本文简要介绍了青岛海洋大学海洋遥感实验室研制的以碘滤波器为接收鉴频器的陆基移动非相干多普勒风激光雷达系统。本文所提供的2000年10月和11月风廓线的结果是由Mie和Rayleigh后向散射联合获得的，这是我们所知的第一个由这种系统进行对流层风测量的报告，在对流层中也可以进行所需的气溶胶散射比的独立测量。第二个碘蒸气过滤器用于将激光锁定在风和气溶胶散射比测量的绝对频率参考上。利用导汽球进行了激光雷达风廓线测量的比对实验。结果表明：2 ~ 4 km海拔范围内风速和风向标准差分别为0.985 m/s和17.9°；
This paper briefly discusses the mobile ground-based incoherent Doppler wind lidar system, with iodine filters as receiving frequency discriminators, developed by the Ocean Remote Sensing Laboratory, Ocean University of Qingdao, China. The presented result of wind profiles in October and November 2000, retrieved from the combined Mie and Rayleigh backscattering, is the first report to our knowledge of wind measurements in the troposphere by such a system, where the required independent measurement of aerosol-scattering ratio can also be performed. A second iodine vapor filter was used to lock the laser to absolute frequency reference for both wind and aerosol-scattering ratio measurements. Intercomparison experiments of the lidar wind profile measurements were performed with pilot balloons. Results showed that the standard deviation of wind speed and wind direction, for the 2-4 km altitude range, were 0.985 m/s and 17.9 degrees, respectively.
