PROCEDURE FOR DETECTING WIND SPEEDS WITH A DOPPLE-LIDAR SYSTEM, IN PARTICULAR ONBOARD OF AIRCRAFT, AND DOPPLER-LIDAR SYSTEM.

摘要

Procedure to detect wind speeds with a Doppler-Lidar system (10), in which a laser beam of predetermined wavelength is emitted towards a spatial region (52a, 52b, 52c, 52d) and the back-diffused light is received from the spatial region, where to determine a Doppler shift, an interferogram (34) is created with an interferometer (16) and the interferogram intensity distribution is measured with a photodetector, characterized in that the intensity distribution is compared with a family of reference models, which have been previously determined for defined parameters, which comprise different densities and / or temperatures of the atmosphere, where from the comparison with the family of different reference models Doppler displacement is established as a measure of the wind speed.
