Laser coherent detection technology can obtain wind field distribution with high-temporal and high-spatial resolution in real time under clear sky, which has been an important means to study atmospheric wind field. Firstly, the significance of atmospheric wind field measurement is briefly described, and the technology of laser coherent wind measurement is introduced. Then combined with the development of coherent Doppler wind lidar, the application of coherent laser wind detection technology in different fields has been analyzed and summarized. Finally, the application prospect of coherent detection technology is further analyzed by comparing the application defects of current coherent detection technology.
