In regular airborne Synthetic Aperture Radar applications the quality of the processed image depends on the accuracy of the flight path measured by an inertial navigation system. Usually, only approximated flight paths are available. Autofocus techniques sharpen the resulting images, but do not correct the flight path. In this paper we present a method to reconstruct the exact flight path from the focused image and the range compressed data. We show that the flight path can be reconstructed precisely for a wide antenna beam of more than 20deg.
