Paper Abstract

A study on the passive standoff detection and identification of Bacillus subtilis (BG) clouds with the Compact ATmospheric Sounding Interferometer (CATSI) sensor is presented. The analysis is based on recent spectral measurements of BG clouds obtained during the excursion phase of the Technology Readiness Evaluation trial held at Dugway Proving Ground, 15-26 July 2002. Good results from two trial episodes corresponding to the measurement of BG clouds at a distance of 3 km in a near-horizontal path scenario are used to explain and demonstrate the detection capability of the CATSI sensor. It has been found that the low thermal contrast (few tenths of a degree) between the BG cloud and the background yields weak but observable spectral signatures. The results of a series of simulations with the FASCODE transmission model have shown that the detection sensitivity for BG can be greatly improved for slant path scenarios.
