The object of this thesis is to recover the missing elements of the spectral matrix in the case that the acoustical field is highly coherent so as to ... L Yu,Jerome Antoni,Q. Leclère 被引量: 3发表: 2015年 加载更多来源期刊 Inter Noise & Noise Con Congress & Conference Proceedings ...
The least‐squares expansion of a rank‐N cross‐spectral matrix obtained from a vertical array of Nhydrophones in terms of M (M≤N) dyads of eigenvectors of its larger eigenvalues plus a diagonal uncorrelated noise matrix was investigated. For M propagating modes the expansion allows the stripp...
Cross spectral matrixDaniell's methodFrequency domainRotating beamformingIn microphone array techniques the cross spectral matrix is used to localize acoustic sources. In this paper Daniell's method is revisited to average the cross spectral matrix of the sensor signals in the frequency domain. It is...

After the multi-dimensional cross spectrum matrix introducing on the basis of classical time series cross spectrum, we analyzed the eigenvalue and characteristic vectors of cross spectrum matrix on a interested frequency range. 在经典时间序列的交叉谱分析基础上 ,建立多维交叉谱矩阵 ,对某一感兴趣的频...
6) cross-spectral density matrix 互谱密度矩阵补充资料:功率谱密度估计 随机信号的功率谱密度用来描述信号的能量特征随频率的变化关系。功率谱密度简称为功率谱,是自相关函数的傅里叶变换。对功率谱密度的估计又称功率谱估计。平稳随机信号x(t)的(自)功率谱Sxx(ω)定义为 (1) 式中rxx(τ)为平稳随机信号的...

Small karst aquifers have a negligible ability to retain water, and are much more susceptible to change of the input signal, as opposed to large karst aquifers (such as the aquifer of the Kupa spring) which, even in the case of extremely large karstification, due to the matrix and ...
