AbstractA 1.54 μm eye-safe all-fiber pulsed coherent Doppler lidar (CDL) system is developed to measure wind profiles. The laser is operated with 300μJ pulse energy and pulse width of almost 500 ns and pulse repetition rate of 10 kHz. The diameter of optical telescope is 100 mm. Spectra of 10k pulses are accumulated to increase the SNR of the signal for retrieving the Doppler shift of the light of sight (LOS) wind speeds. The profiles of wind vector are retrieved less than 20 seconds. Field experiments are implemented to validate the CDL performance. Good agreement is shown between the CDL and the balloon results with wind speed and direction errors of 0.73m/s and 5.2°. Airborne wind lidar experiments are also successfully carried out in 2015.
