Abstract
The DRDC Valcartier Spectral Imagery Laboratory currently supports hyperspectral imagers designed for field measurements. The ground-based Passive Infrared Ranging And Target Evaluation System (PIRATES) has been used over the years for the infrared signature characterization of different kinds of military related targets. This report highlights some issues observed in recent long range missile IR detection results, such as large negative features in the calibrated spectra. The bulk of these negative features are found to be related to instrument self-emission. Two algorithms are proposed to eliminate these features. The remaining negative peaks were the result of source instability, and appear principally in the peripheral region of the missile plume. Solutions are proposed to limit these negative features, such as tracking the missiles as smoothly as possible. The algorithms and solutions proposed will allow for the extraction of more accurate information from the original data.
