In the first part, the basic knowledge of particle scattering in meteorology and physics was introduced. the particles to be discussed include aerosol particles, fog droplets and raindrops and the em wave band in the discussion is near - infrared. in the second part, the mie theory was briefly reviewed and was applied to investigate the scattering characteristics of spherical atmospheric particles, the result shows that in the visibility measurement meter using forward - scattering method, when the working wavelegth is between 0. 8 m ~ 2 m, the scattering angle is between 25 ~ 40, the distinguishability and the relative scattering intensity would be better than those under other conditions. in the third part, the superellipsoid was used to describe a wide range of shapes such as spheres. ellipsoids and cylinders. an improved t - matrix method which can be used to calculate arbitry shaped particle ' s scattering field was introduced, and the scattering characteristics of non - spherical atmospheric particles was investigated with this method
計算結果表明，從相對散射強度、同一方向上不同粒子散射的可區分程度來看，在散射式能見度探測儀器中，工作波長介於0 . 86 m 2 m ，探測角度選取前向25度40度時，探測的結果將會是比較理想的。第三部分中，使用超橢球方程來統一描述各種非球形粒子的形狀，然後使用t矩陣方法計算了一些形狀的非球形粒子的近紅外散射特性。另外，在本文中還針對球形粒子的散射場提供了一種三維可視化方法，使對散射場強度的空間分佈的理解更加簡單，直觀。 -
