| 摘 要： | Incoherent Doppler lidar for measuring wind field has been developed for a decade. Two kinds of incoherent Doppler lidar have been used to measure Mie and Rayleigh backscattering to retrieve atmosphere wind field: one is the fringe imaging technique and the other is the edge tech-nique. Chanin et al. demonstrated the technique of measuring stratospheric wind profile from 25—60 km altitudes using 532 nm laser and double Fabry-Perot interferometer[1], with backscattering signal discriminated …

| Abstract: | A mobile incoherent Doppler lidar system has been experimentally demonstrated to be able to transmit reliable single frequency operation laser pulse, even after truck transit and in very high vibration environments. The linewidth of the injection-seeded pulse Nd:YAG laser can be measured by means of an I2 molecular filter. And, lidar validation experiments demonstrated the feasibility and capability of measuring wind field by the Mie-Rayleigh Doppler wind lidar. The un-certainty of measured wind speed is 0.985m/s in the altitude range from 2 to 4 km. |
