Coherent Focused Lidars for Doppler Sensing of Aerosols and Wind [PDF]
Many coherent lidars are used today with aerosol targets for detailed studies of e.g., local wind speed and turbulence. Fibre-optic lidars operating near 1.5 μm dominate the wind energy market, with hundreds now installed worldwide.

Cloud Seeding Evidenced by Coherent Doppler Wind Lidar [PDF]
Evaluation of the cloud seeding effect is a challenge due to lack of directly physical observational evidence. In this study, an approach for directly observing the cloud seeding effect is proposed using a 1548 nm coherent Doppler wind lidar (CDWL ...

Pulse Accumulation Approach Based on Signal Phase Estimation for Doppler Wind Lidar [PDF]
Coherent 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
