Research Topics


The proposed system will allow tracking the movement of chemical clouds in real time from a safe standoff distance. The instruments used are passive standoff chemical agent detectors already fielded (M21). Each instrument individually can only measure the total of all the chemical in its line-of-site; the distance to the cloud is unknown. By merging data from multiple vantage points (either one instrument moving past the cloud or two or more instruments spaced so as to view the cloud from different directions) a map of the cloud location can be generated. The equipment required for the proposed system is either government-off-the-shelf or commerically available. Also, the data fusion techniques (tomography) have been demonstrated previously in the medical field. The proposed system represents a low risk solution to the problem of remotely tracking toxic and hazardous chemical clouds. BENEFITS: The Chemical Tracking System would be able to monitor the movement of many chemical clouds of either military or industrial origin. Since the technique is standoff, the personnel are not exposed to toxic hazards while they follow the cloud. Also the equipment works on-the-move which allows rapid response to emergency situations (plant explosion, tank car accident, chemical terrorism).
