A 1 064 nm Mie Doppler wind lidar system based on the double edge technique is described. The Fabry-Perot(FP) etalon is used as the frequency discriminator, which analyzes the Doppler frequency shift from the atmospheric aerosol movement by wind. The system frequency measurement is calibrated by the known line-of-sight (LOS) Doppler shift produced by a rotating disk, and the calibration accuracy in velocity is less than 1% in the range of ±40 m/s. The continuous field wind profiles in eight days are carried out from Apr. 23, 2006.
