| 摘 要： | 激光遥测大气消光系数分布的主要方法,是假设大气消光系数与大气体后向散射微分截面之比值k为常数,并取激光实测的地面值,然后由解光雷达方程求得。本文将讨论由于大气气溶胶物理属性随高度变化以及大气分子散射的作用,使比值k产生相应变化,并分析由此引起大气消光系数的探测误差。

| Abstract: | The assumption of a constant ratio k of atmospheric extinction coefficient to atmospheric volume backscattering differential cross section in laser remote measurement is not always valid due to the variations of properties of atmospheric aerosols and atmospheric molecular scattering. In this paper the change of k and its resulted errors in measurement of atmospheric extinction coefficient distribution are discussed. |
