Coherent Doppler lidar provide important data for investigating turbulent transport and exchange processes in the lower troposphere with high vertical and time resolution.. TIT (Tohoku Institute of Technology) and CRL(Communication Research Laboratories) have been developing the 2-μm in coherent lidar system. In this paper, we discuss the conceptual design of lidar system and also the algorithm for data analysis in order to visualize wind data. current status of our coherent Doppler lidar.
