In this paper, we analyze the resolution of bistatic synthetic aperture radar (BISAR) imaging for stationary objects. In particular, we analyze the resolution of images reconstructed by the method of a filtered backprojection inversion, an inversion method which is derived from a scalar wave equation model.
