A Review of Progress and Applications of Pulsed Doppler Wind LiDARs [PDF]
Remote Sensing, 2019 Doppler wind LiDAR (Light Detection And Ranging) makes use of the principle of optical Doppler shift between the reference and backscattered radiations to measure radial velocities at distances up to several kilometers above the ground.

Pulse Accumulation Approach Based on Signal Phase Estimation for Doppler Wind Lidar [PDF]
SensorsCoherent Doppler wind lidar (CDWL) uses transmitted laser pulses to measure wind velocity distribution. However, the echo signal of CDWL is easily affected by atmospheric turbulence, which can decrease the signal-to-noise ratio (SNR) of lidar. To improve
