用子波变换提取目标回波波形特征

Feature Extraction of Radar Target Return by Wavelet Transform

本文分析了子波变换及其在特征提取中的应用，具体讨论了在Ｈａｒｒ子波基底下，用Ｍａｌｌａｔ算法提取雷达目标回波波形特征的实例，从中可以看到子波变换用于特征提取的很有潜力的发展前景。

In this paper, wavelet transform and its application to feature extraction are analyzed. In particular, feature extraction of radar target return by Mallat algorithm under Harr waveletbase is discussed. The preliminary results are presented. It follows that feature extraction by wavelettransform is regarded as a promising research project.
