基于提升小波改进阈值的雷达信号去噪方法
Method of radar signal de-noising based on lifting wavelet improved threshold
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.关键词
