The process of feature extraction is to transform the eradiate noise signal to different feature space and extract the feature vectors that reflect the category of the input sample. The extracted features are the input modes to the classifier. Through the inspecting, the author selected three methods of eradiate noise's feature extraction.

本文作者经过考察，采用了三种前期研究中较为有效的水下目标特征提取方法——基于功率谱估计的线谱特征提取方法、基于小波分析的不同频段内能量特征提取方法和基于水声信号分维特性的特征提取方法。

Increasing the input noise may increase the signal-to-noise ratio of the output response V(t within the element's parameter region indicating that the periodic components of V increase as the input noise increases. The relationsip between the variation of the SNR of the V curve and the noise is similar to the that of the resonance.

结果表明：在一定的条件下，增大输入噪声的值不仅不降低输出响应信噪比；反而迅速增加输出响应的信噪比，使输出响应中周期信号的分量反而加强，而且输出响应的信噪比对于输入噪声的变化具有&共振&形状的曲线。
