Abstract

Abstract: Because of its high detection accuracy, fast response time and compact system structure, coherent lidar has made great progress in the field of wind measurement and has become one of the most advanced wind measurement tools in recent years. It shows that coherent lidar has good research significance and application prospects. The technical advantages of coherent laser wind measuring radar are briefly introduced, and two kinds of coherent wind radars using continuous laser and pulsed laser as light source are described in detail. The development history and the latest progress of these two technologies at home and abroad are mainly focused, and at last the development trend of coherent laser wind measuring radar is summarized from the choice of light source wavelength, the way of laser working and the diversity of application platform.

Key words: atmospheric optics, coherent detection, wind measurement, pulsed laser, continuous laser
