Description

technical field

[0001] The invention relates to a laser radar multi-channel photon counting and analog detection device and method, which belongs to the technical field of high-speed real-time acquisition and processing of laser radar signals, and is used to realize photon counting detection and analog detection of atmospheric detection laser radar multi-channel echo signals. Background technique

[0002] Atmospheric aerosols and clouds play an important role in the process of global climate and environmental changes, and have an important impact on the radiation budget between the earth-atmosphere-ocean, and have attracted widespread attention from the scientific community and the international community in recent years. Traditional measurement methods are difficult to obtain high-resolution vertical distribution of atmospheric aerosol characteristics in real time. Atmospheric detection lidar is a powerful tool for detecting the vertical distribution of atmospheric aerosols ...
