Doppler wind measurement lidar system based on Fabry-Perot etalon was developed. The laser emission wavelength is 532 nm. The 300 mm diameter telescope is used to receive the echo signal， which can simultaneously detect the wind field from the boundary layer to the top of the troposphere in China. In order to improve the accuracy of Fabry-Perot etalon transmittance curve scanning， the three-channel Fabry-Perot etalon spectrum is directly scanned by pulsed light on the basis of strict installation and adjustment of the receiver optical path. The pulse signal is collected by high-speed acquisition card， and the accurate pulse signal intensity is obtained by fitting integration method. Using nonlinear least squares fitting method， the spectral widths of FPI-1， FPI-2 and FPI-L are 1.20 GHz， 1.22 GHz， and 1.18 GHz， respectively. The peak transmittance of FPI-1， FPI-2 and FPI-L is 0.817， 0.807， 0.768， respectively. The peak-to-peak spacing of FPI-1 and FPI-2 is 3.91 GHz and the peak-to-peak spacing of FPI-1 and FPI-L is 1.25 GHz. In the wind field observation test， the radial wind speed was measured multiple times in the same direction. 91% of the measurement variance was less than 4 m/s. In horizontal wind field observation， the system has a detection height of 13 km during the day and 17 km at night. Compared with the air balloon， the agreement is good from 2 km to 10 km.
