A mathematical framework for analysing the spatial resolving capability of a general three-dimensional bistatic synthetic aperture radar imaging system, in which the transmitter, receiver and imaged object (or region of interest) may be non-coplanar and in which the transmitter and/or receiver may be moving, is presented. With Earth observation applications in mind, this framework is used to characterise quantitatively the two-dimensional ground-plane resolving capability of the three-dimensional imaging system. The theoretical results are confirmed via simulations.
