介绍了气动板形检测辊的板形信号检测原理，详细阐述了普通多项式最小二乘法、正交多项式最小二乘法和基于欧氏距离的模糊模式识别法，利用虚拟仪器LabVIEW软件开发了基于上述三种方法的板形模式识别系统。

The detailed coefficients of DWT contain signal and noise. Instead of the soft-thresholding method, SVD is applied to decompose the signal features and noise into different orthogonal subspaces. With the reconstruction of the singular vectors in subspace, the signal features are extracted effectively.

该方法通过对每层小波分解细节系数进行奇异值分解，将其中的信号特征成分和噪声分解到不同的正交子空间中，在子空间中选取集成信号特征成分的奇异值矢量进行重构，从而提取出淹没在细节系数中的有用信号成分，最后进行小波重建，得到降噪信号。

Based on the array signal processing and the eigenstructure decomposition method, the signal subspace and the noise subspace are achieved by reconstructing and decomposing the data matrix collected by the array sensors. By using the orthogonal properties of the two subspaces, the information about the velocities and bearings of spatial moving targets can be exactly obtained.

本文提出一种超分辨的二维谱估计方法，它利用的是阵列处理技术，对天线接收数据进行本征分析，将信号数据张成一个空间并对其进行分解，根据正交原理分割成信号子空间和噪声子空间，构造出噪声本征矢量，利用信号子空间与噪声子空间的正交性，在空间谱上形成极值点，从而达到对方向和速度的二维高分辨率估计。
