Abstract

Abstract:

Aiming at improving the EMD denoising performanc for the Mie scattering radar signals,a multiple clear iterative interval-thresholding(EMD-MCIIT)is used in EMD denoising. The multiple IMFs is firstly employed and the alter function is used to change the noise signals,and then the signal is denoised by the iterative interval-thresholding. Through simulation and the experiment of real radar returning signals,it turns out that compared with the traditional EMD threshoding methods the proposed approach can denoise effectively and the SNR is improved. Therefore,the demonstrated technique has a promising future.

Key words: experience mode deposition (EMD), multiple clear iterative interval, threshoding (EMD-MCIIT), Mie scattering lidar, denoising
