Abstract
A vehicle, driving system and method for driving a vehicle is disclosed. The driving system includes a radar system, a processor and an autonomous driving system. The radar system obtains an SAR measurement of a static object in an environment of the vehicle. The processor obtains a first estimate of a location of the vehicle in the environment, obtains from a database a representation of a static object in the environment associated with the first estimate of the location, and compares the SAR measurement of the static object to the representation of the static object from the database to obtain a second estimate of the location of the vehicle. The autonomous driving system drives the vehicle through the environment based on the second estimate of the location of the vehicle.
