摘要

Direct-detection Doppler LIDAR has been demonstrated for its high temporal and spatial resolution in atmosphere wind detection from troposphere to stratosphere. As Doppler frequency is a relative value, the zero point drift would lead to wind velocity error. So the zero Doppler correction was necessary for high-accuracy wind measurement. We analyzed the reasons that would cause zero point drift and demonstrated a designed Fabry-Perot interferometer and front optics to measure Rayleigh scatter laser and emitted laser frequency in the meantime. Wind observation experiments were demonstrated in Xinjiang, China, and the measured wind profile coincided well with radiosonde results.
