Scientific paper

Passive standoff detection of chemical warfare (CW) agents is currently achieved by remote sensing infrared spectrometry in the 8 - 12 micrometer atmospheric window with the aid of automatic spectral analysis algorithms. Introducing an imaging capability would allow for rapid wide-area reconnaissance and mapping of vapor clouds, as well as reduce false alarms by exploiting the added spatial information. This paper contains an overview of the CW agent standoff detection problem and the challenges associated with developing imaging LWIR hyperspectral sensors for the detection and quantification of vapor clouds, as well as a discussion of spectral processing techniques which can be used to exploit the added data dimensionality.
