Abstract: In an embodiment, a method for authenticating a user of a car includes: transmitting a plurality of radiation pulses 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 a reflected signal from the portion of the hand using the millimeter-wave radar; generating a fingerprint signature based on the reflected signal; 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 of authorized fingerprint signatures.

Abstract: An embodiment method includes: receiving radar data at a millimeter-wave radar sensor, the radar data being generated in response to an incident radio-frequency signal reflecting off an object located in a field of view of the millimeter-wave radar sensor; filtering the radar data to generate a first-filtered signal; determining a trajectory of motion corresponding to the first-filtered signal; and determining whether the trajectory of motion corresponds to a human signature, the human signature being associated with a respective operation of a vehicle.
