英文摘要	The middle- and upper- atmosphere wind field are important parameters that characterize the middle- andupper-atmosphere environment, respectively. The detection of the middle- and the upper-atmosphere wind fieldare of great significance in the civil field and military field. Laser heterodyne spectroscopy technology is apassive remote sensing detection technology with high spectral resolution and sensitivity, and has developedrapidly in recent years. The laser heterodyne spectrometer that takes laser heterodyne spectroscopy technologyas its core, is developed due to its small size, light weight and stable structure. The verification of the ground-based wind field detection performance of the laser heterodyne spectrometer is a key part of its application tosatellites. In this paper, a wind speed simulation device is built in a laboratory environment to achieve a windspeed change from 0 m/s to 25 m/s in a wind field. A laser heterodyne spectrometer with a spectral resolutionof 0.003 cm-1 is used to measure the CH4 absorption spectrum without and with a wind field for different windspeeds, the resolution of measuring wind speed is 3 m/s. For relative and absolute calibration of the distributedfeedback laser (DL) frequency, an interference fiber with a free dispersion range D* = 0.01167 cm-1, awavemeter and a reference cell is used. The experimental results effectively verify the wind measurementperformance of the laser heterodyne spectrometer and prove the possibility of using the laser heterodynespectrometer to measure the atmospheric wind field
