Samsung patents radar method to distinguish object motion types
Samsung describes an electronic device that uses a radar antenna to detect moving objects. It analyzes the signal's speed and power to match the movement against known patterns, allowing the device to identify specific types of motion.
In the filing’s own words
An electronic device includes a radar antenna configured to transmit and receive an RF signal, and a processor configured to identify motion of a target object based on a signal received through the radar antenna. The processor configured to obtain a Doppler velocity of the target object, and power of a tone signal obtained in an operation of detecting the target object during a measurement time, obtain a power distribution of the tone signal according to the Doppler velocity, calculate a first correlation value between the power distribution and a first reference distribution corresponding to first motion of the target object, and a second correlation value between the power distribution and a second reference distribution corresponding to second motion of the target object, and determine the motion of the target object as the first motion in response to the first correlation value being greater than the second correlation value.
What exactly they claim (claim 1)
1. An electronic device, comprising: a radar antenna configured to send and receive a radio frequency (RF) signal; and a processor configured to identify a motion of a target object based on a signal received through the radar antenna, the processor further configured to, obtain a Doppler velocity of the target object and power of a tone signal obtained in an operation of detecting the target object during a measurement time; obtain a power distribution of the tone signal according to the Doppler velocity; calculate a first correlation value between the power distribution and a first reference distribution corresponding to a first motion of the target object, and a second correlation value between the power distribution and a second reference distribution corresponding to a second motion of the target object; and determine the motion of the target object as the first motion in response to the first correlation value being greater than the second correlation value.
