Abstract
Impulse wind lidar (IWL) signal processing software developed by JSC «BANS» recovers full wind speed vector by radial projections and provides wind parameters information up to 2 km distance. Increasing accuracy and speed of wind parameters calculation signal processing technics have been studied in this research. Measurements results of IWL and continuous scanning lidar were compared. Also, IWL data processing modeling results have been analyzed.
Highlights
An effective means for determining the wind profile of the surface layer of the atmosphere is a Doppler wind lidar
The most widely spread lidars are operating with infrared laser beam at a wavelength of 1.54 microns
VAD and DBS are the atmosphere scanning modes by the lidar laser beam. They provide aggregated data reception on the values of the radial projection of the wind speed in the measurement direction. This data is further converted into the value of the full vector of wind speed for all heights of scanning [1]
Summary
An effective means for determining the wind profile of the surface layer of the atmosphere is a Doppler wind lidar. The lidar beam is scattered by aerosol particles which are present in the atmosphere. VAD and DBS are the atmosphere scanning modes by the lidar laser beam. They provide aggregated data reception on the values of the radial projection of the wind speed in the measurement direction. This data is further converted into the value of the full vector of wind speed for all heights of scanning [1]
