摘要：

Time-frequency distributions (TFD) describe a signal in terms of its joint time and frequency content. In this paper, the TFD analysis of the electromagnetic scattering from a circular waveguide cavity is investigated. Two time-frequency representations, the Wigner distribution and the running-window Fourier transform, are applied to the frequency-domain scattering data and the results are compared. For the cavity, propagating modes and cutoff frequencies can be determined from the TFD, whereas neither time nor frequency representations will directly provide such information.
