General Description
The Joint Service Lightweight Standoff Chemical Agent Detector developed and produced by General Dynamics Armament and Technical Products provides ground platforms of the 21st century with state-of-the-art remote chemical agent detection. The unit uses a passive infrared detection system that automatically searches the 7- to 14-micron region of the surrounding atmosphere for chemical agent vapor clouds. Using sophisticated pattern recognition algorithms, JSLSCAD detects, classifies and identifies chemical agents while discriminating against both natural and manmade battlespace interferents. Once detection is made, JSLSCAD identifies the agent cloud and alerts operators with audible and/or visual alarms. It also indicates the direction and extent of the agent cloud on a graphical computer display and forwards the Nuclear, Biological and Chemical report details through the Joint Warning and Reporting Network. The JSLSCAD is the first chemical detection system to furnish 360-degree coverage for ground platforms for a detection range of up to 2 kilometers, allowing personnel to avoid contaminated areas or don protective masks and clothing. The JSLSCAD is currently in full rate production and is fielded on the Stryker-NBCRV (Nuclear Biological Chemical Reconnaissance Vehicle).
Technical Description
The JSLSCAD uses a passive Fourier Transform Infrared (FTIR) technology to allow detection of Chemical Warfare Agents (CWA) and Toxic Industrial Chemicals (TIC) at standoff distances.
