Electronic Device with Co-Located Independent Radar Transceivers

Abstract:

An electronic device that performs radar measurements is described. This electronic device includes independent, co-located radar transceivers, and the independent radar transceivers are not synchronized with each other. Moreover, the radar transceivers may have different fields of view that partially overlap. During operation, the radar transceivers transmit radar signals and perform the radar measurements. Then, based at least in part on the radar measurements, the electronic device determines a location of an object in an environment around the electronic device. For example, the location may include an angular position that is determined from the amplitudes of the radar measurements performed using at least a subset of the radar transceivers. Furthermore, the object may be an individual, and the electronic device may identify the individual based at least in part on the radar measurements. Note that the radar measurements performed by a given radar transceiver do not provide angular information.
