Abstract
Paper presents a model of the all-fiber pulsed coherent Doppler lidar (IAO-lidar) build in the IAO SB RAS. Here is described lidar design, the algorithm for processing of lidar signals and the software-hardware system that implements signal processing in real time, created with the use of open source software. The results of joint measurements of the radial velocity by the IAO-lidar and the HALO Photonics (Stream Line) lidar are given.
Highlights
For experimental study of turbulent wind fields of the atmospheric boundary layer and coherent structures, including aircraft wake vortex, a pulsed coherent Doppler lidar (IAO-lidar) was recently build at the Institute of Atmospheric Optics (IAO) of the SB RAS
This paper presents design features of the IAO-lidar, algorithm for processing lidar signals, its implementation in real time, and comparative measurements of the radial velocity by IAO-lidar and by HALO Photonics (Stream Line) lidar
EXPERIMENT We carried out joint measurements of Signal-to-noise ratio (SNR) and wind velocity by the IAO-lidar and the commercial lidar “Stream Line” made by HALO Photonics
Summary
This paper presents design features of the IAO-lidar, algorithm for processing lidar signals, its implementation in real time, and comparative measurements of the radial velocity by IAO-lidar and by HALO Photonics (Stream Line) lidar
