Doppler wind lidar data acquisition system and data analysis by empirical mode decomposition method

Abstract

This paper describes the realization of the wind lidar data acquisition system, and a method of denoising signal based on empirical mode decomposition (EMD). The paper proposes a method for raveling out the edge problem that comes with EMD. It has been proved to be a good method for solving the edge problem in analyzing lidar data. We can improve the ratio of signal to noise by using the EMD method three times more than the original's. It has been proved to be better than adjacent averaging in data processing.
