Title: Feasibility of detecting chemical agents using a chemical imaging interferometer from low and high altitude platforms. Final report, August 1995-August 1996

Technical Report ·
OSTI ID:574933

The purpose of this study is to evaluate the feasibility of using a high scan speed Chemical Imaging FTIR System to passively detect chemical agent vapors from high speed airborne platforms. This evaluation was based strictly on radiometric calculations, and no attempt was made to factor in the degradation in signal to noise associated with detection/discrimination algorithms and preprocessing. Several agents were evaluated including GA, GB, GC, and HD at concentration-path length ranges from 0 to 25,000 mg/sq m. System performance was evaluated in terms of signal to noise as a function of altitude (300 km, 30 km, and 3 km) and spectral bandwidth (4 /cm, 6 /cm, 8 /cm, and 16 /cm). Performance was also evaluated for all of the primary absorption bands associated with each agent. Results indicate that acceptable performance (i.e., minimum detection levels as defined by military requirements) is obtained at altitudes of up to 300 km with reasonable aperture sizes (0.5 m or less).
