This paper addresses the problem of imaging from (inverting) the data collected by a physical or synthesized array. A scattering model describing the source/object interaction is presented. The inversion based on this model is a computationally manageable method that incorporates the radiation pattern of each element on the array at the transmit and receive modes. This study indicates that a physical array and its synthesized counterpart possess the same resolution despite the fact that the synthesized array's signal subspace is a subset of the much larger signal subspace for the physical array.
