Abstract：We show that Spotlight-mode synthetic aperture radar imaging can be interpreted as a tomographic reconstructing problem along the upper-half circular curves. Using the extrapolation of an analytic function and inversion of Radon transform along the upper-half circular curves, we obtain the uniqueness theorems of imaging and partial explicit reconstructive formula.
