We measured doppler signal by floating flours in the wind tunnel with Low-coherence Doppler lidar.An anemometer was set in the wind tunnel and compared with the particle velocity measured by Doppler lidar.The wind tunnel is installed at a position about 6 m away from the rider, and the wind direction is headwind with respect to the rider's line of sight.n both results, speed information of about 2.7 m / s was obtained, showing good agreement.In both results, speed information of about 2.7 m / s was obtained, good agreement.
