中文摘要：

通过分析CCD成像特点,设计了侧向散射激光雷达几何标定实验,得到CCD各像元的角宽度,并确定了CCD像元与散射光位置之间的对应关系.对两次实验中采集的回波信号进行标定,并分别与POM02进行相函数比对、与后向散射激光雷达进行探测信号比对,结果表明：相函数廓线和POM02测量结果相吻合;侧向散射激光雷达信号与后向散射雷达的距离修正信号在650m以上的变化趋势一致.侧向散射激光雷达弥补了后向散射激光雷达在近地面段不能探测气溶胶的不足,该标定方法可靠,为进一步利用侧向散射激光雷达研究近地面气溶胶的时空分布奠定了坚实的基础.

英文摘要：

The imaging characteristics of CCD were analyzed,ageometric calibration experiment on sidescatter lidar was designed,the each CCD pixel angle was achieved,and the relation between CCD pixels and the position of scattered light was established.Two experimental signals were calibrated using this method.The calibrated results are compared with POM02 in aerosol phase function,and with the backscattering lidar in signal,respectively.The comparison results indicate that the profiles of aerosol phase function from this method and from POM02 are same,and the signal from side-scatter lidar has the same tendency with the range-corrected signal from backscatter lidar above 650 m.Moreover,side-scatter lidar overcomes the shortcoming that the backscatter lidar can not detect the full signals in near range.This calibration method is reliable and useful for further studying the spatial-temporal aerosol profile in near surface by side-scatter lidar.
