It is usual to employ a Green's function technique to develop the mathematical framework to describe scattering from two or more objects or objects near a reflecting interface. The method is perforce rather specific and tedious to develop and leads to a form not very susceptible to physical interpretation. In this work a method is demonstrated that enables one to describe scattering from multiple targets or targets near an interface that is (1) independent of the target boundary conditions, (2) independent of the scattering theory for the single scatterer, and (3) that enables one to gain insight in the scattering process that is not manifest in the usual formulations. Then the method is applied to several classes of targets and raise some issues of how the usual theories are implemented that is apparent from this formulation but not apparent in the usual integral equation--Green's function approach.
