Abstract
The convolution effect in CO2 lidar return signals caused by the long laser pulse is analyzed by modifying the original lidar equation and introducing a correction function Cr(R). The characteristics of Cr(R) are discussed in detail, leading to a deconvolution technique consisting of a two-step iteration procedure for the extraction of both the backscattering coefficient and the gas species content in differential absorption lidar measurement.Keywords
