A Novel Joint Denoising Strategy for Coherent Doppler Wind Lidar Signals

Remote Sensing
Coherent Doppler Wind Lidar (CDWL) is an effective tool for measuring the atmospheric wind field. However, CDWL is affected by various noises, which can reduce the usable value of the received echo signal.

Effects of Wind Turbulence on Coherent Doppler Lidar Performance

Journal of Atmospheric and Oceanic Technology, 1997
Abstract The effects of wind turbulence on pulsed coherent Doppler lidar performance are investigated theoretically and with computer simulations. The performance of velocity estimators is determined for the case of a single realization of a wind field described by a Kolmogorov spatial spectrum and for an ensemble average over many realizations.

Rapid Laser Ranging Method for Compact LiDAR Systems

Remote Sensing
We propose a rapid laser ranging method for compact LiDAR systems. It employs a high signal-to-noise ratio (SNR) coherent detection scheme to minimize the required measurement integration time, while also addressing key challenges encountered by existing
