摘要: 在进行实际风速测量之前,对于新研制的测风激光雷达系统进行校准,可以验证并提高风速测量的准确性。根据瑞利散射多普勒激光雷达的测量原理,提出了利用瑞利散射谱和米散射谱之间的关系,采用运动硬目标实现对瑞利散射多普勒测风激光雷达进行校准的方法。设计了对瑞利散射多普勒测风激光雷达进行校准的实验系统,并给出了详细的校准步骤。

Abstract: Before making wind measurements, it is vital to calibrate the new developed Doppler wind lidar system, which can demonstrate and improve the validity of the lidar system. Based on the principle of wind measurement, a new method for the calibration of Rayleigh Doppler wind lidar taking advantage of the relationship between Rayleigh scattering spectrum and Mie scattering spectrum is proposed. This method uses a moving hard target to calibrate the Rayleigh Doppler wind lidar. The experimental system is designed for Rayleigh Doppler lidar calibration and the detailed processes are given as well.-
