Paper Abstract

The 1064nm Doppler wind lidar with a dual Fabry-Perot etalon based on the edge technique has been developed to measure wind profile in the troposphere. The construction of the lidar system is described in the paper. The dual etalon with high-spectral resolution are used to discriminate the Doppler shift from the aerosol backscattering. The accuracy of the lidar system is analyzed and discussed especially for the etalon parameters. The transmittance curve of the etalon is measured and the results show that the standard deviation of the transmittance will cause the velocity error of 0.5m/s. The lidar system is estimated to measure the wind speed up to 10km with the accuracy of less than 2m/s. The preliminary result of the radial velocity measurements has been obtained.
