Analysis of the Thermal Shielding Properties of Camouflage Materials

摘要

In a previous paper, we discussed our techniques for measuring the thermal shielding of materials. Two heated panels served as surrogates for heated vehicle components, such as armor heated by the engine. The outer surface of each panel was thermostatically controlled to the same temperature. The camouflage material covered one of the panels, while the other, uncovered, panel acted as the baseline. Periodically, we collected calibrated infrared images of the two panels at 3 to 5 and 8 to 12 microns. In this paper, we present techniques to analyze further data from these measurements. The goal of the analysis is to quantify the relative capability of materials to shield from view warm vehicle components. We also present results of a simple experiment to measure the effect of air movement on the shielding properties of the materials.
