摘　　要：介绍了双光栅转动拉曼激光雷达的双光栅单色仪结构,并推导了相应的雷达公式。利用该公式把双光栅单色仪带宽对雷达反演温度带来的影响,简单地转化成双光栅单色仪带宽内包含的转动拉曼谱线对雷达反演温度带来的影响,结果表明多谱线比值反演的温度小于单谱线反演的温度,最大误差达13K。The double grating monochromator structure of pure rotational Raman lidar is introduced and the corresponding lidar equation is deduced. To a pure rotational Raman-lidar of double grating monochromator, influences of bandwidth on temperature＇s reversion can be changed into influences of Raman lines contained in the bandwidth on temperature by the lidar equation. Results show that temperature from multiple Raman lines＇ ratio method is lower than that from single Raman line, and the maximum error is 13 K.
