Detectors, Environmental, Chemical Agent, Remote Sensing

Definition : Chemical agent environmental detectors designed for automated detection and identification of hazardous chemical agents (e.g., nerve and/or blister agents) using a sensor with long-range capabilities. These detectors typically consist of a passive, automated-scanning infrared sensor that can recognize agent clouds up to a line-of-sight range of 5 km (3 miles). Most systems work by comparing the background spectrum obtained by the detector with the information stored in a computer. Remote-sensing hazardous chemical detectors have a sensitivity in the order of 100 mg/cubic meter for nerve agents and 500 mg/cubic meter for blister agents; they are used in civil defense and military applications.
