摘要
In order to solve the influence of atmospheric molecular signal on the echo signal of Mie-polarization lidar, a pure rotational Raman-Mie polarization lidar was designed for particle depolarization ratio measure. The echo signal and the SNR simulation results show that, the maximum detection distance can reach 12 km at night, verifying the feasibility of the system. The particle depolarization ratio profile was calculated by correcting the polarization signal with Raman signal. Comparing the depolarization ratio profiles in different weather conditions, it was found that this system was more suitable for the measurement of high altitude cirrus clouds and aerosol particles with smaller concentration but larger depolarization. © 2018, Editorial Department of Transaction of Beijing Institute of Technology.
