Simulation of the infrared radiation characteristics of a vehicle model under sunny weather

Abstract

Military vehicles are vulnerable to hostile infrared reconnaissance in the battlefield. So, it is essential to investigate the infrared radiation characteristics and camouflage methods of the vehicle. This paper proposes a method utilizing heat exchange theory to study the temperature distribution and the infrared radiation characteristics of a simplified vehicle prototype. The research reveals that the temperature distribution and the infrared radiation distribution are different for all six surfaces, which are mainly influenced by internal heat source, air temperature and solar radiation. This study is expected to provide useful guidance to vehicle camouflage pattern design.
