| 摘 要： | 为了对激光测风雷达在民用机场的运行环境适应性及综合保障能力进行评估，采用国产自研激光测风雷达在典型高原机场为期3个月的风场联合监测试验数据，结合同址相关气象资料，分晴、多云、阴、雾及降水等不同气象条件，对激光测风雷达的风场数据进行了分析，以揭示典型高原机场的风场特征，检验国产激光测风雷达的综合保障能力。结果表明，在不同天气类型下，激光雷达的测风性能存在明显的差异，其在晴、多云、阴天整体表现较优，水平最大探测距离最远可达6623m，垂直最高可达2895m；同时，激光测风雷达能精准捕捉到高原机场的风场在时间尺度和空间尺度上的典型变化特征。该研究为雷达在民航的应用提供了参考。

Analysis of the wind field characteristics using the wind lidar in a typical plateau airport |
| |
| Abstract: | In order to evaluate the operational environment adaptability and comprehensive support capability of lidar in civil airport, experimental data was monitored in a typical plateau airport by using a wind lidar which is made in China. By considering the factors such as historical weather data in the same place, the weather condition of sunny, cloudy, overcast, fog and rainy days, the lidar's wind data was analyzed, and then the typical wind feature in a plateau airport was revealed. The comprehensive support capability of a wind lidar was also tested at the same time. The results show that, lidar's performance of catching wind field is different under different weather condition. In sunny, cloudy, and overcast days, its performance is better, and its horizontal and vertical sounding range is up to 6623m and 2895m, respectively. Moreover, the lidar can accurately discover the wind field's typical feature that is changeable in timing and spacing. This study provides a reference for the application of radar in civil aviation. |
