The localization of interference associated with crossing modes in the time-frequency (TF) plane is of significant interest when the objective is to separate these modes. Prior to localizing mode crossings, it is essential to determine whether the observed interference arises from closely spaced modes or from actual mode crossings. In this paper, we propose a novel technique to discriminate between these different types of interference in the TF plane and to subsequently localize mode crossings. The proposed approach exhibits strong adaptability across a wide range of scenarios and demonstrates robustness to noise, as confirmed by simulation results.

Abstract
The localization of interference associated with crossing modes in the time-frequency (TF) plane is of significant interest when the objective is to separate these modes. Prior to localizing mode crossings, it is essential to determine whether the observed interference arises from closely spaced modes or from actual mode crossings. In this paper, we propose a novel technique to discriminate between these different types of interference in the TF plane and to subsequently localize mode crossings. The proposed approach exhibits strong adaptability across a wide range of scenarios and demonstrates robustness to noise, as confirmed by simulation results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
