This report presents preliminary results on the polarised long-wave infrared passive standoff detection and identification of surface contaminants and cumulus clouds using different polarisation configurations. The capability of the Compact ATmospheric Sounding interferometer CATSI for detecting chemical warfare CW surface contaminants is demonstrated from measurements of the CW simulant SF96 on water. Some polarimetric measurements of cumulus clouds were also performed to demonstrate the capability of polarisation measurements. The results obtained with the polarimetric dual-beam interferometer indicate that the signal-to-clutter ratio may be significantly improved in the infrared remote sensing of surface contamination and hard target signatures.
