In light of the challenges posed by the requirement of numerous parameters calibration, the involvement of multiple metrology specialties, and the inadequacies in existing calibration methods for coherent Doppler wind lidar. Considering the characteristics of laser wind measurement, such as non?contact, high spatiotemporal resolution and large detection range, the method of "feature analysis and multi?method integration" is adopted to break through the difficulties of quantitative evaluation of controversial parameters such as wind speed, wind direction, maximum measurement distance and detection blind zone. The advantages, disadvantages and applicable conditions of three different wind speed calibration methods, namely the wind speed calibrations using a calibration turntable, the radio frequency signal simulation of Doppler frequency shift and using a standard anemometer, are analyzed. Moreover, the calibration turntable wind speed calibration method was improved to enhance the data reliability of the wind speed parameter calibration. Aiming at the difficult problem of wind direction calibration, the calibration method under different scanning modes is presented dialectically to improve its universality. Based on specific measurement cases, the calibration results of wind speed and wind direction are given, and the uncertainty analysis of wind speed and wind direction parameters are performed, effectively illustrating the feasibility of the calibration method. The research results provide standardized technical support for the precise detection of wind fields in such fields as meteorological observation, aviation safety, and new energy, and have positive significance for promoting the development of atmospheric remote sensing metrology technology.
