首先将变换后的时频矩阵分割为子领域，从子领域中检测频时频支撑领域，然后

First, when the frequency transformation matrix is ​​divided into sub-domains, the support from the sub-field frequency is detected in the frequency field, and uses a single source detection algorithm based on the feature value decomposition of the art, factor detector configured single-source, single-source field detection completion.

First of all, the transformed time-frequency matrix is divided into sub-domains, the frequency-time support area is detected from sub-domain, and then a single-source field detection algorithm based on characteristic value decomposition is used to construct a single-source detection factor and complete single-source field detection.

Firstly, the transformed time-frequency matrix is divided into sub domains to detect the frequency time-frequency support domain from sub domains. Then, the single source domain detection algorithm based on eigenvalue decomposition is used to construct the single source detection factor to complete the single source domain detection.<br>
