The Scattering Properties of Laser Beam Propagating in Lower Atmosphere at 1.55 um Wavelength

The atmosphere scattering properties of 1.55 μm laser beam is studied and analyzed in the background of the development of lidar. Mie and Rayleigh scattering are mainly considered to calculate the scattering parameters. Based on the theoretical models, performed numerical simulation to get the relationship between atmosphere scattering, temperature, pressure and refractive index of air. In cases of urban, rural and maritime aerosol model, the scattering parameters are given separately and their relationship with humidity is obtained.
