Direct detection Doppler Wind Lidar With twin-channel Fabry-Perot interferometer

本文明确了全球大气风场观测的重要性,较为详细地介绍了测风的基本原理、基于双Fabry-Perot标准具的双边缘测风激光雷达的系统结构和技术参数。明确了测风系统回波数据的处理方法及风速测量的误差计算。该风速反演方法和误差估算方法的可行性已经被实验验证。

The importance of global wind measurement is presented. The measured principle of Doppler wind lidar based on twin-Zehannel Fabry-perot etalon was developed to detect wind field. The principle of wind detection, overall structure of the lidar and the technique parameters were introduced. The corresponding data processing methods were shown and the measured errors of wind speed were simulated and analyzed. Results indicate that the improved method was feasible.
