摘    要:针对成像激光雷达的应用背景,利用Klett迭代方法求解水平路程激光大气传播的消光系数,并采用Monte-Carlo方法对典型应用背景下的接收信号进行了模拟,结果表明:采用该方法求解的消光系数的理论误差小于6%;在考虑大气湍流起伏的情况下,消光系数的起伏变化明显,但是与理论模型的变化趋势吻合。

关 键 词:激光雷达  气溶胶  大气消光系数

Abstract:The atmosphere extinction coefficient for the application of imaging laser radar is solved by Klett iteration method. The Monte-Carlo simulated results for typical conditions of the imaging laser radar operation show that the theoretical error of the extinction coefficient is less than 6%. The fluctuation of the extinction coefficient affected by the atmospheric scintillation is obvious, but the variation trend is coincident with the theoretical model.
Keywords:Lidar  Aerosol  Atmospheric extinction coefficient
