借助一套全新的地面高精度光电探测器强光感生噪声检测平台，建立了强光感生噪声精细结构扣除模型，同多通道信号接收技术相结合，改进了一台用于中高层大气温度探测的子午工程双波长三通道瑞利散射激光雷达数据的处理方法。处理后数据反演的大气温度廓线与TIMED卫星结果相比较，得到了很好的吻合。在35～85 km高度范围内二者反映了较一致的温度分布特征，30~55 km温度误差小于±5 K,55~75km温度误差小于±10 K。

A new grounded precious experimental method is proposed for identifying signal-induced noise (SIN) originated in the photoelectric detector, as well as establishing a fine structure SIN model for its deduction from raw Lidar signals. The method of data process of a dual-wavelength Rayleigh scattering lidar with multi-channels enrolled in the meridian project is improved. Temperature profiles obtained by calibrated data show the coincident distribution with the TIMED satellite over the altitudes of 35 km to 85 km, temperature bias between them is less than 5 K from 30 km to 55 km, less than 10 K from 55km to 75 km.
