Description

technical field

[0001] The invention relates to a semiconductor laser-based laser radar for detecting the space position and time evolution of the atmosphere itself and tiny particles (including aerosol and cloud) in the atmosphere. Background technique

[0002] Compared with other remote sensing technologies, lidar has unique advantages such as high detection accuracy, good temporal and spatial resolution, light weight and small size, and has great application potential in remote sensing detection of the atmosphere, ocean and land. Among the various atmospheric detection lidars, the meter scattering lidar, which is used to detect the spatial distribution and temporal variation of low-altitude atmospheric particles (including aerosols and clouds), is relatively simple and practical, and has been widely used in meteorology, Environmental protection, traffic safety, range support, atmospheric science research and many military fields. But the reality is that the demand for th...
