Abstract：It is of great significance to study the aerosol particles optical scattering properties in this band when using the infrared lidar to measure the atmospheric various components concentration. Especially the scattering coefficient and the backward scattering ratio of aerosol particles are important parameters for receiving scattering echo signal based on infrared lidar. It directly affects the precision and effective detection distance about the detection system. According to the Mie scattering theory， we can analyze the scattering efficiency factor and the scattering phase function of atmospheric aerosol particles. And we can accurately calculate the scattering coefficient and the backward scattering ratio of aerosol particles about different radius and different density. The simulation results show that with the increase of aerosol particles radius， the scattering efficiency factor is vibrations and the amplitude decreases gradually and finally it tends to near 2.04. On the condition of the constant wavelength， the backward scattering ratio of the atmospheric aerosol particles decreases with the increase of their radius.
