The method of two-scale expansions for weakly irregular oceanic wave- guides perturbed by a current. (Russian. English summary) Zbl 0588.76146
The two-scales expansions method is generalized in the cases of weak irregular surface and of depth waveguides, perturbed by a current. This generalization gives possibility to estimate the influence of the current on the sound transmission in these two cases.
