Abstract
In order to accurately measure the 3-D real-time atmospheric wind field to cope with the problems of low-level wind shear during aircraft take-off and landing, a compact 3-D Doppler wind lidar was developed by using Doppler beam swinging (DBS) principle.The wind field data obtained by the lidar were compared with the anemometry data with the other standard equipments.It turned out that the effective measurement of atmospheric wind field was achieved by the lidar under both sunny and cloudy weather conditions.The root mean square errors of wind speed and wind direction were 0.42m/s and 5.33° respectively.The lidar, with high precision and good stability, plays an important role for wind shear warning, the forecast of low-level atmospheric wind field and wind field measurement of aircraft flight channel.关键词
