The far-field asymptotics of the linear waves excited by a moving object ar
e obtained for a fluid consisting of n density layers (n is arbitrary). The
structure of the perturbations of free surface and density interfaces is a
nalyzed as a function of the depth of the object and its velocity. The ampl
itudes of different types of waves are compared. The present model also con
firms and generalizes the features of the ship waves that were known previo
usly only for the cases of one-layer and two-layer fluids.
