Abstract

A software developped in C language for a quick field calibration of thermal imagers is presented. The software allows to take into account the atmospheric transmission between the target and the imager, and to evaluate the corrected blackbody radiation temperature of any resolved area on the target at a known range. The software and the field procedure for calibration are described. Some validation tests carried out during the NATO RSG-17 trial in Meppen Germany, and more extensive tests performed at DREV after the trial are also presented. The error budget in calibrating thermal imagers and evaluating both extended and point target signatures from thermal imagery is analysed and discussed.
