Laboratory assessment of thermal transmission in camouflage materials using the SR-5000N spectroradiometer

Recent domestic research on camouflage requires standardized evaluation methods and techniques to scientifically and reliably assess camouflage materials, such as fabrics and camouflage nets. This poses significant challenges due to the high level of confidentiality in the field and the limitations of experimental equipment. Drawing on several standards published by advanced nations, this study proposes a method for determining the thermal radiation transmission ratio through camouflage materials in a laboratory setting using the SR-5000N device. The proposed method offers several advantages, including rapid execution, accuracy, reliability, and broad spectral coverage, encompassing the two primary spectral regions of thermal camouflage: the mid-wave infrared (MWIR) and the long-wave infrared (LWIR) ranges. Independent field evaluations have validated the method’s effectiveness, demonstrating its practicality in saving time and resources for assessing the performance of thermal camouflage.
