多普勒风激光雷达在移动的环境中的操作对冲击和振动非常敏感，这可能导致严重的故障，例如光路的不对准和光学元件的损坏。为了能够稳定的激光雷达，并在运动中进行风场测量，减震和振动隔离系统的设计和实施。车载多普勒风激光雷达的性能在运动中进行了测试，首先在直径约为30米的圆形测试路线中，然后在常规高速公路交通中进行测试。在主振区，系统的隔振效率大于82%，冲击动挠度小于隔振器的最大挠度。在相同的移动的环境中的激光器锁定频率的稳定性也被发现在振动隔离系统安装之前和之后被大大提高。LIDAR数据分析的良好结果证实了隔振系统的可靠性，特别是视线速度和风廓线的平面位置指示器。
The operation of a Doppler wind LIDAR in a mobile environment is very sensitive to shocks and vibrations, which can cause critical failures such as misalignment of the optical path and damage to optical components. To be able to stabilize the LIDAR and to perform wind field measurements in motion, a shock absorption and vibration isolation system was designed and implemented. The performance of the vehicle-mounted Doppler wind LIDAR was tested in motion, first in a circular test route with a diameter of about 30 m and later in regular expressway traffic. The vibration isolation efficiency of the system was found to be higher than 82% in the main vibration area and shock dynamic deflection was smaller than maximal deflection of the isolator. The stability of the laser locking frequency in the same mobile environment before and after the vibration isolation system installation was also found to be greatly improved. The reliability of the vibration isolation system was confirmed by good results of the analysis of the LIDAR data, in particular the plane position indicator of the line of sight velocity and the wind profile.
