Abstract: This paper proposes an original method for improving the time-frequency representation for signals dedicated to structural diagnostics. The proposed method smooths the time-frequency representation by decreasing the false amplitudes indicated by lateral lobes. It also permits withdrawing information in the time-frequency representation that occurs if bilinear distribution functions are involved in the analysis. Along with the description of the method, we present examples for a complex signal, composed of two sinusoids. This method allows observing the evolution of the frequencies in time, which proves its efficiency in the theory of analysis and diagnosis of signals. [ABSTRACT FROM AUTHOR]
