A cross-correlation analysis of lidar echoes from an artificial tracer transported through two closely spaced atmospheric scattering volumes provides a remote measurement of the wind speed along the line joining the two volumes. A pulsed nitrogen transit-time lidar has been developed and used to make these measurements in real-time intervals of approximately 4 sec. The wind speed measurements are compared with conventional anemometer data. An extension of this technique to natural aerosol concentrations that exploits the laser wavelength dependence of the system SNR is discussed.
对通过两个紧密间隔的大气散射体传输的人工示踪剂的激光雷达回波进行互相关分析，可以远程测量沿连接这两个散射体的直线方向的风速。已经开发出一种脉冲氮渡越时间激光雷达，并用于以大约4秒的实时间隔进行这些测量。将风速测量结果与传统风速计数据进行了比较。讨论了该技术对自然气溶胶浓度的扩展，该扩展利用了系统信噪比与激光波长的相关性。
