Mathematical models and time-frequency heat maps for surface gravity waves generated by thin ships
Nicholas R. Buttle, Ravindra Pethiyagoda, Timothy J. Moroney +4
Recent research suggests that studying the time-frequency response of ship wave signals has potential to shed light on a range of applications, such as inferring the dynamical and…
Spectrogram analysis of surface elevation signals due to accelerating ships
Ravindra Pethiyagoda, Timothy J Moroney, Gregor J Macfarlane +1
Spectrograms provide an efficient way to analyse surface elevation signals of ship waves taken from a sensor fixed at a single point in space. Recent work based on a simplified mod…
Time-frequency analysis of ship wave patterns in shallow water: modelling and experiments
Ravindra Pethiyagoda, Timothy J. Moroney, Gregor J. MacFarlane +2
A spectrogram of a ship wake is a heat map that visualises the time-dependent frequency spectrum of surface height measurements taken at a single point as the ship travels by. Spec…
