Abstract

Abstract: Based on MIE scattering theory,the radiative transfer model of absorption,emission and scattering particle system in space environment is established.The change of total radiation in smoke diffusion process is studied,and the infrared stealth effect of particle optical properties,particle number density and smoke thickness on the whole smoke shielding is analyzed.The results show that the medium wave can provide a better stealth effect,and can mask up to 90% of the vehicle radiation.The refractive index of particles has little effect on the smoke stealth effect,and the absorption index has a greater effect on the smoke stealth effect;the particle size has a greater impact on the stealth effect,and there is an optimal particle size selection under the specific optical properties.The density of smoke has a saturation value,when the saturation value is exceeded,the stealth effect will not increase,and the thickness of smoke screen has no obvious improvement on the stealth effect.

摘要： 基于MIE散射理论,建立太空环境下求解吸收、发射、散射性粒子系辐射传输模型,研究了烟幕扩散过程总辐射的变化,分析了粒子光学性质、粒径尺度、粒子数密度、烟幕厚度对整个烟幕遮蔽的红外隐身效果。结果表明:中波能起到较好的隐身效果,最多能遮蔽90%的飞行器辐射;粒子的折射指数对烟幕隐身效果影响较小,吸收指数对烟幕隐身效果影响较大;粒子尺度对隐身效果影响较大,在特定的光学性质下存在最佳粒径选择;烟幕的密度存在饱和值,超出饱和值后隐身效果不会增加;烟幕厚度对隐身效果没有明显改善。
