Doppler wind lidar can obtain three-dimensional wind field information with high temporal and spatial resolution in clear and clean atmosphere. In order to verify the detection accuracy of the WINDLE LIDAR coherent Doppler wind lidar developed by Beijing Research Institute of Telemetry, from April to May, 2020, the lidar and L-band sounding radar were used for synchronous comparative observation at the Southern Suburb Observation of Beijing.From June to July, 2022, this lidar is compared with WINDLE U7 lidar of Beijing Research Institute of Telemetry at the same site.Through the correlation analysis of the data, the comparison results are as follows：1）The vertical detection distance is greater than 5 km and the maximum detection height is 8.5 km. 2）Compared with L-band sounding radar, the total correlation coefficients of wind speed and direction data fitting are 0.990 and 0.998 respectively. The system deviation and standard deviation of the overall wind speed and direction are 0.114 m/s and 3.078°, 0.489 m/s and 3.969° respectively, which have good consistency. 3）Compared with WINDLE U7, the total correlation coefficients of wind speed and direction data fitting are 0.999 and 0.999. The system deviation and standard deviation of the overall wind speed and direction are 0.209 m/s and 1.077°, 0.255 m/s and 1.220° respectively. The superiority of the lidar system can be seen.
