脉冲多普勒激光雷达是远距离、高分辨率测量径向风速的有力工具。随着商用多普勒激光雷达的发展和采购成本的降低，双多普勒激光雷达系统在未来几年将越来越容易获得。本研究回顾了最常见的双多普勒技术，描述了一个高度同步的远程双多普勒激光雷达系统的设置，并广泛讨论了与这种复杂的测量技术的不同种类的错误。通过检索算法，包括单多普勒激光雷达的误差和发生的各种参数，如相对光束角度，时间和空间尺度的扫描模式，和大气条件的组合的仪器的误差和它们之间的相互作用的来源进行跟踪。
AbstractPulsed Doppler lidars are powerful tools for long-range, high-resolution measurements of radial wind velocities. With the development of commercial Doppler lidars and the reduction of acquisition costs, dual-Doppler lidar systems will be become increasingly accessible in upcoming years. This study reviews the most common dual-Doppler techniques, describes the setup of a highly synchronized long-range dual-Doppler lidar system, and discusses extensively the different kinds of errors connected with this complex measurement technique. Sources of errors and their interactions are traced through the retrieval algorithm, including errors from single-Doppler lidar and those occurring from a combination of instruments related to various parameters, such as relative beam angles, time and spatial scales of the scan pattern, and atmospheric conditions.
