1. An electronic device to measure vital signs, the electronic device comprising:
a camera to capture an image;
a radar antenna including an array of antennas; and
at least one processor circuitry to:
identify a subject in the image;
identify a location of the subject in an environment;
energize a first subset of the antennas when the subject is in a first location in the environment to steer radar signals toward the first location; and
energize a second subset of the antennas when the subject is in a second location in the environment to steer radar signals toward the second location; and
determine a vital sign of the subject based on a reflected radar signal.
