摘要

Abstract

Aimed at the shortcomings and limitation of threshold de-noising in wavelet, a new threshold function is introduced based on lifting wavelet. It gains the wavelet coefficient in noising signal through lifting wavelet, and makes use of the new threshold function to process signal de-noising. The simulation results manifest that the new threshold function can suppress the noise effectively and gain a faster processing. It is better than classical threshold function and the existing improved threshold functions in SNR and MSE and it has high practical value in the radar dim target detection.
