摘要
简要介绍了小波去噪的主要作用、特点和发展现状,分析了小波对普通信号的去噪效果。结合小波去噪的具体应用实例,通过使用两种不同的小波去噪方法,分析比较其对侵彻弹体加速度信号的去噪效果,讨论使用不同小波去噪方法的特点,并分析不同背景下小波去噪方法的选择。
The wavelet denoising＇s main function,characteristics and development situation is briefly introduced,and the effect of wavelet denoising to ordinary signal is analyzed.Combined with the concrete application of the wavelet denoising,the denoising effects of acceleration signal of penetrating missile body by two denoising methods are compared.The different characteristics of wavelet denoising methods are discussed,the selection of wavelet denoising methods is analyzed.
