A Hybrid Genetic/Powell Algorithm for Wind Measurement in Doppler Lidar [PDF]
Photonics, 2022 Doppler peaks extraction from massive raw data is a tricky part of coherent Doppler wind Lidar (CDWL) optimization. In this paper, a hybrid genetic/Powell algorithm (HGAP) is proposed to process the power spectrum of the measured signal from CDWL.

Wind turbulence estimates in a valley by coherent Doppler lidar [PDF]
Meteorological Applications, 2011 AbstractIn this paper, the effect of several turbulence parameters during various flow conditions in Owens Valley, educed from coherent Doppler lidar data have been studied. Radial velocity structure functions are processed to estimate the turbulent kinetic energy (TKE) dissipation rate, integral length scale and velocity variance, assuming a ...

Wind Coherence Measurement by a Single Pulsed Doppler Wind Lidar
Energy Procedia, 2016 AbstractA single pulsed Doppler wind lidar, deployed at the FINO1 platform in the North Sea, has been used to monitor the lateral and vertical coherence of the along-wind component. To maximize the sampling frequency of the monitoring system, a particular configuration based on small sweeping angles around the mean wind direction is used.
