Abstract
A Scanning Rayleigh Doppler lidar for wind profiling based on a
non-polarized beam splitter cube optically contacted FPI is developed for
wind measurement from high troposphere to low stratosphere in 5-35 km.
Non-polarized beam splitter cube optically contacted to the FPI are used
for a stable optical receiver. Zero Doppler shift correction is used to
correct for laser or FPI frequency jitter and drift and the timing
sequence is designed. Stability of the receiver for Doppler shift
discrimination is validated by measuring the transmissions of FPI in
different days and analyzed the response functions. The maximal relative
wind deviation due to the stability of the optical receiver is about 4.1%
and the standard deviation of wind velocity is 1.6% due to the stability.
Wind measurement comparison experiments were carried out in Jiuquan
(39.741°N, 98.495°E), Gansu province of China in 2015, showing good
agreement with radiosonde result data. Continuous wind field observation
was performed from October 16th to November 12th and semi-continuous wind
field of 19 nights are presented.
