Research output: Contribution to conferencePaperpeer-review


In this paper we investigate the feasibility of using time-frequency distributions to measure time-localized phase and group velocities given wave elevation time series measured at two points spatially separated in the direction of wave propagation. The results are compared to those obtained experimentally from classical Fourier-based cross-power spectra, which of course provide no time localization, and to theoretical estimates of phase and group velocity.
