基于MATLAB和小波变换的主动声纳回波数据消噪处理

Denoising Processing of Active Sonar Echo Data Based on MATLAB and Wavelet Transform

应用Matlab实现了主动声纳回波信号原始实验数据的读取及分析处理,并给出了利用Matlab进行主动声纳回波数据小波变换消噪处理的实例。应用小波变换对主动声纳回波数据进行消噪处理不仅改善了信噪比,而且保持了很好的时间分辨率。

This paper has implemented the reading, writing and analysis of the raw experimental data of the active sonar echo signal by utilizing the Matlab language and has given some real exarnples for the denoising processing of the corresponding data based on the Matlab and the wavelet transform. The examples have shown that the denoising processing of the active sonar echo data based on the wavelet transform can not only raises the signalto-noise ratio but also keep high time resolution.
