THERMOPHYSICS OF RADIATION HEAT EXCHANGE FOR THERMAL MASKING

Abstract

This paper analyzes modern thermal masking methods. These methods are used to prevent detection of heated objects using thermal imaging cameras and other similar devices. These methods are particularly important during combat operations to conceal personnel and military equipment. It is shown that the main areas of thermal masking technology development are related to methods for reducing the surface temperature of a heated object and decreasing its emissivity. These measures reduce the intensity of infrared radiation detected by a thermal imager. It is noted that the most effective solution to these problems is the creation of low emissivity surfaces in atmospheric windows and selective emission in other electromagnetic wave ranges for thermal monitoring and surface temperature reduction.
