Mie wind lidar receiver based on Fabry-Perot etalon

The principle of Doppler wind lidar based on Mie backscattering was introduced. The wind lidar was composed of transmitting system, receiving system, transceiving system and controlling system. The most important of these systems is receiving system which was usd for a frequency discriminator. The parameters of Fabry-perot etalon were designed while the wind measures error was least and the mechanical technics can be realized. The structure of Mie Doppler wind lidar receiver was designed. The transmittance of etalon was measured and the parameters of etalon were fitted by Pseudo-Voigt function. The difference between the measured etalons parameters and designed parameters was lower than 5%. This receiver be used for the wind lidar system and the horizon wind velocity and direction were obtained. The result of wind profile measured by the system is in accordance with the wind profile measured by Airda16000 approximately.
