Title:
LASER RADAR DEVICE AND METHOD FOR DETECTING SPEED OF MEASURED OBJECT
Document Type and Number:
WIPO Patent Application WO/2014/041852
Kind Code:
A1
Abstract:
A speed detection unit (16) selects a speed calculation method corresponding to an SNR peak value detected by a peak SNR detection unit (15) from a plurality of speed calculation methods for calculating the speed (wind speed) of an aerosol, and calculates the speed (wind speed) of the aerosol in accordance with the selected speed calculation method. By this configuration, the effect is obtained whereby the speed (wind speed) of an aerosol can be calculated with high precision in a short time.
