Abstract : The artificial aerosol is widely used in the modern battlefields to protect the potential targets and to conceal the movement of personnel and materials. In this paper, the double-band infrared extinction coefficients of the artificial aerosol have been calculated and compared with the experimental data. The particulates were assumed to be small spheres and Mie's theory was employed with the grain size distribution function being lognormal. The numerical and the experimental results show that the size distribution and the materials of the particles are decisive of their infrared extinction capability. |
