Application of Laser Radar in Atmosphere Environment Monitoring

laser radar is a kind of modern active optical remote sensing device and is the outcome of the combination of the traditional radar technology and the modern laser technology. It takes laser as the light source and senses remotely the target through the radiation signal generated when the detecting laser and the target interact. This paper summarizes the structure and classification of the laser radar for the purpose of atmosphere composition detection, and also discusses the existing problems and development trends.
