Low tropospheric wind profile from a 1.06 μm Doppler lidar
摘要
介绍了一套基于双边缘检测技术的1 064 nm Mie多普勒测风激光雷达系统.采用Farbry-Perot标准具作为频率检测器,分析了风场中大气气溶胶运动造成的多普勒频移.利用转盘硬目标的速度校准系统对接收机校准,在±40 m/s的径向速度范围内,校准精度小于1%.给出了从2006年4月23日起连续八天的风场测量结果.
Abstract
A 1 064 nm Mie Doppler wind lidar system based on the double edge technique is described. The Fabry-Perot(FP) etalon is used as the frequency discriminator, which analyzes the Doppler frequency shift from the atmospheric aerosol movement by wind. The system frequency measurement is calibrated by the known line-of-sight (LOS) Doppler shift produced by a rotating disk, and the calibration accuracy in velocity is less than 1% in the range of ±40 m/s. The continuous field wind profiles in eight days are carried out from Apr. 23, 2006.
