Paper Abstract

The IR smoke is a typical sort of aerosol. The radiation is covered by the smoke aerosol, which lead attenuate further more. This covering effect is obtained from the absorption and dispersion of the aerosol. The degree of the attenuation of the aerosol is determined by two important parts: the size and the component of the aerosol particulate system. According to the equation of the signal-noise-ratio of the IR system, the covering effect can be reflected by the spectral permeation rate. The attenuation of the aersol is composed of the absorption and the dispersion when the size of the smoke particular is as that of the radiation wavelength. The key issues to calculate the radiation are three factors: the radius, the density and the refraction rate of the smoke material. Another important part which influences the attenuation is the relative humidity of the atmosphere. A lot of factors, such as the Brown motion, the temperature diffuseness, the consistency diffuseness and the climate affect the formation and the distribution of the smoke aerosol.
