Моделирование 3.3 мкм дифференциальной абсорбцион- ной лидарной системы, используемой для дистанционного зондирования различных концентраций метана

The use of airborne remote sensing methods to determine methane concentrations on the ground has become an alternative to traditional on-site observation methods. However, the use of aircraft as a carrier of a lidar system is not always economically justified. In this paper, a modeling of 3.3 μm differential absorption lidar systems is carried out, the technical characteristics of which allow an unmanned aerial vehicle to be used as a carrier. The possibility of determining methane concentrations in a wide range (from 2 to 75 ppm) is shown, and optimal conditions for using such a system are determined
