Microlocal aspects of common offset synthetic aperture radar imaging

In this article, we analyze the microlocal properties of the lin- earized forward scattering operator F and the reconstruction operator F F appearing in bistatic synthetic aperture radar imaging. In our model, the radar source and detector travel along a line a xed distance apart. We show that F is a Fourier integral operator, and we give the mapping properties of the projections from the canonical relation of F , showing that the right projection is a blow-down and the left projection is a fold. We then show that F F is a singular FIO belonging to the class I 3;0 .
