1. A method for authenticating a user of a car, the method comprising:
transmitting a plurality of radar signals through a predetermined portion of a surface of the car towards a portion of a hand of the user using a millimeter-wave radar;
receiving reflected radar signals from the portion of the hand using the millimeter-wave radar;
generating a fingerprint signature based on the reflected radar signals;
comparing the fingerprint signature to a database of authorized fingerprint signatures; and
authorizing the user based on whether the fingerprint signature matches an authorized fingerprint signature of the database.
