  • In order to improve the efficiency of atmospheric signal processing of lidar,the theory of empirical mode decomposition was analyzed and the application of empirical mode decomposition in real-time processing of atmospheric echo signal was studied.The reconstruction signal after empirical mode decomposition processing is close to the signal after 100 singnals average and their correlation coefficient is 0.99 and the processing time can be decreased to 1%,which may meet the requisition of real-time processing and can restrain the interference of some thin cloud.This result will give help to real-time processing of lidar echo.
