Abstract: Doppler wind measurement lidar reverses the wind speed by the Doppler frequency shift of the echo signal of the system. In order to improve the detection accuracy of the wind field, the research was carried out from the aspect of frequency stabilization technology. During the frequency stabilization process, measures were taken to eliminate the long-term drift and short-term jitter of the laser frequency. For the long-term drift of the laser frequency, a temperature control box for the seed laser was designed and developed, which greatly reduced the long-term laser frequency shift by controlling the temperature of the water bath. The laser frequency was stabilized within ± 50 MHz. For short-term jitter of the laser frequency, a frequency stabilization system with an iodine molecular absorption cell as the core device was adopted to accurately control the temperature of the iodine molecular absorption cell through semiconductor temperature control, with a temperature control accuracy of 0.03 ℃, the frequency stabilization accuracy was improved, and the laser frequency was further stabilized within ± 8 MHz to meet the design accuracy requirements within ± 10 MHz. Through the establishment of Doppler wind measurement lidar system, the launching laser frequency stabilization device was verified. The observation results of 4 consecutive sets of wind field show that the detection height of the system was 17 km, and most of the variances were below 4 m/s. It meets the requirements of wind lidar measurement indicators.
