测风激光雷达鉴频器的性能研究
|
摘要
F-P标准具作为测风激光雷达Rayleigh通道的鉴频器,其性能决定了测风精度和测风激光雷达的性能,F-P标准具通过将频率变化转化为能量变化来进行鉴频,不同频率的回波信号具有不同的透过率,但标准具的透过率受到诸多因素的影响,文章从Airy曲线出发,研究了不同因素对标准具透过率的影响,峰值透过率随不同因素的变化规律和变化速率,为测风激光雷达的仿真、设计和研究仪器测量误差提供参数依据。
As an optical frequency discriminator for the Rayleigh channel of the Doppler wind lidar,the performance of F-P etalon determines the accuracy of the wind measurement and the performance of the Doppler wind lidar. The F-P etalon converts the frequency change into energy change for frequency discrimination,echo signals with different frequencies have different transmittances,and the transmittance of the etalon is affected by many factors. From the Airy curve,the influence of different factors on the transmittance of the etalon is studied,and the change rule of peak transmittance with different factors is obtained. It provides the parameter basis for the simulation,design and the measuring error of Doppler wind lidar.
