Abstract: A portable coherent lidar system has been developed, which has the advantages of compact structure, small volume, lightweight, and high degree of automation. The overall weight of the system is no more than 15 kg, and the lidar can work using only a battery. The system adopts a fast frequency processing algorithm to improve the processing speed of the Doppler frequency shift, and compared with the traditional processing methods, the processing time of radial wind speed of this system is reduced by three times. The performance of the system has been validated in field experiment, and it shows that the detection height of the system reaches 1.5 km and the detection range of wind speed is 0-50 m/s.

Key words: coherent lidar, Doppler frequency, wind, boundary layer
