Abstract:
Firstly, the principle of laser radar, working system, the transmission characteristics, the use of Mie scattering theory to study pm2.5soot particles, dust particles and water mist scattering properties of the particles, the application Mieplot software to calculate aerosol particles scattering and absorption extinction cross section, combined with Lambert-Beer¡¯s law analysis of the impact of a single particle scattering on lidar, the paper is characterized by experimental platform, using a combination of theoretical and experimental approaches to verify the impact of the large number of aerosol particles scatter laser radar, innovation is the application of Lab VIEW software simulation platform to influence the scattering of laser radar, and finally get a large number of aerosol particles in the simulation concluded that lidar shorten the distance, measured target distortion, constant false alarm rate increased and other effects.
