介绍了一套基于双边缘检测技术的1064 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±40m/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。
A set of 1064 nm Mie Doppler wind lidar based on double-edge detection technology is introduced. The Farbry-Perot etalon was used as a frequency detector to analyze the Doppler shift caused by atmospheric aerosols in the wind field. Receiver calibration is performed using a hard-target speed calibration system with a calibration accuracy of less than 1% over a radial speed of ± 40 m / s. The results of wind field measurement for eight consecutive days from April 23, 2006 are given.
