We theoretically show the possibility of reducing the scattering and intrinsic radiation fields of a body when using an active suppression system that includes a layer of monopole radiators that cover its surface and to which a local negative velocity (acceleration) or pressure feedback on the outer surface is applied. The radiators are controlled by signals from the receivers located on an additional outer surface. We have carried out an experiment that confirms the derived relations for the one-dimensional case of intrinsic radiation field suppression.
