1. A method for determining a location of a vehicle, comprising:
- acquiring a plurality of sensor data traces from a radar sensor associated with the vehicle;
obtaining velocity information from the plurality of sensor data traces;
using the velocity information, identifying a portion of the plurality of sensor data traces corresponding to a moving object;
removing the portion of the plurality of sensor data traces corresponding to the moving object from the plurality of sensor data traces;
obtaining an approximate location of the vehicle using a GPS unit;
comparing the sensor data traces to a database of geo-referenced sensor data traces; and
based on the comparison, determining the location of the vehicle.
