Abstract :
We propose a geometry and inversion methods for a multistatic, downlooking SAR mode using simple antennas. The resulting generalized Radon transform takes line integrals over ellipses of changing aspect ratio. We apply the method of approximate inverse to the inversion of this transform and show the results of the numerical inversion.
