1. A method for using Synthetic Aperture Radar (SAR) to perform a maneuver in a land vehicle, the method comprising:
receiving digitized radar return data from a pulsed radar transmission from a Synthetic Aperture Radar (SAR) onboard a land vehicle;
accumulating a plurality of frames of the digitized radar return data;
applying a RADON transform to the accumulated plurality of frames of the digitized radar return data and odometry data from the land vehicle to generate transformed frames of data for each three-dimensional point, wherein the RADON transform is configured to perform coherent integration for each three-dimensional point for which a radar return exists from the pulsed radar transmission, project a radar trajectory onto each three-dimensional point, and project Doppler information onto each three-dimensional point;
generating a two-dimensional X-Y map of an area covered by the pulsed radar transmission from the SAR based on the transformed frames of data for each three-dimensional point; and
performing an autonomous or semiautonomous maneuver with the land vehicle by applying the generated two-dimensional X-Y map.
