that cangive early warning detection and highly reliable look direction from a great stand-offdistance for a moving vehicle to determine if a candidate blast event is of potential CBtype.
