为验证此方案，在半消声室进行了非典型声强向量阵的定向实验，用3个扬声器模拟体积目标3个不同部位的声源。

To test this scheme, experiment was conducted in a semi-anechoic chamber, with 3 loudspeakers simulating the sound sources of the 3 separate sections of the volume target.

其中，对于观测向量协方差阵的谱分解估计，我们很容易得到它在一些损失下的风险函数。

Thereinto, for the spectral decomposition estimate of the covariance matrix , we can gain the risk functions under some losses.

对于算法中涉及的求高阶实对称阵的最大特征值及其特征向量，采用幂法加以实现。

As for computing the largest eigenvalue and its eigenvector of a higher-order real symmetric matrix in the algorithm, the power method is used.
