Abstract: An electronic device may include sensing circuitry that transmits a radar signal over one or more antennas. The sensing circuitry may receive a reflected radar signal over the antenna(s). Transmission of the radar signal may produce a leakage signal that is combined with the reflected radar signal. A mixer may generate a beat signal based on the radar signal, the reflected radar signal, and the leakage signal. A sensing receiver may perform motion-based external object detection to detect the presence of an animate external object that is very close to the device. The sensing receiver may perform the motion-based detection based on time fluctuations in the power and/or phase of the signal without removing or cancelling the leakage signal.

Abstract: Systems and methods for determining fine grain motions and vibrations of live and/or inanimate objects are described based on using a radar system. For example, biometric information may be extracted from such vibrations associated with a live object. In different embodiments, processing circuitry may perform different statistical analysis on reflections from the objects. Moreover, the processing circuitry may perform different processing functions based on the statistical analysis to determine the vibrations with high accuracy. Furthermore, the processing circuitry may also select one or multiple target maps based on a field of view of the radar system for a more robust measurement of the vibrations associated with one or multiple objects.
