Automotive synthetic aperture radar with radon transform

A system for applying Synthetic Aperture Radar (SAR) in a land vehicle to perform a maneuver, the system comprising a controller configured to:

• receive digitized radar return data from a pulsed radar transmission from a Synthetic Aperture Radar (SAR) onboard a land vehicle;
• accumulate a plurality of frames of the digitized radar return data;
• apply 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;
• generate 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
• perform an autonomous or semiautonomous maneuver with the land vehicle by applying the generated two-dimensional X-Y map.

A non-transitory computer readable medium encoded with programming instructions causing a processor in a land vehicle to perform a method for using Synthetic Aperture Radar (SAR) to perform a maneuver with the land vehicle, the method comprising:

• accumulating a plurality of frames of 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.
