Abstract

On the basis of analyzing exposed signature of amphibian armored vehicles, anti-jamming principle of dual infrared guidance and influence of water fog to infrared detection distance, the artificial water fog screening technique is put forward; and the relationship between spray quantity, water fog radius and extinction characteristics have been analyzed with Mie scattering theory which is used to choose the prime water fog radius to obtain best effect. Furthermore, a nicer performance of the water fog is proved by simulation calculation.

Key words: Amphibian armored vehicles, artificial water fog, dual infrared guidance, extinction section.
