Wind measurement accuracy with incoherent Doppler lidar using an iodine vapor filter

摘要

The incoherent Doppler lidar technique using the frequency doubled Nd:YAG laser which was alternately tuned to the both slopes of one absorption line of the molecular iodine was developed and wind measurements were observed from 8 to 25km with 500m range resolution. Owing to the evaluation of measurement accuracy of this Doppler lidar, the truth of the zero wind is confirmed by using the direct reflection light from the hard target and the standard deviation is 0.35m/s. The comparison observations between the lidar wind velocities and the wind profiles of a wind profiler are performed experimentally.
