Wind Fied Data Retrieval and Accuracy Optimization for Coherent LiDAR

In the background of the urgent need of the wind power industry, the laser test wind radar is based on high precision, remote, anti-interference and easy to deploy, and gradually becomes the real-time measuring wind tool widely used in the design, operation and optimization of wind power. The laser radar is measured by measuring the scattering signal after the aerosol of the air movement. In order to further improve the accuracy of wind speed and obtain high and reliable wind field data, this paper focuses on the method of the wind field data and the method of data quality control to improve the accuracy of the wind. The laser test of the data quality control is certified by the third party authority, the correlation coefficient is 0.993, measuring the wind speed deviation is less than 0.1 m/s, which reaches the advanced level of the industry.
