Different from the existing methods for estimating averaged slant visibility by lidar and the traditional Koschmieder visibility formula, a measurement method for slant visibility is fundamentally proposed in this paper that considers the correction of slant path scattered radiance. Lidar is adopted to provide aerosol parameters, including optical depth and scattering parameters, and the SBDART (Santa Barbara DISORT Atmospheric Radiative Transfer) model is used to solve the radiative transfer equation to obtain the corresponding radiance distribution; thus, the corrected apparent brightness contrast between the object and background along the slant path is used to achieve accurate slant visibility. Based on the measurement principle of slant visibility, a theoretical simulation and an analysis of the slant path scattered radiance are performed, and the resulting slant visibility is studied in detail in this paper.

激光雷达和SBDART模型校正斜面可见度的方法

与现有的利用激光雷达估计平均倾斜可见度的方法和传统的Koschmieder可见性公式不同，本文从根本上提出了一种倾斜可见度的测量方法，该方法考虑了对倾斜路径散射辐射的校正。采用激光雷达提供气溶胶参数，包括光学深度和散射参数，并使用SBDART（圣巴巴拉DISORT大气辐射传递）模型求解辐射传递方程，以获得相应的辐射度分布；因此，校正后的物体和背景之间沿倾斜路径的视在亮度对比度可用于获得准确的倾斜可见性。根据倾斜可见度的测量原理，对倾斜路径的散射辐射进行了理论模拟和分析，
