摘要
Mode tracking plays an important role in characteristic modes analysis. However, mode tracking in a proper and efficient way is still a challenging work. Based on modal linear correlation and modal stability, a double modal parameter tracking method is proposed in this paper, which is to track modes by correlating eigenvector and calculating the stability of characteristic angle simultaneously. To eliminate ambiguity case of multi-mode mapping one mode, two sorted mode with max Pearson correlation coefficient are identified same mode by utilizing saving best function. In order to verify accuracy and efficiency of the proposed method, four representative structures are analyzed. It can be observed that the proposed tracking method works better than the traditional methods.
