Ray stability in weakly range-dependent sound channels
Ray stability in weakly range-dependent sound channels
Ray stability is investigated in environments consisting of a range-independent background sound-speed profile on which a range-dependent perturbation is superimposed. Theoretical arguments suggest and numerical results confirm that ray stability is strongly influenced by the background sound speed profile. Ray instability is shown to increase with increasing magnitude of α(I)=(I/ω)dω/dI, …
