Key Points

To develop and evaluate a mobile, all-fiber 1.55-μm pulsed coherent Doppler LIDAR system capable of real-time long-range wind field monitoring.
Engineered an all-fiber LIDAR system featuring 100-μJ pulse energy at a 10 kHz repetition rate, an optical transceiver unit, a two-axis scanner, and a multicore digital signal processor for real-time processing.
Evaluated system performance during field campaigns by recording wind profiles and benchmarking against an anemometer.
Attained a horizontal detection range of 10 km with a temporal resolution of 1 s and a spatial range resolution of 30 m.
Achieved wind speed and wind direction correlation coefficients of 0.953 and 0.967, respectively, when compared against anemometer measurements.
Demonstrated system stability through continuous wind profile acquisition in the planetary boundary layer.
