摘要

An iterative method for determining slope in noisy lidar data is considered based on the use of a corrected ("shaped") inverted function and an assumed behavior of the unknown function of interest (an "image function"). The method is utilized for extracting extinction-coefficient profiles from data of multiangle measurements. The sequence and specifics of the retrieval procedure, results of simulations, and essentials of the practical retrieval of particulate extinction-coefficient profiles from signals of the elastic scanning lidar are considered. The methodology may be applicable when extracting the extinction-coefficient profiles from an elastic lidar operating in a multiangle scanning mode, a combined Raman elastic-backscatter lidar, or a high spectral resolution lidar operating in a fixed angular position.
