The expressions allowing one to calculate the resulting
field of an opaque source, and also the field of scattering of a heterogeneity
for located in the Fraunhofer zone for plane-layered waveguides are given.
In both cases the amplitude of scattering of the heterogeneity is needed
to be known. The restriction on uniformity of a water layer is removed
except for the layer containing a heterogeneity.
