Abstract
In an example method, a vehicle configured to operate in an autonomous mode could have a radar system used to aid in vehicle guidance. The method could include a plurality of antennas configured to transmit and receive electromagnetic signals. The method may also include a one or more sensors configured to measure a movement of the vehicle. A portion of the method may be performed by a processor configured to: i) determine adjustments based on the movement of the vehicle; ii) calculate distance and direction information for received electromagnetic signals; and iii) recover distance and direction information for received electromagnetic signals with the adjustments applied. The processor may be further configured to adjust the movement of the autonomous vehicle based on the distance and direction information with adjustments applied.
