| Abstract: | When the f reguencies of two noise Sourcies are the same or approximately the same, it is difficult to distinguish one noise from another by spectrum analysis. In the present paper, based on coherence analysis , this problem is solved by calculating the proportion of the noise energy emitted from each of the noise sources , taking the noise energy as a whole. |
