The imaging characteristics of CCD were analyzed,a geometric calibration experiment on side-scatter 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.
