Abstract
By using a variational principle for scattering by rough interfaces, the functional derivative of the scattered part of an acoustic field originating from a point source is derived directly in the time domain. This general result is specialized to the case of scattering by surfaces on which fields satisfy Dirichlet boundary conditions. It is shown that when the small-slope approximation is used for surface fields, a simple result can be obtained for monostatic scattering.
