大气风场的测量在环境、航空、航天等领域具有重要的应用价值。目前对于近距离大气风场的报道较少,而传统脉冲激光测风系统往往存在着低空盲区,不能满足对近距离低空风场的测量。采用连续激光光源设计并建立了一套短距测风系统,实现了近距离风场信息的测量,与测风仪对比同时刻实验测量结果误差不超过3%.对研制的连续激光测风系统结合适当的扫描方式进行组装,可以为短距风场的实际测量服务。 |

The measurement of atmospheric wind field has great practical application value in the fields of environment, aviation, aerospace and so on. At present, there are few reports about the short-range atmospheric wind field. Moreover, traditional pulse laser wind measurement system often has a low-altitude blind area,which can not satisfy the requirements of the measurement of short-range low-altitude wind field. A short-range wind measurement system was designed and set up to achieve close-range wind field information measurement based on a continuous laser light source. The error of the experimental measurement results compared with thate of the anemometer at the same time is are less than 3%. The developed continuous laser wind measurement system is assembled with appropriate scanning mode, which can serve for the actual measurement of short-range wind field. |
