Abstract :
In this paper power cepstra measured in shallow waters are derived theoretically to show how a sound source propagating via different paths interferes. From the derivation several useful properties of the power ceptra are revealed, which could be used to classify rahmonic tracks generated by different paths and mechanisms. Sea trial data measured in a shallow water bay are analyzed to verify the properties of the power cepstra.
