Abstract:
Methods and apparatus utilizing time division access of multiple radar transceivers in living object detection for wireless power transfer applications are provided. In one aspect, an apparatus for detecting an object in a detection area of a wireless power transfer system is provided. The apparatus comprises a plurality of radar transceivers. The apparatus comprises a processor configured to group the plurality of radar transceivers into pairs of radar transceivers. The processor is configured to instruct each of the pairs of radar transceivers to transmit radar signals during a corresponding time slot of a plurality of time slots. The processor is configured to instruct each of the pairs of radar transceivers to receive the radar signals during the corresponding time slot of the plurality of time slots. The processor is configured to detect the object in the detection area based on at least some of the radar signals received by each of the pairs of radar transceivers.
